Explanation: There are three basic types of traffic sign: those that warn, those that inform and those that give orders. Generally, triangular signs warn, rectangular signs give information or directions, and circular signs give orders. An exception is the eight-sided ‘stop’ sign.

How can you identify a sign that gives orders?
Different shapes have different meanings – There are hundreds of different road signs, each with their own meaning. However, most fall into one of three categories based on their shape. The general rule is:
Circular road signs: Circular signs give orders – they must be followed to stay within the law. Circles with a red border tell you what you must not do (e.g. take a U-turn). Blue circles usually give a positive instruction, such as ‘turn left ahead’. Triangular road signs: Triangular signs warn. Road signs in the shape of an equilateral triangle are designed to warn you about the road layout or any hazards that lie ahead, such as sharp bends. They almost always have a red border. Rectangular road signs: Rectangular signs inform. Blue rectangular signs give information on motorways, green signs direct you on primary roads, while white signs give directions on minor roads. Rectangular signs can also indicate bus lanes and congestion charge zones.
Many road signs, such as speed limits, should be self-explanatory; but some aren’t quite so straightforward. Here, we look at a few of the most common traffic signs in more detail – and some that are commonly misunderstood.
What shape is the standard sign giving the order to stop?
History – Yellow U.S.1924–1954 stop sign The first ever stop sign was created by Detroit police sergeant Harold “Harry” Jackson, who was working as a traffic guard at a busy city intersection. One of the cross streets had a particularly low-visibility turn entering the intersection, almost always forcing Sgt.
- Jackson to slow down and hold back the traffic entering from that street.
- Looking for ways to make his job easier, he took a rectangular piece of plywood, cut off the corners to give it a distinct shape, wrote “STOP” over the center and placed facing the street.
- He noticed that his innovation improved the overall traffic flow through the intersection.
After he shared his experience with fellow officers at a meeting, the practice started to spread across the city intersections. Next year, stop signs were adopted across Michigan, The first ones had black lettering on a white background and were 24 by 24 inches (61 cm × 61 cm), somewhat smaller than the current sign.
As stop signs became more widespread, a rural-dominated committee supported by the American Association of State Highway Officials (AASHO) met in 1922 to standardize them and selected the octagonal shape that has been used in the United States ever since. The unique eight-sided shape of the sign allows drivers facing the back of the sign to identify that oncoming drivers have a stop sign and prevent confusion with other traffic signs.
Another consideration of the AASHO was visibility and driver literacy, as summarized in subsequent State Highway Commission reports in the states of the U.S., was that the goal for signs “standardized throughout the Union” was that “The shape of the sign will indicate what it will mean.
- This has been worked up very carefully by the best qualified men in the country and men who have made a thorough study of this question.
- It has been found that so many people have trouble in reading the sign that the shape of the sign is very much more important than the reading matter on it.” The octagon was also chosen so that it could be identified easily at night since the original signs were not reflective.
The more urban-oriented National Conference on Street and Highway Safety (NCSHS) advocated a smaller red-on-yellow stop sign. These two organizations eventually merged to form the Joint Committee on Uniform Traffic Control Devices, which in 1935 published the first Manual on Uniform Traffic Control Devices for Streets and Highways (MUTCD) detailing the stop sign’s specifications.
- The MUTCD’s stop sign specifications were altered eight times between 1935 and 1971.
- From 1924 to 1954, stop signs bore a red or black stop legend on a yellow field.
- Yellow was chosen because fade-resistant red materials were not available.
- Retro-reflective or self-lit signs were permitted in the 1935 MUTCD; retro-reflective ones were first required by the 1948 edition of the MUTCD, which also called for a 2 + 1 / 2 -foot (0.76-metre) height from the road crown to the bottom of the stop sign.
The 1954 MUTCD newly specified a white stop legend on a red field, and increased the mount height specification to 5 feet in rural areas. Red traffic lights signify stop, so the new specification unified red as a stop signal whether given by a sign or a light.

