What must you do when another vehicle is about to overtake and pass your vehicle?

When another vehicle is about to overtake and pass your vehicle, the appropriate action is to move to the right and allow the other vehicle to pass. This maneuver is a demonstration of safe driving practices and helps maintain smooth traffic flow. It shows courtesy to the other driver, allowing them to proceed without undue delay.

By giving the other vehicle space to pass safely, you reduce the risk of accidents. Keeping to the right when being overtaken is not only a fundamental traffic rule but also enhances safety for all road users. It's important to ensure that this action is done in a controlled manner, without abrupt movements or sudden lane changes, to avoid unexpected situations.

The other actions mentioned may lead to confusion or unsafe driving conditions. Signaling the driver not to pass can create misunderstandings about your intentions and disrupt the flow of traffic. Moving left to block a vehicle from passing or speeding up to prevent passing can lead to aggressive driving behaviors and increase the likelihood of an accident. Adhering to the rule of allowing overtaking enhances safety on the road.
