Which statement about red flashing lights is correct?

• A. Stop and go immediately
• B. Stop and wait until safe to proceed
• C. Proceed with caution without stopping
• D. Turn right away

Answer: (B)

Red flashing lights indicate a hazard and require a full stop. You must come to a complete stop and wait until the lights stop flashing and the way is clear before proceeding. This rule protects pedestrians and other vehicles that may be in or approaching the intersection or crossing. You should only move once you can do so safely after the signal is no longer flashing. The other options would involve moving despite a known hazard, which is not allowed.
