The A12 is slowest around 07:00, averaging 31.9 mph against 64 mph when it is clear. Traffic is heaviest around 16:00.
Typical weekday pattern from 2 National Highways roadside sensors along the route, June 2026. Bar height is traffic volume, colour is average speed. Overnight hours carry too little traffic to judge, so they are shown as quiet.
The A12 is Essex and Suffolk's main artery, running from the M25 at Brook Street past Chelmsford, Colchester and Ipswich towards Lowestoft. It carries motorway-level traffic on a road that mostly is not one, so roadworks and junction collisions bite harder here than on the neighbouring M11.
