Tips from the experts: managing managed motorways

Driver training specialist IAM Drive & Survive is offering weekly motoring tips to drivers from its head of training, Simon Elstow. This week he is advising on managed motorways.

"Managed Motorways" is the term for variable speed limits, sometimes in conjunction with opening the hard shoulder to traffic at peak times. The IAM says that managed motorways are very successful: the first one was the M42 near Birmingham, in 2006, and it has shown a decrease in personal injury crashes of more than half, none of them fatal.
