In short
Parking forward or reverse into a marked bay; one of the four UK test reversing manoeuvres.
Bay parking is one of the four reversing manoeuvres on the UK practical test. The examiner will ask you to either drive into a bay forward and reverse out, or reverse into a bay.
Reference points and observation matter more than precision — the examiner expects you to look over your shoulder, not just rely on mirrors.
