Regulatory Signs - Laws You Must Obey
These signs have the force of law. Disobeying them is a traffic violation.
Yield Sign
Triangle (inverted)Red & White
Slow down and give the right of way to vehicles and pedestrians in the intersection. Stop only if necessary.
Unlike a stop sign, you do not need to stop if the way is clear.
Speed Limit Sign
Rectangle (vertical)White & Black
The maximum legal speed under ideal conditions. You must drive slower when conditions require it.
These are regulatory signs - exceeding the posted limit is always illegal.
Do Not Enter
CircleRed & White
You must not enter this road or lane. Usually found at one-way streets and highway ramps.
If you see this sign, you are about to drive the wrong way. Stop immediately.
Wrong Way
RectangleRed & White
You are traveling in the wrong direction on a one-way road or divided highway.
This sign appears together with 'Do Not Enter' on highway ramps.
One Way
RectangleBlack & White
Traffic flows in one direction only. All vehicles must travel in the direction of the arrow.
On a one-way street, you may pass on either side of slower traffic (when lanes allow).
No U-Turn
Circle with red slashRed, White & Black
U-turns are prohibited at this location.
U-turns are also prohibited wherever you cannot see 200+ feet in each direction.
Warning Signs - Hazards Ahead
Warning signs alert you to upcoming hazards or changes in road conditions. Slow down and prepare.
Curve Warning
DiamondYellow
A sharp curve is ahead. Slow down before entering the curve and check the advisory speed plate below the sign.
Many curve signs have an additional sign showing the recommended curve speed.
School Zone
Pentagon (5-sided)Yellow-Green
You are entering a school zone. When children are present, the speed limit drops to the posted school zone speed.
The distinctive pentagonal shape is used exclusively for school zone and school crossing signs.
Railroad Crossing
CircleYellow
A railroad crossing is ahead. Look both ways, listen for trains, and be prepared to stop.
The round shape is used exclusively for railroad advance warning signs - unique among warning signs.
Pedestrian Crossing
DiamondYellow
Pedestrians may be crossing the road ahead. Slow down and watch for people entering the road.
These are common near schools, parks, shopping areas, and residential neighborhoods.
Work Zone (Construction)
DiamondOrange
You are entering a construction or work zone. Obey reduced speed limits - fines are typically doubled.
Orange signs are exclusively used for construction/work zones and are temporary.
Slippery When Wet
DiamondYellow
The road surface becomes extremely slippery when wet. Reduce speed and increase following distance in rain.
This sign often appears on bridges, metal grating, and polished asphalt sections.
How to Read Any Road Sign on the Written Test
Sign questions turn up on every state's written knowledge exam - often as one of the single biggest categories - because signs are the shorthand drivers use to talk to one another. Nationwide, traffic signs follow one federal standard, the Manual on Uniform Traffic Control Devices (MUTCD), published by the Federal Highway Administration. A stop sign in Florida is identical to one in Oregon because that standard fixes its shape, color, and meaning. Learn the standard and you can answer sign questions correctly even when a particular sign is new to you.
Decode the Shape and Color First
The system is designed so a sign's shape and color reveal its purpose before you read a single word. An octagon is always stop; an upside-down triangle is always yield; a diamond always flags a hazard ahead. Red signals stop or prohibition, yellow a general warning, orange a work zone, and green directions and guidance. Lock in those shape-and-color cues from the categories above and most signs on the test become readable on sight.
Train Recognition Until It's Automatic
Understanding a sign and recognizing it in a split second at highway speed are two different skills, and the exam - like the road - rewards the second one. Our visual road signs practice test shows the sign and asks for its meaning, which is exactly how fast recognition is built. Once you can name every sign in this guide without pausing, you are ready. Then bring it together with a full state permit practice test or brush up on the rules in our guide to right-of-way.
