A bus must stop at least how many feet before the draw of a drawbridge without a signal light or an attendant?

A bus is required to stop at least 50 feet before the draw of a drawbridge when there is no signal light or attendant present. This regulation is in place to ensure the safety of the passengers and the driver, as bridges can be raised unexpectedly and it is crucial to prevent buses from being caught on the bridge itself or in potential danger when it is in the process of opening.

Stopping 50 feet away allows adequate space for the driver to assess the situation and take necessary actions, ensuring the safety of the bus and its passengers. Knowing and adhering to this distance is essential for compliant driving in areas with drawbridges.
