Why is it important for a bus driver to check their tire pressure regularly?

Answer: B — To ensure safety and fuel efficiency

Regularly checking tire pressure is crucial for a bus driver primarily to ensure safety and fuel efficiency. Properly inflated tires provide optimal traction and handling, which are essential for preventing accidents and maintaining control of the vehicle, especially under challenging driving conditions. Under-inflated tires can lead to increased rolling resistance, making the engine work harder and, consequently, consuming more fuel. This can also increase the risk of tire blowouts, which can be catastrophic when operating a large vehicle like a bus. Therefore, maintaining the correct tire pressure not only contributes to the safe operation of the bus but also enhances its efficiency on the road, benefiting both passengers and the environment. The other factors, while significant in their own right, do not encompass the full safety and operational implications that proper tire pressure checks provide.
