Live M1 Traffic Flow Map Now
How fast is the M1 moving right now? This live traffic flow map shows the speed on every stretch of the M1 from Junction 1 at Staples Corner in north London to Junction 48 near Leeds, where it becomes the A1(M), in both directions. Green is moving freely, amber is slow and red is very slow or stopped.
The map is a summary. For the full picture before you set off, see all the latest M1 traffic news, the overhead message signs showing on the M1 right now, and the speed limits on the overhead signs.
Untick all three to see just the speeds. We show the important overhead signs and the mandatory speed limits (red ring); see every overhead sign.
How to read the M1 speed flow map
North is at the top, so Leeds is at the top of the map and London at the bottom. The left-hand line is the northbound carriageway and the right-hand line is southbound, so you can see the traffic on the other side of the road as well as your own. Between Junctions 6A and 8 the map shows one stretch, as National Highways’ own data does. Junctions are spaced by the real distance between them, and the miles between each pair are shown on the left. Tap or click any stretch to see its speed and how recently it was measured.
The M1 is about 190 miles long, so use Show junctions to see only the part you are about to drive, and Colour the road by to switch between plain speed in miles per hour and speed compared with what is normal for that stretch at this time of day.
Services and connecting motorways
A red end on a junction sign with a knife, fork and fuel pump marks services. Connecting motorways, such as the M25 at Junction 6A, the M45 at Junction 17, the M6 at Junction 19, the M69 at Junction 21, the M18 at Junction 32, the M62 at Junction 42, the M621 at Junction 43 and the A1(M) at Junction 48, are shown in blue. Where we run a site for that motorway, a pointing hand shows the way you turn off; tap it to see that motorway’s site.
For every junction with the roads and places it serves, see the map of the M1 junctions.
Where the speeds come from
The speeds come from National Highways’ traffic data, which combines road sensors with vehicle data, and the map is refreshed every five minutes. Where no recent measurement is available for a stretch, the map shows the speed that is normal there at this time of day and says so when you tap it. Road closures reported by National Highways are shown in red with white crosses. Always follow the signs and signals you can see on the road.