What are traffic signs and types?
4 Types of Road Signs – There are four different types of road signs: regulatory, warning, guide, and information signs. Some are about prohibitions, while others are about cautions, driving directions, or how to get to specific locations. The shape and color of a traffic sign provide important information about the sign’s message, and in low-visibility road conditions, you may only be able to make out the shape or color of the sign.
- Regulatory signs, which are usually black and white or red and white, indicate or emphasize traffic laws, regulations, or standards.
- They are the laws of the road, and they are intended to convey when a driver can move and at what pace.
- Regulatory signs are color-coded as a way to help drivers understand what is being communicated.
Here’s a guide:
Red: Stopping or danger Black And White: Regulations and laws
What traffic signs are two ways?
Two way traffic signs are posted before or on two-way roadways. These two way traffic signs warn drivers that they’re leaving a one-way roadway and entering a roadway with opposing traffic. This might restrict the driver’s ability to freely pass cars. A diamond shape with two arrow graphics in the center.
How do you identify warning signs?
It seems that everywhere you go on the Ohio State Columbus campus you see and read signs that warn about a variety of hazards. Just as warning signs vary on topics, so do their colors. Students, faculty, and staff may find the color variations of these signs confusing at times.
Red = Danger. OSHA recommends danger signs or tags be red or predominantly red, with lettering or symbols in a contrasting color (usually white against the red background). Red warns of a hazard that could cause serious injury or death. Yellow = Caution. These signs and tags are all yellow or predominantly yellow, with lettering or symbols in a contrasting color (usually black). Yellow often is used for signs that indicate physical dangers that could cause serious injuries, such as slipping, tripping, falling, striking against, and pinch hazards. Orange = Warning. These orange or predominantly orange signs and tags generally have black lettering or symbols. Orange often is used for potentially dangerous parts of machinery or equipment that may cut, crush, shock, or otherwise injure a person. Fluorescent Orange or Orange-Red = Biological Hazard. These signs and tags have lettering or symbols in a contrasting color (usually black). This color designates infectious agents and wastes that pose a risk of death, injury, or illness. Green = Safety Instructions. These signs usually have white lettering against the green background. Some part of the sign also may contain black lettering against a white background. Green is used to designate first aid equipment, emergency eyewash stations, etc. Fluorescent Yellow-Orange = Slow-Moving Vehicles. This color is used, with a dark red reflective border, on slow-moving vehicle triangles.

What are the 3 types of signs?
Signs are divided into three basic categories: Regulatory, Warning, and Guide signs. Most signs within each category have a special shape and color.
What is the purpose of triangular shaped signs?
Triangle signs – usually white with a red border – are here to let you know that you’re approaching a hazard or a place to stop.
What shape are most regulatory signs?
Section 2B.02 Design of Regulatory Signs – Support: Most regulatory signs are rectangular, with the longer dimension vertical. The shapes and colors of regulatory signs are listed in Tables 2A-3 and 2A-4, respectively. Exceptions are specifically noted in the following Sections.
What font do stop signs use?
Standard Alphabets for Traffic Control Devices, more commonly referred to as Highway Gothic, is now the only approved font for the design of traffic signs.
What do the 8 shapes of traffic signs mean?
Preface – Roadway signs in the United States increasingly use symbols rather than words to convey their message. Symbols provide instant communication with roadway users, overcome language barriers, and are becoming standard for traffic control devices throughout the world.
Familiarity with symbols on traffic signs is important for every road user in order to maintain the safety and efficiency of our transportation facilities. The color of roadway signs is an important indicator of the information they contain. The use of red on signs is limited to stop, yield, and prohibition signs.
A white background indicates a regulatory sign; yellow conveys a general warning message; green shows permitted traffic movements or directional guidance; fluorescent yellow/green indicates pedestrian crossings and school zones; orange is used for warning and guidance in roadway work zones; coral is used for incident management signs; ** blue indicates road user services, tourist information, and evacuation routes; and brown is for guidance to sites of public recreation or cultural interest.
- Sign shape can also alert roadway users to the type of information displayed on a sign.
- Traffic regulations are conveyed in signs that are rectangular with the longer direction vertical or square.
- Additional regulatory signs are octagons for stop and inverted triangles for yield.
- Diamond-shaped signs signify warnings.
Rectangular signs with the longer direction horizontal provide guidance information. Pentagons indicate school zones. A circular sign warns of a railroad crossing. The illustration below shows how the shape and color of a sign indicate the nature of the message.

