Recently received a "Notice of Intended Prosecution" for travelling at 69mph on a dual carriageway part of the A303. I was pretty surprised to say the least, the offence was exceeding the limit for a goods vehicle. I browsed around the web a bit but didn't find a definitive answer as to whether a dualiner (or travelliner for that matter) is a car or a goods vehicle; it could be a car, but suggestion was that it also depends on use. Since I do not use the vehicle for trade - just like our old V-class - I thought it should be classed as a car for speeding. So herewith my experience for anyone with the same problem: After speaking to the "Safety Partnership" hotline, I wrote in explaining that the vehicle is not used for trade, and including photo's that showed the front and the numberplate, (that's all the speed camera guys see) the second window, and the second row of seats. Within a few days a letter of apology and withdrawel of NIP. BTW I had previously checked on the Severn Bridge as I typically prefer to go through the (car-only) automatic lane. They told me their rule is simple, and enforced by side facing cameras. If the vehicle has a window behind the driver's and a second row of seats, it's classed as a car.
