When is a single-axle trailer correctly loaded for stable driving behavior?

When the trailer does not load the trailer coupling as much as possible

When the trailer slightly relieves the rear axle of the towing vehicle

When the trailer is loaded so that it only rests on the trailer coupling with the permissible drawbar load during emergency braking

When the trailer rests on the trailer coupling with the permissible drawbar load

You are pulling a trailer of vehicle class O2 with your car. Must you signal in this situation?

No, since I am already positioned in the correct lane for turning

Yes, I must announce every intended change of direction in time by signaling

Yes, I must indicate every steering movement with the turn signal

No, since I am not allowed to drive differently anyway

You are pulling a horse trailer with your SUV. Oncoming traffic is approaching. How will you behave in this situation?

I will initiate full braking so that the oncoming traffic can pull into the parking space

I will switch on the right turn signal and pull into the parking space with a gentle steering movement

I give the oncoming traffic a hand signal to pull onto the sidewalk

I will switch on the left turn signal and pull into the parking space with a gentle steering movement

You are pulling a caravan with your SUV. Why must you switch on the left turn signal early?

Because following drivers cannot see the bottleneck due to my trailer

Because the cyclists have a duty to yield if I signal in time

To indicate to following drivers that they should not overtake while I am braking

Because following drivers expect from the turn signal that I will slow down

10 / 15

Category: Class E (Truck) -9- Hazard Awareness, Hazard Prevention - Level 1

You are pulling a horse trailer with your SUV. Why must you switch on the left turn signal when pulling over?

Because the left turn signal is better seen by following drivers than the right turn signal

If I signal left, following drivers expect that I have to pass an obstacle

If I signal right, following drivers might assume that I want to enter the parking space

A switched-on right turn signal tempts following drivers to overtake my vehicle

11 / 15

Category: Class E (Truck) -9- Hazard Awareness, Hazard Prevention - Level 1

For which trailers or loads on trailers is there an increased tipping danger?

For a horse trailer loaded on the right side in a left curve

For a transport trailer for gliders

For a low-loader trailer loaded with flat steel

For a boat trailer loaded with a tall sailboat

How can you determine the actual drawbar load of your trailer?

There are special scales available in accessory stores for this

By pressing down the drawbar with my foot

I support the drawbar at the height of the trailer coupling on a personal scale

By lifting the drawbar with the jockey wheel

You want to couple a single-axle trailer to a car. How can you determine the actual drawbar load?

I support the drawbar at the height of the trailer coupling on a personal scale

I observe how far the axle of the trailer compresses after coupling

There are special scales available in accessory stores for this

I observe how far the rear axle of the towing vehicle compresses after coupling
