When is passing on a two-lane road prohibited?

Passing on a two-lane road is prohibited when it is within 100 feet of a railroad crossing because this rule is designed to ensure safety. Approaching a railroad crossing can pose a significant danger, as vehicles need to be aware of potential oncoming trains and stop in a timely manner. When a driver is too close to the crossing, visibility of both oncoming trains and the road ahead can be compromised. Additionally, being in the act of passing could result in a situation where a vehicle is unable to stop safely in time for an approaching train. Thus, this regulation helps prevent accidents and promotes safer travel on roadways that intersect with railroads.