What are the three types of traffic?
You can invest a lot of time and money building something, but if no one ever sees it then what’s the point? – Think about your website. Your social media channels. Your latest offer. Without traffic, it just sits there doing nothing. It’s not like in the movies (and you’re not Kevin Costner).
- Once you’ve built it, you have to bring people to it.
- On the internet, we refer to the people as “traffic.” There are three types of traffic for internet marketing.
- There’s traffic you buy, traffic you control and traffic you own.
- Each type has its advantages and disadvantages.
- As a Marketing Director, you have to start with knowing where to find your ideal customers.
Ask yourself, where on the internet do they hang? Are they on Facebook or Twitter? Pinterest or LinkedIn? What types of searches are they doing? What websites do they frequent? Once you know where to find your potential customers, then you will know where to go to advertise and create content.
What are the three different purposes traffic signs are used for?
Unit: Four Topic: A1 Thru A7 (Please Listen to Narration or read the Paragraphs below )A1. Traffic signs, introduction. Traffic signs are devices placed along, beside, or above a highway, roadway, pathway, or other routes to guide, warn, and regulate the flow of traffic, including motor vehicles, bicycles, pedestrians, equestrians, and other travelers. Traffic signs are used for three different purposes: (a) to regulate traffic, movement, or parking, (b) to warn of potential dangers or changes in road conditions, and (c) to provide information and guidance. A2. Traffic signs, shapes, introduction. Traffic signs have shapes that denote specific meaning. The shape of the traffic sign allows you to quickly determine whether you are being presented with (a) a regulation, (b) a warning, or (c) information or guidance, and sometimes the specific meaning of the sign. A3. Traffic signs, shapes, octagon. This shape is used exclusively for stop signs. A driver should be able to immediately recognize that an octagon-shaped sign means Stop. A4. Traffic signs, shapes, equilateral triangle, point down. This shape is used exclusively for yield signs. A driver should be able to immediately recognize that an equilateral triangle shaped sign pointed down means YIELD to other vehicles and pedestrians. A5. Traffic signs, shapes, circle. This shape is used exclusively for railroad advance warnings and civil defense evacuation route markers. The most common use in California is for railroad advance warning. A driver should be able to immediately recognize that a sign in the shape of a circle is means there is a railroad crossing ahead. A6. Traffic signs, shapes, cross buck. This shape is used exclusively to warn of a railroad crossing. A driver should be able to immediately recognize that a sign in the shape of a cross buck means that there is a railroad crossing ahead.
How many symbols are there in traffic?
2. Cautionary Traffic Signs – Among other traffic signs in India, cautionary signs warn drivers about potential threats or safety hazards ahead on the road. Drivers should take necessary steps or slow down their vehicles according to cautionary signs given on the road.

|Cautions the driver about a right hand curve.
|Left Hand Curve
|Cautions the driver about a left hand curve.
|Right Hair Pin Bend
|Cautions about a sharp right turn.
|Left Hair Pin Bend

|Right Reverse Bend
|Caution the driver that there is a zigzag turn to the right.
|Left Reverse Bend
|Caution the driver that there is a zigzag turn to the left.
|Indicates that there is a steep rising upwards nearby
|Indicates that there is a steep descending downwards nearby
|Narrow Road Ahead

|Cautions the drivers that the road ahead is prone to falling rocks.
|Indicates the presence of ferry service.
What are warning signs and give 3 examples?
Monday May 06, 2019 Traffic signs, also known as roadway signs, are used to denote information or instructions to motorists and pedestrians. They’ve been around for thousands of years, with some of the earliest types consisting of stone milestone markers. #1) Regulatory Constructed with a white background, as per the Manual on Uniform Traffic Control Devices (MUTCD), regulatory signs are used to regulate the flow of traffic in a given area. They provide motorists and pedestrians with instructions on how to move – or not move – through the area.
Examples of regulatory signs include stop, yield, do not enter, no turn on left, no turn on right, no parking, weight limit, speed limit, one way and HOV lane ahead. Because they are used to regulate the flow of traffic, regulatory signs are arguably the most important type of traffic signs. #2) Warning Warning signs differ from regulatory signs in the sense that they inform rather than instruct.
Warning signs are used to warn motorists and pedestrians about a given area. Examples of warning signs include left turn ahead, led reverse turn ahead, right curve ahead, winding road left ahead, hairpin curve ahead, side road at angle, sharp to the right, sharp curve to the left, intersection and hill with grade.
#3) Guide Finally, guide signs live up to their namesake by guiding motorists (not pedestrians) through a given area. They contain essential information about an area, such as location markers. Examples of guide signs include interstate route markers, country route markers, U.S. route markers, state route markers, interchange exit sign, hurricane evacuation route, exit only and roadway junction.
Other Types While regulatory, warning and guide signs are the three primary types of traffic signs used in the United States, there are other types approved by the Federal Highway Administration (FWA). Motorist services and recreation signs, for example, include signs for tent camping, food, lodging, telephone, hospital, emergency services, information, gas, rest area, picnic area, litter barrel, bathrooms and auto mechanic.
- There are also pedestrian and bicycle signs that provide information or instructions to pedestrians and cyclists.
- Commonly used pedestrian and bicycle signs include no pedestrians, bicycle parking, bicycles yield to pedestrians, hill ahead (with bicycle), slippery when wet (with bicycle), pedestrian crossing and bicycle crossing.

