How does an adaptive cruise control (ACC) basically work in a bus?

If the system detects a slower vehicle in my lane, the service brake of my bus is electronically activated if necessary

If the system detects a slower vehicle in the lanes to the right or left of my bus, the service brake is electronically activated if necessary

If the system detects a slower vehicle in my lane, the retarder of my bus is electronically activated

Sensors or cameras at the front of the cab detect vehicles driving ahead of my bus in my lane

What is the basic purpose of a traction control system (ASR) in a bus?

It prevents tipping over when a curve is driven too fast

It prevents individual driven wheels from spinning when starting, especially on slippery roads

It prevents individual driven wheels from spinning when braking

It prevents individual driven wheels from spinning when accelerating, especially on slippery roads

You want to replace a battery in your bus. What do you observe?

Due to the high weight of the battery, I should not lift it alone

Due to escaping acid, I should wear eye protection

Due to the high weight of the battery, I should wear suitable safety shoes

Due to escaping fumes, I should wear respiratory protection

You are driving a bus of vehicle class M2. At what speed does the speed limiter regulate at the latest?

At 90 km/h

At 110 km/h

At 100 km/h

At 80 km/h

How should you behave if you notice that a fuse has blown in your vehicle?

If the new fuse blows again after replacement, I visit a specialist workshop

I replace it with a stronger fuse

I replace it with a new fuse as specified in the operating manual

I replace it with a weaker fuse

How does the speed limiter work in a bus?

It causes a warning to flash on the dashboard at 100 km/h. Then I should release the accelerator

It reduces engine power when the set maximum speed is reached

It automatically applies the retarder system when the set maximum speed is reached

It automatically applies the service brake when the set maximum speed is reached

Your bus is equipped with a speed limiter. Why must the limiter always be functional?

Because otherwise the digital tachograph does not function properly

Because otherwise the vehicle will be immobilized during a traffic control

Because otherwise high penalties are threatened

Because otherwise there is always a shared fault in a traffic accident

What purpose do electrical fuses serve in a vehicle?

They protect the electrical system from overloading

They are meant to prevent cable fires

They reduce the voltage from 24 volts to 12 volts

They reduce power consumption

What is the purpose of a speed limiter?

It prevents all buses from exceeding a speed of 100 km/h by engine power

It prevents all vehicles for passenger transport from exceeding a speed of 100 km/h by engine power

It prevents all buses from exceeding a speed of 95 km/h

It prevents all vehicles with more than 3.5 t maximum permissible gross weight from exceeding a speed of 100 km/h by engine power

What must you observe when reversing with your bus?

If my bus has no reversing warning device, I must use the reversing camera provided instead

If the reversing warning device is switched off, the hazard warning lights must be switched on automatically when reversing

From 10:00 PM to 5:00 AM the next day, I should switch the reversing warning device to a quieter setting

If my bus has a ramp mirror for observing the right side of the vehicle, no reversing warning device needs to be used

What should you regularly check on your bus batteries?

Whether the batteries are adequately secured

Whether the cables are adequately secured to the terminals

That the batteries are adequately coated with powder

The cleanliness of the battery terminals

Why should you only use navigation systems in a bus that use special software for bus navigation?

Because only these systems consider that not all roads are passable for heavy buses

Because only these systems consider that not all roads are passable for larger buses

Because only these systems work with the vehicle voltage

Because only these systems can be set so that specifications for navigation regarding the limits for permissible height, width, length and weight of buses can be entered

13 / 15

Category: Class D -2- Vehicle Technology - Level 1

Which navigation systems are sensible for buses?

Retrofitted systems that use special software for bus navigation

Factory-installed systems that use special software for bus navigation

Any mobile phone or tablet that has navigation software

Any navigation system for cars

What is the basic purpose of an adaptive cruise control (ACC) in a bus?

If the bus threatens to tip over in a curve, the system triggers a steering intervention that stabilizes the bus

If a slower vehicle is driving in my lane, a consistent safety distance to this vehicle is automatically maintained

If the lane is unintentionally left to the side, the system triggers a steering intervention that stabilizes the bus

If the distance to a vehicle ahead is large enough, my bus is accelerated to a preselected speed

Your bus is equipped with a reversing camera. What must you observe when using this camera?

The reversing camera definitely does not replace a person directing you

There may be a highly distorted display of the area behind the bus

Objects may appear much further away than they actually are

There is a danger of reversing too fast due to the distorted display of the area behind the bus
