About motorways.me

A live map of crashes, closures and delays on Britain's motorways and major A roads, updated every minute.

Where the data comes from

• National Highways: lane and road closures set by the control rooms, and what the overhead message signs say (“REPORT OF COLLISION”, “STRANDED VEHICLE”). Also the planned overnight closures.
• TomTom: incidents, delays and queue lengths.
• TfL: disruptions on London's main roads.
• Traffic Wales: incidents on Welsh motorways and trunk roads.

When several sources report the same thing in the same place, they're shown as one incident with a timeline of what each said and when.

What the labels mean

• Collision: a source reports a crash. “Reported” means only the signs say so, which usually means the control room has had a call that isn't confirmed yet.
• Lane closure, cause not reported yet: lanes are shut by the overhead signals, but no source has said why.
• Broken-down vehicle: a stranded or broken-down vehicle.
• Obstruction or hazard: debris, animals, people or something else on the road.

Causes and injuries are only mentioned if a source reports them.

Alerts

@motorways.me on Bluesky posts crashes and stopped traffic on motorways, with updates in the thread until they clear. Message it a road, such as “M6”, for the last 4 hours on that road.

Is it official?

No. motorways.me is independent and isn't affiliated with National Highways, TomTom, TfL or Traffic Wales. Reports can lag behind what's happening on the road, so always follow the signs, and never use the site while driving.
