What should you do after overtaking a vehicle?

Answer: B — Look in your rearview mirror

After overtaking a vehicle, it is crucial to look in your rearview mirror to ensure that you have safely cleared the vehicle you just passed. This action allows you to confirm that there is enough distance between your vehicle and the one you overtook, helping to prevent any possible collisions or misunderstandings about your position on the road. Monitoring the rearview mirror also enables you to be aware of any vehicles approaching from behind, which is essential for maintaining road safety as you make decisions regarding lane changes or merging back into your original lane. This practice reinforces safe driving habits and is a fundamental part of defensive driving. The other choices suggest actions that could compromise safety. Turning off your rear indicator immediately without checking your surroundings can lead to confusion for other drivers. Accelerating to gain distance quickly may increase the risk of losing control or misjudging the distance. Changing lanes without signaling is dangerous, as it does not communicate your intentions to other drivers, potentially leading to accidents.
