With Daily vehicle custody on (Settings → Features), the end-of-day yard wizard asks each crew for their van's closing mileage and whether they're taking one home; the morning briefing takes the opening reading back before the day's vehicle pick.
You get an unbroken record of who had which van and every overnight bracket — and if a van moves significantly overnight without explanation, the office is asked about it rather than nobody noticing. Left off, the lighter weekend-only checks apply.
Off-the-clock miles are personal, automatically. For a van that goes home with someone, every mile between their clock-off reading and the next morning's clock-on reading is the commute, and the commute is private use. Each of those overnight gaps goes straight into the personal mileage log the moment the morning reading lands, no confirming needed. The morning reading is compulsory for a van that goes home: the day clock-in asks for it and won't open the shift without it, because one missing reading loses the whole night. The keeper sees the last week's nights on their Today screen and can flip one to business if it was genuinely a late job or a run to the merchant. Where a reading was missed on a night the keeper worked both sides of, the night goes down at the van's usual commute, marked estimated, and swaps to the measured figure if the readings turn up. The Mileage report then shows business miles with the commute already taken out, which is the split the accountant wants, and it can be viewed by pay period (same cut-off as Timesheets) so the personal figure matches the dates payroll runs to and from.
Pre-use checks. Turn on Pre-use vehicle checks (Settings → Features) and a van or trailer that hasn't been checked today shows Check & take in the morning list instead of Take. It's a two-minute walkaround — lights, tyres, brakes, coupling and breakaway on a trailer, load secure. Pass it and the vehicle is yours for the day; mark a safety item Not OK and it stays in the yard, an urgent fault goes to the office and the crew are told to pick another. End-of-day and weekly checks carry on as before.
Crews with their own vehicles. By default vehicles are a shared pool — crews take what they need that morning. Turn on Crews have their own vehicles and each crew gets a Usual vehicle (Team → Crews) that's tagged and shown first on their morning list, and vans and trailers can be put on rounds like any other kit. Custody, mileage and towing work the same either way.
Where a machine is. A machine's status is now just In service or Off the road. Whether it's at the yard or out with a crew is worked out from the morning check-out, so you'll never see "at yard" and "out" at the same time.
