When is it illegal to pass another vehicle in relation to an intersection or railroad crossing?

Answer: C — Within 100 feet

It is illegal to pass another vehicle within 100 feet of an intersection or railroad crossing due to safety concerns. The rationale behind this regulation is to ensure that drivers have adequate visibility and reaction time when navigating these potentially hazardous areas. Intersections and railroad crossings often involve complex traffic situations where vehicles may be stopping, turning, or approaching from multiple directions. Passing another vehicle too close to these areas could lead to increased risks of accidents, as the flow of traffic can change suddenly. By establishing a distance of 100 feet, the law aims to provide a safer environment for all road users, allowing for clear sightlines and preventing surprises that could result from a vehicle unexpectedly passing another. This distance serves as a buffer, ensuring that drivers can make safe, informed decisions in situations that could easily lead to collisions if someone were to attempt to pass at the wrong moment.
