How must a driver handle a flashing red traffic light?
- Make a complete stop, then proceed as at a stop sign when safe
- Slow down and continue without stopping
- Wait for the signal to become solid green before moving
- Stop only if cross traffic is approaching
Answer: Make a complete stop, then proceed as at a stop sign when safe. A flashing red indication uses the stop-sign procedure. The driver stops behind the stop line, crosswalk, or intersection, looks both ways, and proceeds only after yielding when required. Merely slowing leaves the required stop undone. Waiting for a solid green treats the signal as if it were a normal red light and may create unnecessary delay. Stopping only for visible traffic is also incomplete. Remember: flashing red means full stop, search, and yield.
