What is the approximate height and width of a school bus?

The correct choice reflects the typical dimensions of a standard school bus. School buses are generally designed with a height of about 10 feet and a width of approximately 8 feet. This size allows for ample interior space to accommodate students safely, while also ensuring that the bus remains within regulations for roadways and bridges.

The dimensions specified in other choices do not correspond with standard school bus sizes. For instance, an 8' height may result in inadequate overhead clearance, especially at bus stops or transit points. Similarly, a width of 6 feet is narrower than the standard, which could present safety concerns as it does not provide enough space for children to enter and exit safely. Lastly, a height of 12 feet is excessively tall, which would create challenges when navigating under bridges or through low-clearance areas, making it impractical for typical road use. Thus, the dimensions of 10' by 8' are appropriate for maintaining both safety and compliance with transportation regulations.
