Trailer plate

Luckily I’ve only been doing class 2 work up to now ( for the last 2 years ) so nothing like that has ever happened to me but when whenever i start thinking about doing class 1 i can get myself worried about all the checks that need doing, plate, sueies, 5th wheel, dog clip, legs ect.

Apparently there is an easy way to remember it which ironically I’ve forgotten he he he, it goes something like:-

B
L
A
N
K

Brakes.
Legs.
Air lines.
Number plate.
And something else.
