Average speed cameras - Hmmm....

[Alan22]

Appreciate this is an old post but as its been resurrected I've wondered this for a long time with regards to average speed cameras......as they read registration numbers, can they differentiate between vehicle types as large vans for example I believe are restricted to 50mph compared to cars able to travel at 60mph. Would a large van doing 60mph be picked up as speeding in an average limit of 60mph. Same question would apply to any speed enforcement camera.

Having followed articulated trucks up the A9 to inverness I'd say probably not.

I suspect differentiation between vehicle size is based on data held by DVLA rather than any inherent detection method. What is more interesting is vehicles capable of towing but not necessarily towing one at the moment of its capture by the camera.
