You want to tow an overrun-braked trailer with this towing vehicle. What is the maximum gross weight the trailer may have?

The gross weight of the towing vehicle and the trailer must be equal

The gross weight of the trailer must not be greater than the curb weight of the towing vehicle

The gross weight of the trailer must not exceed 1.5 times the maximum permissible gross weight of the towing vehicle

The gross weight of the trailer may be at most 3,300 kg

You are towing an overrun-braked trailer with your car. Why can the trailer brakes overheat if you drive too fast downhill?

Drum brakes of car trailers are cooled much less effectively than disc brakes of cars

The material of the car brake discs has poorer quality than that of the trailer brake drums

The material of the trailer brake drums has poorer quality than that of the car brake discs

Downhill, the trailer brake is constantly applied by the trailer running up on the car

If it is entered in the registration certificate

If the towing vehicle has an off-road gear

If the towing vehicle has all-wheel drive

You are towing an overrun-braked trailer with an "off-road" towing vehicle. What weight ratio must be observed between the two vehicles?

The gross weight of the trailer plus 75 kg must not exceed the gross weight of the towing vehicle

The gross weight of the trailer must not be greater than the curb weight of the towing vehicle

The gross weight of the towing vehicle and the trailer must be equal

The gross weight of the trailer must not exceed 1.5 times the maximum permissible gross weight of the towing vehicle

6 / 11

Category: Class BE -2- Vehicle Technology - Level 2

What problems can occur when you tow an overrun-braked trailer?

Since no "stretched" braking is possible, the vehicle combination can jack-knife during hard braking

The overrun brake is ineffective when the vehicle combination is standing downhill

The overrun brake is ineffective when the vehicle combination is standing uphill

On longer downhill drives, the trailer brakes can overheat

7 / 11

When does the overrun brake of a trailer become effective?

When the trailer moves away from the towing vehicle when starting

When the trailer runs up on the decelerating towing vehicle

When the electrical actuation is triggered

By a hand lever on the towing vehicle

You want to couple a trailer with a sway damper. What do you have to pay attention to?

The ball of the towing device on the towing vehicle must be completely covered with grease

The cap of the towing device of the trailer must be heavily oiled

The cap of the towing device of the trailer must not extend over the ball on the towing vehicle

The ball of the towing device on the towing vehicle must be completely grease-free

9 / 11

You are towing an overrun-braked trailer with a non-off-road car. What weight ratio must be observed between the two vehicles?

The gross weight of the trailer must not be greater than the maximum permissible gross weight of the towing vehicle

The gross weight of the trailer must not be greater than the curb weight of the towing vehicle

The gross weight of the trailer plus 75 kg must not be greater than the gross weight of the towing vehicle

The gross weight of the towing vehicle and the trailer must be equal

10 / 11

Category: Class BE -2- Vehicle Technology - Level 2

You are towing an overrun-braked trailer with your car that has 1,400 kg gross weight. What must you pay attention to?

Because of the steep and long-lasting gradient, I must drive so slowly that the towing vehicle brakes do not overheat

Because of the steep and long-lasting gradient, I must drive so slowly that the trailer brakes do not overheat

Because of the high weight of the trailer, I must drive at least 80 km/h. Only this way are the trailer brakes sufficiently cooled by the airstream

Because of the steep and long-lasting gradient, I must primarily use the braking effect of the car engine
