Thousands of motorists could lose Congestion Charge exemption

Jon Reay

Congestion Charge exemption has become a big target for car manufacturers. Get your cars' emissions under 100g/km and you'll find commuters flocking to your showrooms - letting them bypass Boris tax altogether.

Fortunately for buyers, this once-unique feature has become easier and easier to attain - nearly all manufacturers have a range of exempt models. Unfortunately for London, this means more and more cars are sneaking into the capital for free.
