How long’s a bit of string, there’s a lot to check on my job but IF i loaded the vehicle at end of previous shift and IF no one has used it between then it can be a struggle to make the actual checking of the vehicle last 5 minutes.
If someone else has used it and left it in their typical condition then it might be an hour before it’s in a suitable clean conditon to be used.
All depends on the standards you uphold as a driver, i’ve never left in 15 mins on a supermarket type job where you are getting a previously used by someone else tractor and find a strange trailer and never will.
Co-op you say? Winc contract? they used to expect you to find the tractor and trailer and leave in 15 mins flat on the supermarket work i did 25odd years ago, and yes some managed it, invariably the same clowns who gave me plenty of overtime taking their latest incident to the bodyshop whilst they filled in the forms.
