M1 Live Serious Incidents Now: J12 Northbound Exit Closed (Other)
The information we are receiving suggests the M1 J12 northbound exit is closed (other). It appears to have started at Fri 9 Oct, 21:00 (9pm). National Highways expects it to clear by 05:00 (5am).
This page features the incidents on the M1 that have a bigger effect than an ordinary delay: a sudden closure, a serious collision, a vehicle fire, or traffic that has come to a stop. For every report, including smaller ones and planned roadworks, see the latest M1 traffic news, and for accidents and breakdowns see M1 accidents.
Each item is our own conclusion. We can’t be at every junction, so we put together the reports and readings we receive, from National Highways’ incident reports, overhead signs and live speeds to reports from drivers, and say what they suggest is happening and when it started. Further down are the serious incidents we recorded earlier today, yesterday and over the last month.
