What should you do when approaching a traffic control signal that is not working?

Proceed through the intersection without reducing speed.
Treat it as a yield sign and proceed without stopping.
Treat it as a caution sign and proceed with caution.
Treat it as a stop sign and proceed when it is safe.

The correct answer is: Treat it as a stop sign and proceed when it is safe.

When approaching a traffic control signal, you should always follow the signal's instructions. In this case, if the signal is not working, it is best to treat it as a stop sign and proceed only when it is safe to do so. Option A is incorrect because you should never proceed through an intersection without reducing speed, regardless of the signal's status. Option B is also incorrect because treating the signal as a yield sign means you must come to a complete stop if necessary, and only proceed when it is safe to do so. Option C is incorrect because treating the signal as a caution sign does not require you to come to a complete stop, but you must still proceed with caution. The only option that aligns with traffic laws and safety guidelines is D, treating the signal as a stop sign.
