How far should you stop from a railroad crossing with flashing lights?

Answer: B — 15 feet

When approaching a railroad crossing with flashing lights, the law requires drivers to stop at least 15 feet away from the tracks. This distance ensures that you are safely positioned behind the stop line, allowing for an adequate buffer zone while ensuring visibility and minimizing the risk of an accident. Stopping at this distance gives you enough space to react to any approaching trains and to observe the tracks for any other hazards. Additionally, it complies with safety regulations designed to protect both drivers and pedestrians near railroad crossings.