What are informative traffic signs?
Informatory Road Signs | Transport Department, Government of Jharkhand These signs are meant to provide information on direction, destination, roadside facilities, etc. to the road user. Following informative road signs helps a driver in saving time, reaching destination without wandering around. These signs are generally facilitators to the driver. These signs are normally blue in colour. This sign indicates the direction and distance to various destinations falling on that particular road. These signs are generally installed before intersections. This sign shows that direction and distance of the destination/place written on it. This sign board helps drivers in locating the places and thus is very helpful in saving time and fuel. This sign assures the driver that he is on right path and also tells the distance of the places written on it. This sign identifies the area. This sign tells that the limit of the particular area has started. This sign is illustrative on national highways. This sign indicates the availability of Telephone near road. : Informatory Road Signs | Transport Department, Government of Jharkhand
What are visual signs?
What are the visual signs? – Visual signs can take different forms. For instance, they can be a logo, a geometric figure, a photograph, graffiti, or traffic signs. Despite being in different forms, Charles Sanders Peirce, another founder of semiotics, classified signs into 3 types: Index, Icon, and Symbol.
What is difference between signs and symbols?
Meaning and context – A sign has a singular meaning. A symbol has multiple meanings, shifting with context. For example, the red colour is a “stop” sign in traffic, but a “fertility” symbol in Hinduism, and in China, while being indicative of the “devil”, “scarlet women” or “Santa Claus” in Christianity.
Was the lion and the chakra chosen as a sign of India, or symbol? Does it have a specific meaning or a contextual one? One is constantly reminded it is not just any lion, or any chakra, it is that of Ashoka, which connects it with the first historical empire of India, the Mauryan, and to a king who found peace in Buddhism after years of violence.
Did Ashoka see his symbols the same way as Indians did during the freedom struggle? Ashoka’s India was very different from India under the British Raj. He lived in times when Buddha’s body was never shown in art, but was represented as a lion (Sakyasimha or lion of sakya clan), or even as a wheel (Dhammachakka, or wheel of doctrine).
- Was the image on Ashoka’s pillar then that of the Buddha itself? Could the symbol then be construed as religious? Or was it imperial? Either way, why was it suitable for a secular republic? Two hundred years ago, historians did not know anything about Ashoka or Buddha.
- Ashoka tales were found in folktales and legends.
And Buddha was at best the ninth avatar of Vishnu as per some Hindu texts, but certainly not a popular sage or god — at least not to European imperialists and colonisers who were slowly dominating the world with their new technologies. It was the rise of the subjects such as archaeology and philology, that led a great interest in ancient history and the discovery of Ashoka’s inscriptions and Buddhist manuscripts, that told the world of a revolutionary philosopher who lived five centuries before Jesus Christ and an emperor who lived shortly after Alexander the Great, who spoke of his subjects as his children, and expressed remorse over past violence.
What information is shown in a red triangle?
Which Is More Dangerous: Red, Yellow Or Blue Black Road Signs? Brush Up With Our Guide Let’s be honest: the Highway Code probably isn’t imprinted in your mind in quite the way it should be. If you’re older than 35, you didn’t have to take a theory test to get your driving licence. Or perhaps you did take it, but that knowledge is now a distant memory.
- Maybe your test is coming up, and you think things like just aren’t that important But if you know how to interpret signs instinctively, navigating the roads becomes easier than ever before.
- Luckily, we’re here to give you some simple hacks to understanding the highway.
- If you know what to expect, there will be fewer surprises while you’re behind the wheel.
Road signs are colour-coded, and the shapes are here to help you get the message at a glance. Circles = orders Red circles = prohibitions If you see a circular sign with either a red ring or circle, it’s telling you to stop, slow down, not enter or do some other kind of activity.
- These are regulatory signs, so include speed limits (the number will be the maximum speed) and signs which prohibit types of vehicle on a certain road – e.g.
- A circular sign with a red ring and a picture of a horse being ridden, it means that no accompanied horses are allowed to continue.
- Blue circles = instructions Blue circular signs give a positive instruction.
They often feature arrows, instructing drivers to follow the direction suggested. Examples of this type of sign include mini-roundabout signs, one-way traffic signs, and keep left or right signs. Triangles = warnings Triangle signs – usually white with a red border – are here to let you know that you’re approaching a hazard or a place to stop.
They will usually point upwards and feature an image of the hazard: merging traffic, a junction on a bend, a slippery road or a zebra crossing are all examples of common warning road signs. An exclamation mark in a triangular sign means ‘other danger’ and will describe the hazard on a white sign below – a hidden dip will be presented like this, for example.
EXCEPTION : While most triangular signs are warnings, not all warnings are triangular. Red rectangles contain warnings, too – so watch out for these particularly if you’re in an area you don’t know well. Rectangles = information and directions Blue rectangles = information or motorway directions Most blue rectangular signs indicate a motorway.
- They will often feature directions, distances to destinations, or some other information such as distance until a junction.
- It’s important to identify motorways from other roads, as other driving laws apply to these kinds of road.
- Green rectangles = directions on primary routes These signs provide directions on primary routes – also known as A-roads.
Destination names will be in white, while the route numbers will be in yellow. White rectangles = directions on non-primary routes Roads that are neither motorways nor primary routes will feature white direction signs with black lettering. If you’re expecting to be on a primary route and see one of these signs – think about checking your Sat-Nav! Brown arrow signs = tourist destinations Popular destinations are shown on brown signs with white writing.
They are shown using either symbols or words – an elephant symbol will mean zoo, for example. The signs also usually show direction and distance. Exceptions Black sign with white chevrons These signs are typically found on bends or some roundabouts. Depending on whether it points left or right, this sign indicates a sharp bend in the direction in points.
This would usually be seen on a blue sign, but its difference indicates that the bend is sharper, or that it is in a place where a larger, more obvious sign is needed (such as a national speed limit road). Yellow signs = emergency diversions or temporary checks Small yellow signs show traffic diversions.
These are often temporary signs, but in case of longer-term diversion, a small yellow symbol can be added to a larger directions sign. A symbol is attached to each diversion – a black diamond shape on a yellow background, for example – to ensure that you are following the correct diverted route. Yellow signs can also be used as temporary signs for vehicle checks.

