Before I drive my wee lorry, at the start of every shift, I have to go through a set routine checking for faults.
Checks include lights, indicators, horn, wipers and washers, brake function, tyres, wheel nut indicators, mirrors, loose stuff and on and on.
This has to be noted, faults reported, action noted and all recorded on my tacho card so that when VOSA as was pull me over for a roadside check I can demonstrate (in theory) that I took the time to go through the procedure.
None of the above threw up the impending catastrophic failure of a propshaft bearing and a couple of other biggies but it helps keep things straight and saves drama with fines and penalty points.
You can only do your best.
