When is passing a vehicle permitted?

Passing a vehicle is permitted when it can be done safely. This means the driver must ensure that there is adequate space to pass without endangering themselves or others on the road. Prior to attempting a pass, it's essential for a driver to check for oncoming traffic, to make sure there are no obstacles, and to confirm that the maneuver can be completed efficiently and without risk. Ensuring safety is the top priority when passing, which includes using turn signals to indicate your intentions to other drivers.

In contrast, the other scenarios do not align with safe driving practices. For instance, passing just because another vehicle is in front does not consider the surrounding conditions and can lead to unsafe situations. Similarly, passing whenever there is a clear road ahead ignores the importance of assessing the situation for safety, such as the speed of the vehicle being overtaken and the distance required to complete the maneuver. The idea of never being allowed to pass is not practical in driving and would hinder efficient travel.
