On the slip resistance of the loading surface

On the weight force of the cargo

On the driving speed

How do you calculate the friction force of the cargo in the luggage compartment of a bus?

The friction force is always equal to the weight force of the cargo

The weight force of the cargo times the coefficient of friction between cargo and loading surface

Double the weight force of the cargo times the coefficient of friction between cargo and loading surface

Half the weight force of the cargo times the coefficient of friction between cargo and loading surface

Why are objects such as beverage crates, suitcases and the like not allowed to stand in the aisle of your bus during the trip?

Because the floor in the aisle does not have sufficient strength

Because adequate cargo securing in the aisle is impossible to establish

Because the aisle serves as an escape route in case of emergency

Because the floor in the aisle has too high a coefficient of slip

When leaving the roadway

During emergency braking

During sharp evasive maneuvers

You are supposed to stow the suitcases of a tour group in your bus. What do you observe?

I stow the suitcases as gap-free as possible in the luggage compartment of the bus

If the luggage compartment is fully loaded, I ask the passengers to stow smaller suitcases in the overhead luggage racks in the passenger compartment above the seats

I ensure that the suitcases are loaded as form-fitting as possible to the front wall, partition struts and side walls of the luggage compartment

If the luggage compartment is fully loaded, I ask the passengers to place the suitcases in the aisle of the passenger compartment

10 / 15

Category: Class D -4- Driving Operations - Level 2

Which circumstances promote tipping of a bus?

If the steering wheel is jerked while braking hard

If the bus has a high center of gravity like double-decker buses

A low overall center of gravity of bus, passengers and luggage

A high overall center of gravity of bus, passengers and luggage

Forces act on the cargo during driving. In which direction can the greatest force occur?

The forces are equal in all directions

Rearward

Sideways

Forward

You are supposed to stow the suitcases of a tour group in your bus. The number of suitcases does not allow loading the entire luggage compartment full. What do you observe in this case?

In the compartments of the luggage area that cannot be loaded gap-free, I secure the suitcases with lashing straps. I attach the lashing straps to the struts in the luggage compartment

I stow the suitcases so that individual compartments in the luggage area of the bus are loaded gap-free

I stow the suitcases so that they are loaded as form-fitting as possible in individual compartments to the front wall, partition struts and side walls of the luggage compartment

In the compartments of the luggage area that cannot be loaded gap-free, I secure the suitcases with lashing nets. I attach the lashing nets to the lashing points in the luggage compartment

You notice before departure that passengers have placed beverage crates in the aisle of your bus to consume drinks during the trip. How should you behave?

I ensure that the beverage crates in the aisle are secured with anti-slip mats

I ensure that the beverage crates in the aisle are secured with lashing straps

I ensure that the beverage crates are loaded securely in the luggage compartment of the bus. For transporting the beverage containers, I offer the use of coolers in the passenger compartment

I designate a passenger to hold each crate during the trip

14 / 15

Why must cargo in a bus be secured?

So that the cargo definitely remains in or on the vehicle in case of an accident

So that the roadway is not damaged

So that driver, co-driver, passengers and other road users are not endangered

So that cargo and vehicle are not damaged

15 / 15

You are driving a double-decker bus occupied with 70 passengers. Why is the tipping risk particularly high?

Because due to the large number of luggage pieces carried in the cargo area, a high load center of gravity results

Because due to the large number of passengers, many seats in the upper deck of the bus are occupied. This results in a high load center of gravity

Because due to the large number of luggage pieces carried in the cargo area, a low load center of gravity results

Because double-decker buses have a high body center of gravity
