How does doubling of the lorry speed influence the length of the braking distance?

It doubles the braking distance.
It increases the braking distance by four times.
It does not change the length of the braking distance.

With overheating of the brakes the braking performance:

may increase.
may decrease.
does not change, regardless of the degree of overheating.

Too high pressure in the lorry tyres:

may shorten the braking distance of the vehicle.
may lengthen the braking distance of the vehicle.
does not change the braking distance of the vehicle.

In which of the these circumstances does the engine brake switch on automatically?

When the engine revolution speed is less than 1500 rpm.
When the speed of the vehicle is less than 30 km/h.
Upon activating the ABS.

What distance should you maintain when driving behind another vehicle?

Necessary to avoid collision in the event of sudden braking by the preceding vehicle.
