Question: 1 / 400

How are service brakes activated on a bus?

By the emergency braking system

By the driver pushing a knob

By the driver's pressing on the brake pedal

The service brakes on a bus are activated when the driver presses on the brake pedal. This action engages the hydraulic or air brake system, allowing the bus to slow down or stop as needed. The service brakes are designed for regular stopping and are integral to safe driving, responding immediately to the driver's input.

Other methods mentioned, such as using an emergency braking system or a parking brake lever, serve different purposes. The emergency braking system is meant for situations where the regular brakes fail or when an urgent stop is required. The parking brake lever is intended to maintain the bus in a stationary position when parked and is not used for regular stopping during movement. The functionality of the service brakes is focused on the driver's ability to control the vehicle's speed effectively while driving.
