Put it into practice

You stop at a stop sign with a plaque reading CROSS TRAFFIC DOES NOT STOP. Drivers on the cross street won't be stopping for you. Wait for a safe gap in both directions before you go.

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.

What does a supplemental plaque below a stop sign typically indicate?
  1. An advisory speed for the intersection
  2. Which directions of traffic must stop
  3. A detour route around road work
  4. A weight restriction for trucks

Answer: Which directions of traffic must stop

Supplemental plaques are added below stop signs to indicate which directions must stop.

Handbook p. 37 ↗
A "CROSS TRAFFIC DOES NOT STOP" plaque under a stop sign means every direction at that intersection must stop.
  1. True
  2. False

Answer: False

Supplemental plaques show which directions must stop; CROSS TRAFFIC DOES NOT STOP means the cross street does not stop for you.

Handbook p. 37 ↗
A stop sign has an "ALL WAY" supplemental plaque beneath it. What does the plaque tell you?
  1. Only cross traffic must stop
  2. Traffic from every direction must stop
  3. You may turn in any direction
  4. Every lane must turn at the intersection

Answer: Traffic from every direction must stop

Supplemental plaques under stop signs show which directions must stop; ALL WAY means every approach to the intersection has a stop sign.

Handbook p. 37 ↗
What kind of information do traffic guidance signs give drivers?
  1. Speed limits and turn prohibitions
  2. Road type, upcoming exits, and distances
  3. Upcoming hazards and road conditions
  4. Temporary construction conditions

Answer: Road type, upcoming exits, and distances

Traffic guidance signs tell drivers the type of road they are on, upcoming highway entrances and exits, and distances to destinations.
