The M40 motorway was built in the 1970s to relieve traffic congestion along the A40, and it has been a major part of the UK motorway network ever since. It has a total length of 89 miles (143 km) and passes through Buckinghamshire, Oxfordshire and Warwickshire.

The M40 motorway is known for its high safety standards and low accident rates, thanks to the installation of average-speed cameras along certain stretches of road. The motorway has won many safety awards and is regularly cited as one of the safest motorways in the UK. According to Department for Transport figures, in 2018, there were only 7 fatal crashes, 27 serious crashes and 262 slight crashes reported on the entire M40 stretch.

However, despite its safety record, the M40 motorway can still experience traffic delays and congestion, especially during peak times and around busy junctions. That’s why we provide live traffic updates and travel reports for the M40 motorway on our website, so you can plan your journey ahead and avoid any unnecessary stress.
