Sign shape and color tell you the kind of message before you can read it. Regulatory signs state the law at that spot, and disobeying one is a traffic violation.

Know the rule

Regulatory signs are black or red on a white background.

Handbook p. 10 ↗

Know the rule

Speed limit signs show the maximum or minimum speed allowed. Maximums are for ideal conditions; slow down when conditions require it.

Stop
Stop sign

Know the rule

At a stop sign, come to a complete stop at the marked stop line. If there's no line, stop before the crosswalk on the near side; if none, where you can see approaching traffic, nearest the crossing road.

Know the rule

Prohibited signs show something you cannot do, such as no U-turn or no left turn.

You approach a stop sign with no painted stop line and no crosswalk. Stop at the point nearest the crossing road where you can see approaching traffic.

  1. Anywhere before entering the intersection
  2. Exactly at the stop sign post
  3. At the point nearest the intersecting roadway where you have a view of approaching traffic
  4. At least 50 feet before the intersection

Handbook p. 10 ↗
What must you do at a sign posted with a yield symbol?
  1. Stop only if other vehicles are visible
  2. Come to a full stop every time
  3. Speed up to merge quickly
  4. Slow or stop and yield to those with the right-of-way

  1. Police, highway workers or crossing guards

  4. Only uniformed police officers

Answer: Police, highway workers or crossing guards
