What is the safe distance for passing another vehicle on the left?

When passing another vehicle on the left, it's essential to ensure there is sufficient visibility and room to do so safely. The correct answer emphasizes that a driver should not attempt to pass within 200 feet of an approaching vehicle. This distance helps avoid dangerous situations where two vehicles may be in close proximity and potentially collide if one is overtaking the other while the other is approaching.

Maintaining this buffer allows for a clearer line of sight and ensures that the driver has time to complete the maneuver without interfering with the oncoming traffic. It emphasizes proactive decision-making to enhance safety on the road. By keeping this distance, drivers can better assess the situation and ensure they won't be caught in a situation where they have to abruptly end their pass, which could lead to serious accidents.

While other distances related to intersections, curves, and railroad crossings are important safety considerations, the specific guideline regarding the approaching vehicle is particularly critical in preventing head-on collisions during a passing maneuver.
