Führerschein Führerscheintest Klasse D — Busse 3

Question 1

What must a bus driver do if a passenger becomes seriously ill during a journey?

Accepted Answer

Stop safely as soon as possible, call emergency services, and provide first aid

Answer

A medical emergency requires immediately stopping the vehicle safely, calling 112, and rendering first aid — passenger welfare takes absolute priority over the schedule.

Question 2

How does the turning radius of a bus differ from that of a car, and what hazard does this create?

Accepted Answer

A bus has a much larger turning radius and the rear overhang swings outward during turns, creating a hazard for pedestrians

Answer

A bus's rear overhang sweeps outward (tail swing) during turns, which can strike pedestrians or cyclists on the footpath even when the front of the bus has cleared the corner.

Question 3

What is 'brake fade' and why is it especially dangerous for bus drivers on mountain descents?

Accepted Answer

Brake fade is the reduction in braking effectiveness due to overheating, which can cause total brake failure on long descents

Answer

Overheating from continuous braking on long descents reduces hydraulic brake effectiveness; bus drivers must use engine braking and retarders to prevent this.

Question 4

What does the 'dead man's handle' or automatic stop system do on modern buses?

Accepted Answer

It automatically applies the brakes and stops the bus if the driver becomes incapacitated

Answer

A dead man's handle or driver monitoring system automatically halts the vehicle safely if the driver is detected as incapacitated, protecting passengers and other road users.

Question 5

Under what conditions is a bus driver permitted to allow standing passengers?

Accepted Answer

Only when the vehicle is type-approved for standing passengers and only on routes where this is permitted

Answer

Standing passengers are only permitted in vehicles specifically designed and approved for this purpose, and only on local/urban routes where such carriage is authorized.
