When another vehicle is about to overtake you, what should you do?

Moving to the right and allowing the other vehicle to pass is the appropriate action when being overtaken. This maneuver provides the overtaking vehicle with enough space to safely pass without any risk of collision. It also promotes smoother traffic flow and enhances safety on the road. By yielding to the overtaking vehicle, you help prevent potential accidents that could occur if both vehicles try to occupy the same space at the same time.

The other choices could lead to dangerous situations. Pulling into the intersection might create confusion and could block the path of traffic, leading to a collision. Accelerating to avoid being passed can be hazardous, as it increases the speed differential and the risk of a crash, especially in situations where the overtaking driver is attempting to pass safely. Finally, using the horn to warn the driver does not address the situation effectively, and horn use can be misinterpreted as aggressive driving, potentially escalating tensions on the road.
