The DVLA website says that this vehicle has not had any tax since the 31st December 2014. So this vehicle has been driving illegally for 4 months. The tax disc (irrelevant) said 31st Dec 2014, which is when it last expired. I've seen this vehicle driving on the road nearly every day. Whether this is a DVLA bug or the vehicle genuinely has no tax, something is wrong. The vehicle is not SORN and has an MOT. The driver was a female and had 2 kids in the car, along with some horrible music playing.
