How many feet of overhead clearance does a school bus need?

A school bus typically requires a minimum of 14 feet of overhead clearance to safely navigate under bridges, power lines, and other structures. This clearance ensures that there is enough space for the bus, which is about 10 to 12 feet tall, while allowing for any additional obstructions such as cargo or snow on the roof. Proper clearance is crucial for safety and to prevent accidents.
