How should you respond if a vehicle is tailgating you?

Answer: B — Change lanes when safe to do so

When dealing with a tailgating vehicle, changing lanes when it is safe to do so is the most appropriate response. This action allows you to move out of the way of the aggressive driver, thereby reducing the risk of a rear-end collision. Tailgating indicates that the driver is either impatient or inattentive, and by shifting lanes, you can create additional space and reduce stress for both yourself and the tailgater. Additionally, speeding up to create distance may increase the chances of an accident if the tailgater misjudges their distance and continues to follow too closely. Braking suddenly is dangerous and could escalate the situation, potentially leading to an accident. Lastly, ignoring the tailgater and continuing to drive without taking any action does not address the immediate safety concern and could keep you in a precarious situation. Thus, safely changing lanes is the best and most strategic course of action.
