Plans have been published by the UK's DfT (department for Transport) to change driving licenses for truck and bus drivers, as well as those towing medium-sized trailers.
The new legislation is part of a consultation on European standards for driver training, testing and licensing, that comes into force in 2013.
From that year, every truck and bus driver under 45 will undergo a medical assessment and renew their license on a three-yearly basis, replacing their photograph every 10 years.
