6. Pregunta 6 de 25

   What should you do before going down a long, steep hill in a lorry?

   • AStay in a high gear and use only the footbrake all the way
   • BChoose a lower gear before the descent, and use the endurance brake
   • CSelect neutral at the top and coast down to save fuel
   • DSpeed up near the top so the descent takes less time
   Ver respuesta

   Respuesta: B. Choose a lower gear before the descent, and use the endurance brake

   A lower gear and an endurance brake (retarder) help control speed so the service brakes do not overheat and fade.

7. Pregunta 7 de 25

   What can happen if you use the footbrake continuously on a long downhill stretch?

   • AThe fuel will start to freeze
   • BThe tyres will over-inflate
   • CThe brakes can overheat and fade
   • DThe engine will stall
   Ver respuesta

   Respuesta: C. The brakes can overheat and fade

   Continuous braking makes brakes overheat and lose effectiveness. Use a lower gear and the retarder.

8. Pregunta 8 de 25

   Why should you avoid coasting downhill in neutral?

   • AIt is only allowed on motorways
   • BYou lose engine braking and have less control
   • CIt wears out the tyres more quickly
   • DIt stops the tachograph recording
   Ver respuesta

   Respuesta: B. You lose engine braking and have less control

   Coasting removes engine braking, so the brakes have to do all the work and you have less control.

9. Pregunta 9 de 25

   What does an anti-lock braking system (ABS) help you do in an emergency stop?

   • AKeep steering control while braking hard
   • BDrive faster in the wet
   • CBrake without pressing the pedal
   • DStop in half the distance on any surface

   ABS stops the wheels locking, so you can still steer. It does not always shorten stopping distances.

10. Pregunta 10 de 25

    • DTo remove water that collects and can freeze or damage the system
