Some helpful driving tips

One of the most frustrating problems the learner driver encounters is stalling the engine as the car moves off. With the car in first gear, you release the clutch pedal to the bite, release the handbrake and press the gas pedal.
Stalling arises when the clutch pedal and the handbrake are released incorrectly i.e. the clutch is released to fast, or not releasing the handbrake in time, not enough gas.
