When is it illegal to pass another vehicle?

Passing another vehicle is illegal in no passing zones and when approaching intersections due to safety concerns. No passing zones are designated areas where it is unsafe to overtake another vehicle, typically due to limited visibility, curves in the road, or the proximity to intersections. In such zones, attempting to pass could create dangerous situations not only for the driver attempting to pass but also for oncoming traffic and other vehicles.

When approaching intersections, the likelihood of encountering pedestrians, turning vehicles, and changing traffic conditions increases, making it critical for drivers to refrain from passing to ensure everyone’s safety. These rules are in place to maintain safe road conditions and reduce the risk of accidents.

The other options do not reflect the legal restrictions associated with passing vehicles. Passes during daylight hours can be legal if done in the appropriate zones. The speed limit being below 30 mph does not inherently restrict passing, as it may be legal within marked areas. Lastly, the fact that other drivers are passing does not provide grounds for any pass to be deemed illegal and could create confusion if one were to try to mimic others without understanding the regulations in place.
