If unsure about the sight distance for passing in a "No Passing Zone," what should a driver do?

In a "No Passing Zone," drivers are legally and safely instructed to not attempt to pass other vehicles. These zones are typically marked to indicate limited visibility or potential hazards that make passing dangerous. If a driver is unsure about their sight distance while in such a zone, the safest action is to abort the attempt to pass. This decision minimizes the risk of accidents, as visibility could be blocked by curves, hills, or other obstacles, and any attempt to pass could lead to a head-on collision with oncoming traffic. Prioritizing safety by not attempting to pass when visibility is questionable aligns with traffic laws and promotes responsible driving behaviors.
