The length of a school bus can vary depending on the type of bus, but here's a general guideline:
Full-sized school bus: 40 feet (12.2 meters) long. This is the most common type of school bus in the United States.
Medium-sized school bus: 30-35 feet (9.1-10.7 meters) long. These buses are often used for shorter routes or in areas with narrower roads.
Small school bus: 20-25 feet (6.1-7.6 meters) long. These buses are typically used for transporting students with special needs or for very short routes.
