How should you manage speed on an incline?

Managing speed on an incline is crucial for maintaining control and safety while driving a commercial vehicle. It is essential to reduce speed before ascending a hill, as doing so helps prevent engine strain and allows for better control of the vehicle's power and momentum. By slowing down before climbing, you ensure that the engine can deliver sufficient power to overcome the incline without overloading it.

Allowing extra power while climbing is also key, as it helps maintain a steady ascent without stalling or losing momentum. This approach not only reduces wear on the engine but also enhances safety by keeping the vehicle stable and avoiding sudden speed changes that could affect control.

Maintaining the same speed throughout an incline can lead to inadequate power to climb, which may result in stalling or losing control. Similarly, speeding up before ascending could increase the risk of losing traction or control, especially if the incline is steep. Lastly, continuously accelerating is not advisable as it can lead to excessive speed and a lack of control on descents, which poses significant safety risks.
