England’s motorways, hour by hour

Every dot is a roadside sensor on a motorway or major A road. Pick a day and hour to see how far below its normal speed each stretch typically runs, measured between 1 May 2026 and 15 June 2026, not estimated. Today’s closures and incidents are marked on top.

What this map does and does not show

What do the colours on the traffic map mean?

Each dot is one roadside sensor, shaded by how far below its normal speed that stretch typically runs at the day and hour you have picked. Pale means it is moving at about its usual speed, and the deeper the shade, the bigger the drop. Closures are squares and London incidents are diamonds, so the shape carries the meaning too, not just the colour.

Which roads does the map cover?

417 sensors across 41 roads on the strategic road network: motorways and the major A roads. Ordinary local roads have none, and neither do Transport for London’s A roads, so those are never coloured here. London incidents from Transport for London appear as diamonds instead. A road that is not shown has no sensor data, which is not the same as being clear.

Is this map showing live traffic?

No. The colours are a typical week from the sensor archive, which runs a few months behind. They are not live traffic, and this site does not pretend to be. Closures and incidents are marked separately and are current. For live conditions, use a sat-nav. What this map is for is the opposite question: which hour to pick before you set off.
