New measurements are being introduced by the UK Department for Transport (DfT) to meet the new European requirements on driver testing, training and licensing.

The new criteria will focus on improving skills and safety for motorcyclists and drivers of lorries, buses and medium-sized trailers.

DfT confirmed the move in conjunction with the Driving Standards Agency and Driver and Vehicle Licensing Agency.

Under the new requirement the two categories of motorbike will be replaced with three and motorcyclists will have to take further tests to progress to a larger category.

It will also raise the minimum age of those allowed to use larger bikes without previous experience from 21 to 24.

For trailer towing, there will be limitations on the overall size of the vehicle/trailer combination.

New car and light van drivers will have to take further tests to tow a slightly larger trailer.

From 2013, under-45s who drive medium-sized and large buses and lorries will need to confirm medical fitness and renew their licence every five years.

The new demands also include compulsory initial qualification, periodic training and quality assurance checks for driving examiners.

The new European requirements are expected to come into force in 2013.
