When starting a bus on a level surface with good traction, what is often unnecessary?

When starting a bus on a level surface with good traction, slow acceleration is often unnecessary because the bus is not likely to lose traction or skid. On a level surface, the combination of good road conditions and the weight distribution of the bus allows for a more controlled and stable start. Therefore, the driver can apply the accelerator with a bit more confidence, potentially allowing for a quicker departure without the concern of slipping or losing control.

In this scenario, using the parking brake is important to ensure that the bus remains stationary until the driver is ready to move, and checking tires or conducting visual inspections are critical safety protocols that should always be followed to ensure the vehicle is roadworthy and to prevent potential tire blowouts or other related issues.
