Every U.S. road sign you'll be tested on, grouped by category. Learn the shape, the color, and the exact meaning — then practice with real DMV-style questions.

Sign categories

Regulatory signs

Tell you the law: what you MUST do or MUST NOT do. Usually white rectangles with black text — except STOP (red octagon) and YIELD (red downward triangle). Disobeying one is a ticketable offense.

Examples

  • STOPSTOP

    STOP

    Come to a complete stop at the marked line, then proceed only when the intersection is clear.

  • YIELDYIELD

    YIELD

    Slow down and let traffic on the cross street pass. Stop only if needed to safely merge.

  • DO NOT ENTER

  • ONE WAY

    Traffic flows in the direction of the arrow only.

Frequently asked questions

How many DMV road sign categories are on the written test?

There are six core categories you need to know: regulatory, warning, guide, parking, school zone, and construction. Most state DMV written tests pull 8-15 sign questions from these categories.

What does the color of a road sign mean?

Color is a fast hint to the sign's purpose. Red = stop or prohibition. Yellow = general warning. Orange = construction zone. Green = direction or distance. Blue = motorist services. Brown = parks and recreation. Fluorescent yellow-green = pedestrian, bicycle or school zone.

What does the shape of a road sign tell you?

Shape works even when paint fades or snow covers the sign. Octagon = STOP. Triangle pointing down = YIELD. Diamond = warning. Pentagon = school zone. Rectangle (vertical) = regulatory. Rectangle (horizontal) = guide. Round = railroad crossing.

Are road signs the same in every U.S. state?

Yes — U.S. road signs follow the federal Manual on Uniform Traffic Control Devices (MUTCD), so a STOP sign in California means exactly the same as a STOP sign in New York. State-specific signs are limited to local guide information.

How many road sign questions are on the DMV written test?

It varies by state, but you can expect 25-40% of the written test to be about signs — roughly 6 to 20 questions depending on whether your state uses a 20, 30, 46 or 50-question test.

What happens if I disobey a regulatory road sign?

Disobeying a regulatory sign (STOP, YIELD, ONE WAY, NO U-TURN) is a moving violation. Expect a $100-$400 fine, points on your license, and an insurance premium hike for up to 3 years.

Where can I practice DMV road sign questions for free?
