Pull up alongside your target car, I metre away and steering wheels level. When it is clear all around, turn-in one turn, stop when kerb disappears in right hand corner of rear window (when looking in mirror) (or point on bumper): Then turn full-lock right. Remember to keep looking over your left shoulder. If necessary you can shunt forwards at least twice to correct it, or re-align it, if you are unsure. If you do shunt forwards make sure that it is enough to be useful.
You should be looking over your shoulder – out of the rear window at least half of the time when reversing
On the Test
You must complete the manoeuvre within two of your own car lengths. If you go beyond this you will fail. You should also finish within about 30cm from the kerb. If it goes wrong shunt it forwards to correct it - do not leave it in an untidy position. As always all-round observation is of utmost importance, especially behind.
