If it’s a decent operator they’ll be looking for good vehicle control, they’ll probably give you a bit of test re road signs drivers hours etc, but doubt it will be as pedantic as the typical logistics mobs utter ■■■■■■■■ box ticking marathon, the difference being with tanker operators driving competence will be a higher priority than checking the small print.
Daf auto is same gearbox as Iveco, but usually better programming, if its a CF they are the only lorry i tend to kerb the NS trailer wheels with until used to it, dunno why maybe its where the driver’s seat is, and the switchgear on CF’s is simply bizarre, other than that its just another modern lorry where all you have to do is steer.
