How far away should an oncoming vehicle be before passing a slow vehicle on a two-way road?

When passing a slow vehicle on a two-way road, it is crucial to ensure that an oncoming vehicle is at least 10-12 seconds away. This distance allows ample time to complete the passing maneuver safely while maintaining an adequate buffer against potential collisions.

The 10-12 seconds distance ensures that you have sufficient time to assess the oncoming traffic, gauge your speed, and execute the pass without rushing. Calculating this distance based on typical speeds means that the approaching vehicle is far enough for you to confidently pass without putting yourself or others in danger.

This standard not only prioritizes safety but also aligns with traffic regulations designed to reduce accidents in situations where visibility and reaction times are critical. It also allows for the driver to consider factors such as the speed of the oncoming vehicle and the length of the vehicle being passed, ensuring that the entire maneuver is completed without interfering with oncoming traffic.
