Which statement is true regarding a solid yellow signal ahead?

• A. Prepare to stop
• B. Proceed through with caution
• C. Accelerate to clear the intersection
• D. Ignore the signal and proceed

Answer: (A)

A solid yellow signal ahead warns that the light is about to turn red, so you should slow down and prepare to stop before the intersection. Stop if you can do so safely; if you’re too close to stop in time, continue with caution to clear the intersection rather than slamming on the brakes. This is why preparing to stop is the best course of action. Accelerating to race through the intersection, ignoring the signal, or proceeding without caution are unsafe and not appropriate responses to a solid yellow light.
