What should you not do when dealing with a tailgater?

Answer: B — Flash your taillights to signal a stop

When determining how to handle a tailgater, it is important to prioritize safety and effective communication on the roadway. Flashing your taillights to signal a stop is not advisable in this situation. This action can be misinterpreted or could even lead to a rear-end collision, as the tailgater may not have enough time to react appropriately. Instead, maintaining a safe following distance and signaling a lane change are more effective strategies to alleviate the situation with a tailgater. Additionally, changing speeds dramatically can confuse the driver behind you and increase the risk of an accident. The most appropriate approach to dealing with a tailgater is to remain calm, maintain a steady speed, and, if safe, change lanes to allow the driver behind you to pass. This helps to reduce the tension and potential risk associated with a tailgater.
