What action should you take if you notice a vehicle is not yielding while you are signaling to change lanes?

Answer: B — Yield and wait until it is safe

When you notice a vehicle is not yielding while you are signaling to change lanes, the safest and most responsible action is to yield and wait until it is safe. This approach prioritizes safety for all road users, allowing you to assess the situation clearly before completing your lane change. Failing to yield can lead to accidents or collisions, especially if the other driver does not see your signal or is unable to adjust their speed. By waiting until it is safe, you ensure that you have adequate space and time to change lanes without causing disruption or danger to yourself or others. This practice aligns with defensive driving principles, which emphasize awareness, caution, and making decisions that prevent potential hazards on the road.
