The following is taken from an email circular released by the DVSA:
The Driver and Vehicle Standards Agency is seeking views on proposals to:
allow drivers to take one test to drive both a rigid and articulated lorry, rather than having to pass a test in a rigid lorry first, and then another in an articulated lorry
allow drivers who want to use a bus or coach to tow a trailer to take one test with a trailer, rather than having to pass a test without a trailer first
allow the off-road manoeuvres part of the test to be assessed by the driver training industry
allow car drivers to tow a trailer without having to take another test
