Regulatory signs state traffic laws, and you must obey them. Most are black on white rectangles, but the two most important, STOP and YIELD, have shapes no other sign uses.

Stop
Stop sign

Know the rule

The stop sign is the only 8-sided sign (white letters on red). Make a complete stop at the stop line; with no stop line, before the crosswalk; with neither, before entering the intersection. Yield and stay stopped until it is safe.

Handbook p. 21 ↗
Yield
Yield sign

Know the rule

The yield sign is the only 3-sided sign (red letters on white). Slow down, look left and right, and yield to pedestrians, bicycles and vehicles. Proceed only when you can do so safely.

Speed limit
Speed limit sign

Know the rule

A black-on-white rectangular speed limit sign gives the maximum speed for the part of the road where it is posted.

Handbook p. 21 ↗

Two-way left turn sign

Vehicles traveling in either direction can use the center lane to turn left.

Handbook p. 21 ↗

One Way sign

Traffic can only go in the direction of the arrow.

Handbook p. 21 ↗

High Occupancy Vehicle (HOV) sign

You may use the lane only if your vehicle has the number of people marked on the sign.

Handbook p. 21 ↗
HOV lane
HOV 2+ lane sign

Know the rule

Reserved parking signs mark spaces for people with disability parking permits.

No turn on red
No Turn On Red sign

Put it into practice

You're driving alone and see an HOV 2+ ONLY lane. You may not use it: the sign requires at least 2 people in the vehicle.

Check your understanding

Read the question, decide on an answer, then open it to check the explanation. These are Roadwise study questions based on the source handbook.

At a stop sign with no stop line and no crosswalk, where must you stop?
  1. Exactly at the sign itself
  2. Wherever you can see cross traffic best
  3. You do not need to stop if no traffic is present
  4. Before entering the intersection

Answer: Before entering the intersection

Without a stop line or crosswalk, you must stop before entering the intersection.

Handbook p. 21 ↗
At a yield sign, what should you do?
  1. Slow down and yield to all road users
  2. Come to a complete stop every time
  3. Proceed without slowing since it's not a stop sign
