The A1(M) is busiest around 07:00, and at the sensors along this route it keeps moving: even in that hour traffic averages 61.9 mph.
Typical weekday pattern from 5 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.
