As a general rule, how many cars should you pass at once?

Answer: C — One car

When passing other vehicles, the general rule is to pass only one car at a time. This guideline is rooted in safety and proper control of your vehicle. Passing multiple vehicles at once can increase the risks for several reasons. Firstly, the maneuver requires a significant amount of space and time, especially at higher speeds. Passing more than one vehicle could lead to an inability to complete the maneuver safely, risking a collision with oncoming traffic or creating dangerous situations for other drivers. Additionally, when you pass just one vehicle, you maintain a clearer focus on the road conditions and the behavior of other drivers. It allows for better judgment regarding the speed of the vehicle you are passing compared to oncoming vehicles, making it easier to ascertain a safe distance to ensure a successful and safe pass. In summary, passing one car at a time helps to minimize risks and ensures greater control and safety on the road.
