Your car’s engine has a lot of work to do when moving off from a stationary position. It has to get your car and passengers (totaling around 1.5 ton) from a stationary position, into motion. For this to happen, you’ll need to provide power to the engine.
If you’re driving a manual car and assuming the car is ready to go; 1st gear selected with the clutch down and parking brake on, gently apply a little gas. To give you an idea of how much, press the accelerator pedal a small amount – about the thickness of a one pound coin, or until the needle on the rev counter reaches around 1500 RPM. You can then release the parking brake and gently release the clutch.
If you’re driving an automatic, press the foot brake down with your right foot, select ‘drive’ on the gear selector, release the parking brake and from the brake pedal, apply pressure to the accelerator slightly and gradually using your right foot.
