About the M1 motorway
The M1 is one of the UK’s busiest motorways, running around 194 miles from London in the south to Leeds in the north. It links major towns and cities including Luton, Milton Keynes, Northampton, Leicester, Nottingham, Derby, Sheffield and Wakefield, and connects with the M25, M6, M42, M69, M18 and M62. With heavy commuter, freight and holiday traffic across its 48 junctions, delays, roadworks and incidents are common — so it pays to check the latest M1 traffic news before you set off.
M1 Traffic gathers the newest M1 traffic reports and updates in one simple, mobile-friendly place, refreshed throughout the day, so you can plan your route and avoid the worst of the queues.
