Passing target: 80% (24/30)
Late at night, the traffic signal facing you shows a flashing yellow light. The cross street has a flashing red light. What should you do?
Two enlarged signal displays are labeled Facing you and Cross street. The facing signal has a yellow middle lamp flashing; the cross-street signal has a red upper lamp flashing.
Correct answer: Slow down, watch for cross traffic and pedestrians, and go on with caution.
Why
Signals often switch to flashing mode late at night when traffic is light. The driver with the flashing red must stop and yield, but at night that driver may be tired or impaired. Cover the brake and be ready to stop if another vehicle enters.
