Question 3740
A traffic light with one or two flashing red lights temporarily prohibits vehicles from proceeding...
- because of a crash.
- because of roadwork on the roadway.
- because of fire trucks exiting a fire station.
Show answer and explanation
Correct answer: because of fire trucks exiting a fire station.
One flashing red light, or two red lights flashing alternately, mean you must not proceed until they go out. They are used at railroad crossings, movable bridges and pontoon ferries, at fire station exits and where aircraft fly low, not for roadwork or crashes. In the image, a fire truck is leaving the station.
