You are driving a bus up an incline. What must you observe regarding driving force to overcome the gradient resistance?

The driving force of the bus must be greater than the driving resistances

The gradient resistance must always be greater than the driving force of the bus

The gradient angle must always be greater than the driving force of the bus

The driving force of the bus must always be less than the driving resistances

You are driving a bus. What driving resistances occur during driving?

The rolling resistance of the tires on the road

The gradient resistance of the bus when driving on inclines

The air resistance of the bus

The acceleration resistance of the bus when accelerating

What advantages does careful route planning bring?

It usually results in a shorter driving time than with spontaneous route selection

It definitely results in a longer driving time

Rush hours and traffic jam-prone roads can be avoided

Driving breaks can be planned in advance so that they can be taken at the optimal time at a suitable location

4 / 15

What factors influence the gradient resistance of a bus?

The total weight of the bus

The road condition

The gradient angle of the roadway

The driving speed of the bus

How does the driving speed affect air resistance?

At double the driving speed, the air resistance becomes half as large

At double the driving speed, the air resistance becomes four times as large

At double the driving speed, the air resistance becomes twice as large

At double the driving speed, the air resistance remains the same

You are driving a bus with a manually shifted transmission and driving up an incline. When must you downshift?

Always only when the engine begins to vibrate heavily

Always only when the engine speed has dropped to idle speed

When the engine speed threatens to drop below the green range of the engine tachometer despite full throttle

When the engine speed can only be kept in the green range of the tachometer with full throttle

8 / 15

Category: Class D -8- Eco-friendly Driving, Operating Rules, Equipment - Level 1

You are driving a bus with a manually shifted transmission. How should you behave when driving on inclines?

I should accelerate fully when the engine speed begins to drop

I should always select a gear with which I can drive the incline in the green range of the engine tachometer

I should always accelerate fully until the end of the incline

I should always select a gear with which I can drive the incline in the yellow range of the engine tachometer

9 / 15

Category: Class D -8- Eco-friendly Driving, Operating Rules, Equipment - Level 1

What is the purpose of the green range of the engine tachometer?

It shows the engine speed range with the lowest torque

It provides guidance for the correct shifting time

It shows the engine speed range with the lowest specific fuel consumption under full load

It shows the engine speed range with high torque

10 / 15

Category: Class D -8- Eco-friendly Driving, Operating Rules, Equipment - Level 1

You are driving a bus with a manually shifted transmission. Which measures have a fuel-saving effect?

When accelerating, I skip individual gears if possible

I select the gear so that the required torque is achieved at high engine speed

I select the gear so that the required torque is achieved at low engine speed

I make sure to keep the engine speed under load as much as possible in the green range of the tachometer

11 / 15

How must you mark your bus when carrying out a school transport?

By a white square sign with the child symbol on the front of the bus

By a yellow-red square sign with the child symbol on the rear of the bus

By yellow-red square signs with the child symbol on the side walls of the bus

By the inscription "School transport" on the destination sign

Where can you find information about the optimal speed range of your bus?

On a sticker on the right side of the vehicle

On the printout from the digital tachograph

In the registration certificate of the bus

In the operating manual of the bus

13 / 15

You are driving a bus with a manually shifted transmission. What options do you have to reduce fuel consumption?

I should only upshift when the needle of the engine tachometer is at the upper end of the yellow range

I only fill up with eco-diesel fuel

I turn off the engine during longer stops or use - if available - the start-stop system of the bus

I regularly check the tire pressure
