You need to position your car past the junction (remember to look up the road you are reversing into make sure it's safe) your position should be a steering wheels distance from kerb and car should be parallel to the kerb steering wheel straight.
You need to observe all the way (7 point check as you are reversing) around before you move starting at right shoulder all the way to the back window, you are looking for vehicles and pedestrians you can only move your vehicle when it's safe to do so, if there are vehicles far away you could make some progress in a straight line to your turning point.
When it's safe you are going to move slowly backwards keeping that same distance from kerb you are going to stop at your turning point this is when your back wheel is at the end of your last straight kerb stone, look in your left blind spot mirror for this reference point. (see fig 1).
Pause the car at this point. Remember to keep checking all around for approaching vehicles you should stop if this happens and establish where they are going. Keep still if cars are coming past you.
Looking in your back side window on left assess what corner you have sharp, intermediate or sweeping (see fig 2,3,4). Do another 7 point check If the road is clear of vehicles and pedestrians move the car very slowly turn the steering wheel wheel left the correct amount for the type of
corner you have. If you get too close to the kerb turn the wheel to the right if you begin to wander away from kerb turn the wheel to the left. You may need to keep adjusting the steering as you are turning the corner try not to oversteer if you are a little close turn a little away.
Remember you are NOT allowed to go more than a metre from the kerb. If you think you may do this stop and go forwards bringing back of car towards the kerb turning left on steering.
You must constantly keep looking around observational technique is very important. If a car approaches stop until it passes, if they cannot pass then continue the manoeuvre. Sometimes if a vehicle approaches the road you are turning into you may need to go forwards and start your manoeuvre again.
When you are coming into your new road look out the back window for your reference point to straighten wheel (see fig 5) the kerb should be around the centre of the back window when you are there straighten up and reverse back 2-3 car lengths if possible.
Reverse left around a corner
Control of vehicle - remember to keep very slow your speed should be crawling on your hands and knees, lots of clutch control.
Try to be accurate - don't worry if it goes a little wrong you are allowed to fix it by going forwards and backwards. You must not touch the kerb or go too far from it. Maximum distance from kerb allowed is 1 metre ideally you should try and stay a steering wheels distance from kerb.
Lots of observations - remember to keep looking for vehicles that may want to pass by gain eye contact with approaching vehicles but do not wave them through. If a vehicle stops to allow you to continue do so if safe.
You will be stopped before junction take a good look try and decide what type of corner you have.
There are 3 types:
Sharp:a full lock turn left
(see fig 1).
Intermediate: 1 or 3/4 turn left adjust
(see fig 2).
Sweeping: 1/2 turn left adjust.
(see fig 3)
Also assess uphill downhill or flat.
