Revision question · Environmental issues

After starting a bus with air brakes, what must you establish before moving off?

Revision material from the imported DVSA bank includes source-checked Lanekind learning corrections. These corrections are not newly issued official examination questions, and practice does not reproduce a live test paper.

Answer options

That opening the doors has removed the warning

That the parking brake has been released before pressure builds

That safe working pressure has built up and the brake checks pass

That revving the engine has made any warning acceptable

Show the answer

That safe working pressure has built up and the brake checks passThis was the right answer

Keep the bus secured and follow its handbook while air pressure builds. Do not move with unsafe brake pressure or a fault. The required engine speed depends on the vehicle; idling is not a universal pressure-building instruction.
