How should you negotiate a bend when driving a truck?
Show the correct answer
Correct answer
A. By smoothly adjusting the trajectory, taking the bend into account.
Explanation
In the photo you can see a narrow road with a sign warning of a dangerous bend to the right, a 60 km/h speed limit and guide boards on the bend. You take bends by smoothly adjusting your path to the curve of the bend - the answer is A.
The Road Traffic Act requires you to drive at a speed that allows you to keep control of the vehicle, taking into account the terrain, the condition of the road and the vehicle's load. In a lorry, the high centre of gravity and the large mass mean that a sudden movement of the steering wheel in a bend easily ends in a skid or even in the vehicle turning over. That is why you slow down before a bend, and in it you drive the vehicle smoothly, without jerky movements. Driving with the clutch pedal pressed (answer B) takes away your engine braking and your control over the drive, and maximum engine speed (answer C) means unnecessary acceleration where you need calm. Also remember that on a tight bend a semi-trailer cuts the corner, so you take it wider.
