What should you do to improve safety if a vehicle is closely following you?

To improve safety when a vehicle is closely following you, changing lanes safely to let them pass is the most effective action. This maneuver allows the tailgating driver to overtake you, thereby eliminating the risk of a potential rear-end collision, which can occur if the driver misjudges the stopping distance. By moving to a different lane, you're promoting a safer driving environment not only for yourself but also for the following driver.

Additionally, increasing your speed can create a risky situation, especially if the road conditions are not suitable for speeding. Making an abrupt stop could lead to an unexpected hazard, risking the safety of other drivers behind you. Driving slower than the speed limit can also create confusion and may encourage tailgating or lead to other unsafe driving behaviors, as it disrupts the expected flow of traffic. Overall, allowing the following vehicle to pass in a safe manner is the best practice to enhance safety in this situation.
