Führerschein Führerscheintest Klasse D — Busse 3 — Questions and Answers
Question 1: What must a bus driver do if a passenger becomes seriously ill during a journey?
- Stop safely as soon as possible, call emergency services, and provide first aid (Correct answer)
- Continue to the next scheduled stop before calling for help
- Ask other passengers to assist without stopping
- Radio the depot and await instructions before stopping
Correct answer: Stop safely as soon as possible, call emergency services, and provide first aid
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?
- A bus has a much larger turning radius and the rear overhang swings outward during turns, creating a hazard for pedestrians (Correct answer)
- A bus turns more sharply than a car due to its longer wheelbase
- A bus has a smaller turning radius due to its size
- The rear of a bus swings inward during turns
Correct answer: A bus has a much larger turning radius and the rear overhang swings outward during turns, creating a hazard for pedestrians
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?
- Brake fade is the reduction in braking effectiveness due to overheating, which can cause total brake failure on long descents (Correct answer)
- Brake fade is the delay in brake response in cold weather
- Brake fade occurs when ABS activates on slippery roads
- Brake fade is the gradual wear of brake pads over time
Correct answer: Brake fade is the reduction in braking effectiveness due to overheating, which can cause total brake failure on long descents
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?
- It automatically applies the brakes and stops the bus if the driver becomes incapacitated (Correct answer)
- It locks all doors if the driver leaves the cab
- It reduces engine power when the driver is fatigued
- It activates the horn if the driver's hands leave the wheel
Correct answer: It automatically applies the brakes and stops the bus if the driver becomes incapacitated
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?
- Only when the vehicle is type-approved for standing passengers and only on routes where this is permitted (Correct answer)
- Whenever all seats are occupied regardless of vehicle type
- Never — all passengers must be seated at all times
- Only on short journeys under 10 km
Correct answer: Only when the vehicle is type-approved for standing passengers and only on routes where this is permitted
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.
Question 6: What is the significance of the yellow diamond sign with a black bus symbol that may be posted at a bus stop?
- It indicates a bus priority stop where other vehicles must not obstruct or park (Correct answer)
- It marks a terminus where buses turn around
- It indicates a school bus zone with reduced speed
- It designates an accessible bus stop for disabled passengers
Correct answer: It indicates a bus priority stop where other vehicles must not obstruct or park
The yellow diamond with a bus symbol marks a designated bus stop zone (Haltestelle) where parking and stopping by other vehicles is strictly prohibited.
