The swap happened at Stafford services northbound at two in the morning. Different unit coming the other way, swap the trailer, hand over the paperwork, done in fifteen minutes. I didn't do a proper walk-round. It was dark, I was tired, the other driver said the unit was fine. I took it on faith.
Found the nearside rear scuff at the delivery yard in Carlisle at first light. About 600mm of bodywork damage at axle height — looked like a dock strike. Could have been the previous driver. Could have been a loading bay. Could have been me reversing at Stafford in the dark, although I don't think it was. The problem was I had no proof either way, and the delivery yard photographed it the moment I dropped the curtain.
Couldn't prove it wasn't me. Should have been able to.
What drop-and-hook actually means on the tachograph
Drop-and-hook is when you leave one trailer and collect another — at a services swap point, a yard, a loading bay, or a roadside handover. From a tachograph and drivers' hours perspective, swapping trailers doesn't reset any of your clocks. Your daily driving accumulation continues. Your rest period, if you're mid-rest, continues. Your weekly driving total continues. The trailer is irrelevant to the tachograph record — it's the driver card and the vehicle unit that matter.
One thing that does matter: if you swap into a different tractor unit as part of the same move, the new vehicle unit should be recording your activity with your card inserted. Make sure your card goes in the new unit immediately. If you're doing a cab swap as well as a trailer swap, the moment you take the wheel of the new vehicle, your card needs to be in it. Any gap — driving without a card inserted, or driving with the previous driver's card still in the reader — creates an infringement record on both sides.
If the drop-and-hook involves any delay between leaving the first combination and taking the second — waiting for the other driver, sorting paperwork, a refuelling stop — record your activity mode accurately. If you're waiting in the cab and freely disposing of your time, that's rest or availability time. If you're sorting the handover paperwork or checking over the replacement unit, that's other work. Put it on the tacho correctly. An unexplained gap on the card is a conversation you don't want at a roadside check.
The walk-round you can't skip — especially on a collected unit
The statutory obligation for a pre-drive defect check comes from the Road Traffic Act 1988 and the Goods Vehicles (Plating and Testing) Regulations, backed up by the operator licence conditions. Broadly: drivers must not drive a vehicle in a dangerous or defective condition, and the operator has an obligation to ensure vehicles are roadworthy before departure.
In practice, that means a walk-round inspection before every journey. Most drivers do this at the home depot where they know the unit. Plenty of drivers skip it or abbreviate it on a trailer collection at two in the morning in an unfamiliar services car park.
That's exactly where it matters most. When you collect a unit from a handover point, you're accepting responsibility for it from that moment. Any defect that exists when you take it — a flat tyre, a broken light, kerb damage, a missing light board bracket — is your problem the moment you pull out of the services. If DVSA stops you on the A74(M) an hour later and finds a cracked tail-light lens that was cracked when you collected the unit, you still get the PG9. 'The other driver said it was fine' is not a document.
What the walk-round needs to cover on a collected trailer
Same as any other walk-round, but pay particular attention to the things that get damaged in yard work and loading bays: rear doors, nearside bodywork (dock strikes), rear light clusters, number plate illumination, curtain track and buckle condition if it's a curtainsider. Run through the combination lights — trailer marker lights, tail lights, reverse lights, brake lights. Get someone to step on the brakes while you check the rear if you're alone.
Check the landing gear. On a collected trailer, you don't know whether it was wound up correctly by the previous driver. A leg that's not properly stowed can clip the ground on a ramp exit and tear off entirely, or catch on the fifth wheel and cause a coupling failure. Takes ten seconds to check both legs are up and locked.
Coupling check: when you've hitched up, get out and check the coupling is secure. Pull forward slightly against the trailer brakes to confirm the fifth wheel has engaged properly. Visually check the coupling lock is in. This sounds like the basics — it is the basics — but handover points at night are where 'just trust the connection' thinking happens.
The defect report and the evidence gap
Before you move off, the defect report needs to cover the state of the vehicle as you found it. If you find damage, note it on the report, photograph it, and if the other driver is still present, get them to countersign or acknowledge it in writing. If you're at a services where the handover is done and the other driver has gone, a timestamped photograph with your own phone gives you evidence of what the trailer looked like when you collected it.
That photograph from the Carlisle delivery yard would have been a problem for me if the scuff hadn't existed at Stafford. It was a problem for me because I couldn't prove I'd inspected the trailer and found it undamaged. The walk-round isn't just about finding defects. It's about documenting the condition at the point you accepted responsibility.
In a well-run fleet, the defect report from the outgoing driver at the handover point should travel with the paperwork. The incoming driver's walk-round checks it against reality. Any new damage is noted, photographed, and reported back to the TM before departure. That chain of documentation is what makes liability clear when the delivery yard rings up with a claim.
Damaged trailer and the insurance question
When a damage claim arrives, the operator's insurer wants to know: when did it happen, who was driving, and was there a walk-round report? If the answer to the third question is 'not really' or 'the driver did one but didn't write anything down,' the claim sits ambiguously and the insurer may look at the driver's employer as the responsible party regardless of the actual cause.
Operators who run drop-and-hook operations regularly have processes for this: a standard handover checklist, a photo protocol, a specific defect report number for collected trailers that differs from the home-fleet defect report. It's paperwork, but it's the paperwork that matters when the phone rings.
For tramping drivers doing ad hoc handovers, the phone camera is your friend. Thirty seconds of photos — all four corners, rear doors, tyres, coupling — before you move. Timestamp, geolocation, send to your TM. That's evidence. It costs nothing and it's one of those habits that feels unnecessary right up until it saves you £4,000.
The tachograph side of an overnight trailer park
One more thing worth knowing: if you're tramping and you park a trailer overnight at a services or a drop point and collect it again in the morning, the unit has been stationary. Depending on your tachograph setup and the vehicle unit, the VU continues logging while the vehicle is stationary — it records ignition off, rest mode on the driver card. That's all normal.
Where it gets complicated: if someone else has moved the trailer or vehicle while you were resting — a yard shunter, a second driver — their activity should be on their own driver card. If the vehicle's VU shows driving activity during your rest period without a corresponding driver card record, that's a flag in the analysis report. Doesn't happen often, but on cross-carrier handover operations it's worth knowing that unexplained VU activity can look strange until you explain the context.
