What does a flashing red traffic light mean?

A FLASHING RED light means STOP completely, then proceed when it is SAFE — treat it exactly like a STOP SIGN. DMV/permit rules of the road. Come to a full stop, yield to other traffic and pedestrians, and go when the way is clear. COMPARE: a FLASHING YELLOW light means SLOW DOWN and proceed with CAUTION (you don't have to stop, but be alert). Flashing signals are often used at intersections during off-peak hours or where a normal signal isn't warranted. Knowing flashing red = stop (like a stop sign) and flashing yellow = caution is commonly tested.
