    M1 Motorway Traffic Reports

    Our M1 traffic reports cover the whole of the M1 motorway, from north London to Leeds. Each report shows where the problem is, which direction and junctions it affects, when National Highways last updated it and, where they give one, when it is expected to clear.

    How to find the latest M1 traffic news

    Our live M1 feed updates throughout the day with the latest reports on delays, roadworks, accidents, closures and congestion along the M1 motorway. Search by junction number and direction — northbound or southbound — to focus on the stretch you’re travelling, whether that’s the M25 interchange at Junction 6a, the M6 and A14 at Junction 19, or the approach to Leeds. A quick check before you leave can save you sitting in avoidable traffic.

    M1traffic.co.uk is dedicated to the latest M1 traffic news, checked every five minutes, 24 hours a day. The M1 meets the M25 at Junction 6a — see M25 Traffic, and Traffic News England for traffic news across all of England.
