If you are driving in front of a vehicle that wants to pass, what should you do?

Answer: C — Signal and move to the right

When a vehicle wants to pass you, it is important to signal and move to the right lane to allow them to safely pass. Staying in your lane (option A) or increasing your speed (option B) can prevent the other vehicle from passing and potentially cause an accident. Making eye contact with the driver (option D) may not always be possible or effective in communicating your intentions to the other driver. Therefore, the best option in this scenario is to signal and move to the right lane.
