- Humberside Police have confirmed hiding speed cameras and officers with speed guns in a tractor, a horsebox — and roadside hedges.
- Since 2015, plain white unmarked HGV cabs have helped police spot more than 51,500 offences on Britain’s motorways.
- And one reader wrote to us about a parked emergency vehicle that made her doubt her own eyes.
Back around 2010, a reader named Janet wrote to us about something she’d seen while walking her dogs on the beach at Morfa Bychan, near Porthmadog in North Wales.
On a quiet stretch of road nearby — where the limit had just been cut to 30mph — a fire engine was parked up. There are only a couple of houses along that road, and there was no fire.
But as she got closer, Janet saw what looked unmistakably like a camera positioned against the fire engine’s windscreen. A police car had passed her heading back to town minutes earlier.
“It’s bad enough watching out for the police,” she wrote, “without having to watch out for fire engines as well.”
We never confirmed that sighting, and we said so at the time. But if your instinct is that no force would ever hide a speed trap inside a vehicle you’d never suspect — the confirmed record says otherwise.
The Tractor, the Horsebox and the Hedge
Humberside Police have openly admitted to exactly this kind of operation on the rural roads of East Yorkshire.
Under Operations Achilles and Kansas, the force deployed speed cameras and officers with handheld speed guns concealed in a variety of stationary vehicles — including a tractor and a horsebox — and, for good measure, in roadside hedges.
Part of the reasoning was cost: buying a tractor and a horsebox worked out cheaper than running marked patrols.
The force says the operations target the worst offenders, with speeds in the high 90s and over 100mph recorded on 60mph country roads, and Drivers stopped further up the road once clocked.
Serious speeds, certainly. But once a force has established that a camera can legitimately live inside a horsebox, the line between enforcement and ambush gets very thin indeed — and the horsebox doesn’t know the difference between 100mph and 36.
The Lorry in Lane One Is Watching You
On the motorway, the disguise of choice is bigger.
Since 2015, National Highways has run Operation Tramline: a small fleet of plain white, completely unmarked HGV tractor units, loaned out to around 35 police forces across England and Wales.
A trained officer drives while a spotter films down into passing vehicles from the elevated cab — a view no patrol car gets. Marked units travelling behind then pull the offenders over.
The results speak for themselves: more than 51,500 offences spotted from those cabs since the scheme began. The most common catches are Drivers without seatbelts and Drivers on their phones — and roughly a third of the vehicles stopped are ordinary cars.
That anonymous lorry you overtook this morning may have had a camera pointing straight into your lap.

When Enforcement Stops Looking Like Enforcement
Put it all together and a pattern emerges. The camera van you can spot from half a mile away is only one face of modern enforcement — the rest of it is dressed as farm machinery, freight, and foliage.
Was Janet’s fire engine one of them? We’ll never know for certain. But fifteen years on, a camera in a parked emergency vehicle would barely make the list of the strangest confirmed hiding places.
For you as a Driver, the practical consequence is simple: you will almost never know at the roadside that you’ve been caught. The first you’ll hear of it is a NIP on the doormat, days or weeks later, from a stretch of road where you saw nothing but a tractor.
And that envelope is precisely the moment the case can still go either way. The prosecution must serve the NIP validly and on time, the device and the operator must have done everything correctly, and the paperwork has to stand up — whatever the camera was hiding in.
DriveProtect™ Members get that checked properly. The moment a NIP arrives, Members have direct access to a specialist Speeding Solicitor who reviews the case and advises them exactly what to respond, for a fraction of the normal cost of legal help.
