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

💡 On a one-way street, you may pass on either side of slower traffic (when lanes allow).

Why Road Signs Matter on the DMV Test
Road signs make up one of the largest sections of every state's written knowledge exam, and for good reason: signs are the language drivers use to communicate. In the United States, traffic signs are standardized by the federal Manual on Uniform Traffic Control Devices (MUTCD), published by the Federal Highway Administration. That is why a stop sign looks the same in Florida as it does in Oregon - the shape, color, and meaning are set by a single national standard. Learning that standard is the key to answering sign questions correctly, even for signs you have never seen before.
Read a Sign by Its Shape and Color
The MUTCD system is built so you can understand a sign before you even read the words on it. An octagon always means stop. An upside-down triangle always means yield. A diamond always warns of a hazard ahead. Red means stop or prohibition, yellow means general warning, orange means a work zone, and green gives you guidance and directions. Master these shape-and-color rules from the categories above and you can decode almost any sign on the test.
Practice Until Recognition Is Automatic
Knowing what a sign means and recognizing it instantly at 55 mph are two different skills. The DMV test - and real driving - rewards instant recognition. Our visual road signs practice test shows you the actual sign and asks what it means, which is exactly how the recognition skill is built. When you can name every sign in this guide without hesitating, you are ready. From there, put it all together with a full state permit practice test or review the rules of the road in our guide to right-of-way.
