Assuming you're driving a car with a manual gearbox, a reverse hill start is fairly straight-forward.
To Start with, you need to have your handbrake fully on, this will stop the car from rolling.
With your clutch pedal pushed fully down, select reverse, then gradually bring your clutch pedal up towards the biting point. Once you find this, your car will try to move. At this point take your hand brake off, and you'll start moving up the hill.
Simples
reverse and set the parking brake.
keep hand brake
turn your wheels toward curb
If leaving a vehicle parked on a hill, I would engage the parking brake and shift the transmission into the appropriate gear: in a manual, I would leave it in first gear when facing uphill and reverse when facing downhill; in an automatic, I would put it in "Park." If there's a curb, I would turn the front wheels away from the curb when parked uphill and toward the curb when parked downhill to provide additional security against rolling. This combination helps ensure the vehicle remains stationary and safe.
The handbrake is used to stop a stationary car rolling downhill. The transmission can also stop a car from moving when parked.
The person who is backing out
Backwards, then forwards from the rebound.
If you reverse your car and then collide with a parked car , the person who did the reversing is at fault.
yes
If the handbrake isn't on and something is pushing it backwards (gravity, another car, etc.) then yes. Cars don't roll on their own.
In a downhill area, you should always park with the front wheels toward the curb. The theory is that if the brakes malfunction, the car will move towards the curb and stop, instead of going downhill, gathering speed and causing an accident.
