M1 Traffic on Tuesdays
Tuesday tends to be an ordinary working day on the M1, which makes it a useful yardstick: if a Tuesday is slow, the cause is more likely to be an incident or roadworks than the calendar.
The charts compare the latest Tuesday with the one a week earlier and with National Highways' usual speed, so you can see whether a slow hour was a one-off. The cards name the slowest hour and the slowest stretch in each direction.
