As the new registration plates arrive on 1 September, can you spot the combinations the DVLA has banned on UK roads? The new 65 plates will be introduced to cars in the UK in September 2015, and all new cars registered between 1 September and 1 March 2016 will use the new registration plates. Dealerships are preparing for the launch with a host of new cars, from the new Fiat 500 to the Skoda Superb Estate arriving in time for the new plates.
