Class E (Truck) -5- Hazard Awareness, Hazard Prevention - Level 3

3 of 3 Levels

1 / 12

Category: Class E (Truck) -5- Hazard Awareness, Hazard Prevention - Level 3

You are driving an articulated vehicle that has 40 t gross weight. What must you consider if you want to leave the highway here?

I must adjust my driving speed so that the articulated vehicle does not tip over

I may only brake in the exit curve so as not to endanger traffic on the highway

Due to the guide arrows, I must expect that the exit curve has a particularly tight radius

I must adjust my driving speed to the limited visibility in the curve

Category: Class E (Truck) -5- Hazard Awareness, Hazard Prevention - Level 3

You are driving an articulated vehicle here. How must you behave when oncoming traffic appears?

After I have stopped, I communicate with the driver of the oncoming vehicle about who gives way

I have right of way as long as no larger vehicle than my articulated vehicle is coming

I stop preferably where there is no tree next to my articulated vehicle

I steer my articulated vehicle between the trees into the grass

Your articulated vehicle has a box body with a refrigeration unit. You have parked it outside overnight. It has snowed heavily at sub-zero temperatures. What must you do before starting the journey?

I must definitely mount snow chains on the tractor unit

I must definitely switch off the refrigeration unit

I clear the lights and reflectors of snow

I clear the roof of the box body of snow and ice

You are driving an unloaded articulated vehicle. Why must you expect very low tire grip on the road surface here?

Because the tire grip on the road surface results from the multiplication of the friction coefficient between tire and road surface times wheel load

Because with an empty tractor unit, the wheel load especially on the rear wheels is very high

Because the friction coefficient between tire and road surface only reaches about 0.2 on snow-covered roads

Because with an empty articulated vehicle, the wheel load especially on the rear wheels of the tractor unit and semi-trailer is very low

You are driving an articulated vehicle here at about 70 km/h. The cyclist is riding at about 40 km/h. Why should you give a warning signal with the horn when overtaking?

So the cyclist does not suddenly move to the left

Because there is a large speed difference between both vehicles

So the cyclist does not suddenly brake

Because the cyclist cannot easily perceive vehicles approaching from behind

Your articulated vehicle has a box body. You have parked it outside overnight. It has snowed heavily at sub-zero temperatures. Why must you clear the roof of the body of snow and ice before starting the journey?

When braking, ice and snow could come loose from the roof and be thrown forward. This can endanger other people or damage vehicles

When the box body warms up, ice and snow could come loose from the roof and damage vehicles

When the box body warms up, ice and snow could come loose from the roof and endanger other people

When the box body is warmed by sunlight, meltwater penetrates the cargo space

Category: Class E (Truck) -5- Hazard Awareness, Hazard Prevention - Level 3

You are driving an articulated vehicle here at about 70 km/h. The cyclist is riding at about 40 km/h. How should you behave when overtaking?

I change to the left lane early

I give a warning signal with the horn

I give a warning signal with the headlight flasher

I look in the left mirror and signal if I am not being overtaken

8 / 12

Category: Class E (Truck) -5- Hazard Awareness, Hazard Prevention - Level 3

You are driving an articulated vehicle that has 40 t gross weight. What circumstances can cause the articulated vehicle to tip over here?

If driving too slowly through the exit curve

If the cargo shifts due to inadequate cargo securing

If the articulated vehicle including cargo has a high center of gravity

If the cargo consists of beef or pork carcasses hanging from the ceiling in a refrigerated body

9 / 12

Category: Class E (Truck) -5- Hazard Awareness, Hazard Prevention - Level 3

You are driving an articulated vehicle here. What must you pay particular attention to when choosing your driving speed?

Leaves on the road lead to an exceptionally long braking distance

Overhanging branches can damage the body of the articulated vehicle

The road is so narrow that a safe encounter with oncoming traffic is not possible

There is a high probability of wildlife crossing

10 / 12

Category: Class E (Truck) -5- Hazard Awareness, Hazard Prevention - Level 3

You are driving an articulated vehicle here that has 20 t gross weight. Does the articulated vehicle need snow chains?

Yes, on the steered front wheels of the tractor unit

Yes, on one axle of the semi-trailer

Yes, on the drive wheels of the tractor unit

11 / 12

Category: Class E (Truck) -5- Hazard Awareness, Hazard Prevention - Level 3

You are driving an articulated vehicle here that has 20 t gross weight. What dangers must you expect if you try to handle the descent without snow chains?

The articulated vehicle could start sliding

The engine of the tractor unit could be overloaded

The articulated vehicle could become unsteerable

The brakes of the semi-trailer could overheat

12 / 12

Category: Class E (Truck) -5- Hazard Awareness, Hazard Prevention - Level 3

You are driving an unloaded articulated vehicle. What must you particularly consider here when choosing your driving speed?

The low axle pressure on the drive wheels

The low friction between tires and road surface

The visibility

The narrow remaining road width
