How far must you stop from a school bus with its stop arm extended?

When you see a school bus with its stop arm extended, the law requires you to stop your vehicle at least 20 feet away from the bus. This distance is crucial for ensuring the safety of children who may be entering or exiting the bus. Stopping at this distance allows for adequate space between your vehicle and the bus, reducing the risk of accidents. Children may be unpredictable as they approach or leave the bus, so providing enough distance is essential for their safety.

The other distances provided do not meet the legal requirement for stopping near a school bus. If you were to stop at 10, 15, or 25 feet, you may either be too close to the bus, which could endanger the children, or unnecessarily far beyond what is required. Adhering to the 20-foot rule ensures compliance with traffic laws and contributes to a safer environment for students.