What does a hump sign mean?
High visibility speed hump signs – A caution speed bump, or speed bump, sign is essential for any area using speed bumps as a traffic calming measure. The Highways (Road Humps) Regulations 1999 also outlines the importance of displaying traffic signs to warn road users of road humps.
- A speed hump ahead sign indicates to drivers that they will need to slow their speed down.
- We even supply speed hump limit signs to specify a speed limit to drivers.
- Using a highly durable, highly reflective material ensures these speed bump road signs will stand the test of time and are visible to drivers.
Simply mount with one of our speed bump sign posts or onto the wall. You’ll find traffic hump warning signs are vital in ensuring traffic calming areas remain safe and prevent potential accidents from speeding vehicles. For a complete traffic calming solution, why not take a look at our range of speed bumps, speed cushions and flow plates.
What is the sign for no waiting?
Can I park on a single yellow lines? – Single yellow lines mean no waiting or parking during the times shown on nearby signs or at the entrance to a controlled parking zone. There are no standard times or rules so you must always check the signs before waiting or parking.
- You can usually stop to drop off or pick up passengers unless signs say otherwise or there are small yellow lines marked on the pavement at right angles to its edge.
- If these yellow markings are in pairs, it means no loading or unloading at any time – if they’re single markings, check the signs for what you can and can’t do.

What is the T junction sign?
A ‘T-Junction’ sign is a warning sign typically found before the intersection of two roads that are going in different directions, with one road passing over the other. The ‘T’ shape is shown indicates that you need to be careful when crossing a T-junction.
