Traffic Signs and Their Meanings

9 Traffic Signs and Their Meanings

Whether you are studying for your driver’s exam or saw an unusual sign that you do not remember, it is always a good idea to familiarize yourself with it. Recognizing traffic signs and knowing their meanings can help drivers make safe driving decisions faster and more easily.

Here are 9 popular traffic signs and their meanings:

1. Deer Crossing Signs

Deer Crossing Sign

This road warning sign is not an opportunity to ask why the deer crossed the road. As defined by the Manual on Uniform Traffic Control Devices (MUTCD) by the Federal Highway Administration, the MUTCD W11-3 deer crossing sign alerts drivers to areas where the population of deer is active and may enter the roadway.

An average white-tailed deer, which is common throughout North America, weighs around 100 pounds and is about three or four feet tall.
Seeing a deer of this size on the road is a very serious situation, and as a warning, deer crossing signs can help drivers pass safely through these areas.

2. Keep Right Signs

Keep Right Sign

When a road narrows, due to dividers or other obstructions, drivers need to be made aware of the change in the path of the roadway.

MUTCD R4-7 and MUTCD R4-8 are the “keep right” and “keep left” versions of the same obstruction warning. These regulatory traffic signs aid in the flow of vehicles when these slight obstacles are present.

3. Men at Work Signs

Men at Work Sign

MUTCD W21-1 is a temporary warning sign used to alert drivers of upcoming road work. Orange is used on this sign because it is one of the most visible colors to the human eye, and can be noticed above other traffic signs on the road.

When driving through work zones, safe driving is at its highest premium. Men at work signs are generally accompanied by other temporary warning signs, such as “Road Work Ahead” and “Detour” signs.

4. No Bicycle Signs

No Bicycle Signs

Bicycle riders are subject to many of the same traffic control signs that drivers are on the roadways.
No bicycle signs, MUTCD R5-6, prohibit bicycle traffic from entering a roadway or facility. If used at a facility, these signs should be posted at the entrances.

Other bicycle-related traffic signs are No Parking Bike Lane Signs (MUTCD R7-9) and Bicycle Warning Signs (MUTCD W11-1).

5. No U-Turn Signs

No U-Turn Sign

There are a few variations of a no U-turn sign, but the example shown here is the official MUTCD version (MUTCD R3-4).

With the curved arrow showing a U-turn and bold prohibition symbol over it, this standard design is understood to express areas where drivers cannot change the direction of their vehicle into the opposite direction.

6. Pedestrian Crossing Signs

Pedestrian Crossing Sign

There are a few MUTCD versions of pedestrian crossing signs that are posted near crosswalks and intersections. MUTCD W11-2 is used in a majority of settings and is pictured here

MUTCD S1-1 is a Pedestrian School Area Sign and is posted in school zones. Both signs use a yellow-green fluorescent reflective sheeting that enhances its visibility on the roads.

7. Speed Limit Signs

Speed Limit Sign

Speed limit signs are essential traffic control signs and can vary in the limit depending on the specific state that you are driving through.
Often while driving through residential streets, speed limit signs may not be seen. This is because the speed limit for most residential areas is 25 miles per hour, and this law is understood by drivers who pass their driving exams.

Many highways have speed limits set at 55 miles per hour, but this can be changed by the state and will vary. Other common limits on highways are 45 miles per hour and 65 miles per hour.

8. Stop Signs

Stop Sign

Stop signs (MUTCD R1-1) are likely the most iconic of all traffic signs. Both the shape and color are important to how a stop sign is recognized and understood.
No other sign is of an octagon shape, and no other sign is red in color. This is done because of the importance a stop sign has on traffic safety.

Stop signs alert drivers to intersections and other areas where traffic may be traveling in opposite or crossing directions. For more information specifically about stop signs, visit our stop signs buyer’s guide.

9. Yield Signs

Stop Sign

Yield signs (MUTCD R1-2) are similar to stop signs, but used in less dangerous situations. Used at passive cross streets or traffic circles, yield signs help to keep traffic flowing, while still allowing drivers from different directions to pass through.

The yield sign symbol is often used with Pedestrian Crossing Signs where it is the state law to yield to pedestrians in the crosswalk. They can also be found on In-street Crossing Signs.

Knowing these popular traffic signs and their meanings is a vital part of being a safe driver, bicyclist, and pedestrian.
