The semi-trailer can start to oscillate

2 / 15

Category: Class E (Truck) -5- Hazard Awareness, Hazard Prevention - Level 1

On the left side next to the semi-trailer

Directly in front of the windshield

Behind the semi-trailer

You are driving an articulated vehicle with 40 t gross weight at about 60 km/h. How should you behave?

I must immediately stop on the emergency lane and mount snow chains on the drive wheels of the tractor unit

I change to the left lane and overtake the truck in front of me

I pay attention to traffic radio announcements about road conditions on this section of highway

I pay attention to a sufficient safety distance to the truck driving in front of me

You are driving an articulated vehicle with 40 t gross weight at about 60 km/h. Why should you pay attention to traffic radio announcements about road conditions on this section of highway?

So I can take an alternative route in time if the snow situation worsens

So I can take an alternative route in time if the highway is blocked by stuck vehicles due to the snow situation

So I do not obstruct road maintenance vehicles

So I can mount snow chains in time if the snow situation worsens

Category: Class E (Truck) -5- Hazard Awareness, Hazard Prevention - Level 1

You are driving this articulated vehicle loaded with an empty container. In which situations can this become critical from a driving technique perspective?

On uneven road surfaces or with ruts in the road surface

When braking on slippery road surfaces

When starting on slippery road surfaces

In crosswinds

6 / 15

Category: Class E (Truck) -5- Hazard Awareness, Hazard Prevention - Level 1

You are driving an articulated vehicle. During which driving maneuvers must you particularly consider the dangers arising from "blind spots" in the fields of vision?

When turning left

When overtaking

When turning right

When reversing

7 / 15

Category: Class E (Truck) -5- Hazard Awareness, Hazard Prevention - Level 1

You are driving your articulated vehicle on this highway at 60 km/h. How should you behave in this situation?

I increase the safety distance to the truck driving in front of me

I immediately steer right onto the emergency lane

If necessary, I switch on the hazard warning lights

I brake

8 / 15

Category: Class E (Truck) -5- Hazard Awareness, Hazard Prevention - Level 1

You are driving this articulated vehicle loaded with an empty container. Why can this become critical from a driving technique perspective?

The load center of gravity is far from the kingpin. This can cause the tractor unit to start oscillating

Because the tires of the semi-trailer can become heavily loaded. This means the risk of brake overloading is high

Because the tires of the front axle of the tractor unit can become heavily loaded. This means the risk of overloading is high

Because the tires of the drive wheels of the tractor unit can become unloaded. This means the tire grip is very low, especially on slippery road surfaces

9 / 15

Category: Class E (Truck) -5- Hazard Awareness, Hazard Prevention - Level 1

You are driving this articulated vehicle loaded with a fully loaded container. Why is this critical from a driving technique perspective?

The load center of gravity is far from the kingpin. This means the tendency of the semi-trailer to oscillate is high

The load center of gravity is dangerously close to the tipping edge of the semi-trailer. This means the tendency of the semi-trailer to tip is high

Because the tires of the semi-trailer become unloaded. This means the tire grip is very low, especially on slippery road surfaces

Because the tires of the semi-trailer become heavily loaded. This means the risk of tire overloading is high

10 / 15

Category: Class E (Truck) -5- Hazard Awareness, Hazard Prevention - Level 1

What dangers exist when an articulated vehicle is loaded so that the cargo is mainly above the fifth wheel coupling?

The semi-trailer can easily tip over

The semi-trailer tends to oscillate

The tires of the drive wheels of the tractor unit have very little grip on the road surface

The tires of the semi-trailer can only transmit low friction forces

11 / 15

Category: Class E (Truck) -5- Hazard Awareness, Hazard Prevention - Level 1

How does the tipping edge run on a semi-trailer?

From the kingpin to the wheel contact point of the first axle of the semi-trailer

From the wheel contact point of the first axle of the semi-trailer to the wheel contact point of the first axle of the tractor unit

From the wheel contact point of the first axle of the tractor unit to the wheel contact point of the first axle of the semi-trailer

From the center of the cab of the tractor unit to the wheel contact point of the first axle of the semi-trailer

12 / 15

Category: Class E (Truck) -5- Hazard Awareness, Hazard Prevention - Level 1

You want to drive this articulated vehicle loaded with a fully loaded container. What do you pay attention to?

I must make sure that at least 25% of the total weight of the vehicle combination rests on the drive axle of the tractor unit

I may drive in any case as long as the road is dry

I may not drive if less than 25% of the total weight of the vehicle combination rests on the drive axle of the tractor unit

I may drive in any case if I am transporting the container in the pre-carriage or on-carriage of combined transport

13 / 15

Category: Class E (Truck) -5- Hazard Awareness, Hazard Prevention - Level 1

You are driving this articulated vehicle loaded with a fully loaded container. How should you behave?

I avoid - if possible - strong acceleration

I drive particularly carefully in curves

I avoid - if possible - braking in curves

I expect that on slippery roads the tires of the drive wheels will start spinning very early

14 / 15

Category: Class E (Truck) -5- Hazard Awareness, Hazard Prevention - Level 1

You are driving your articulated vehicle on this highway at 60 km/h. Why should you brake in this situation, increase the safety distance to the truck in front of you, and switch on the hazard warning lights?

Because I can then form a rescue lane more safely

Because otherwise there is a danger of a rear-end collision

Because I cannot see the situation in front of me due to the truck

Since the vehicles in the column next to me and the truck in front of me are braking, I must expect a traffic jam

15 / 15

Category: Class E (Truck) -5- Hazard Awareness, Hazard Prevention - Level 1

You are driving an articulated vehicle with 38 t gross weight. The tractor unit has an automated transmission. How should you behave after these traffic signs?

I select a higher gear

I accelerate

I use the retarder on the descent
