What does a flashing yellow signal mean?

• A. Proceed with caution and be prepared to slow or stop for pedestrians or other traffic.
• B. Stop immediately.
• C. Go at normal speed with no caution.
• D. Only turn left.

Answer: (A)

A flashing yellow signal is a warning to slow down and stay alert. It means proceed with caution and be prepared to slow or stop for pedestrians or other traffic. The idea is to reduce speed and carefully scan the intersection and surrounding area for any crossing pedestrians, bicyclists, or vehicles that might not be stopping or yielding as you would at a full stop or green light. You don’t have the right of way to go through freely, but you don’t necessarily have to stop unless conditions require it.

This isn’t telling you to stop immediately, nor to go at normal speed without caution, nor to make only a left turn. Those options ignore the warning to watch for hazards and adjust your speed and attention accordingly.
