Some learner drivers have problems maintaining the correct speed when negotiating hills.
It is important to be in the correct gear for the incline you are negotiating. When going uphill you need to be in a gear that is powerful enough to allow you to drive at an appropriate speed up the hill. When going downhill you need to be in a gear that is low enough to assist you in controlling the speed of your car whilst travelling down the hill. This is known as engine braking.
As a general rule, use the same gear for going down a hill, as you would for going up the same hill. This means: STEEPER THE HILL = LOWER THE GEAR.
Stay safe and enjoy your driving.
