That is about the same as the M20 runs on an average day. Hours outside 06:00 to 22:00 are shown but greyed: the small hours are the fastest on almost every road in England, which is true and useless for planning. Averaged across 19 sensors on the M20.

Questions about the M20 on a Monday
What is the best time to drive the M20 on a Monday?
On a Monday the quietest hour on the M20 is 19:00, when traffic averages 57 mph. That is a measured average from National Highways roadside sensors on the road itself, recorded between 1 May 2026 and 15 June 2026, rather than an estimate. Only 06:00 to 22:00 is considered, because the small hours are the fastest on almost every road in England and saying so helps nobody plan a journey. Roadworks, collisions and weather are not in the average, so it describes what this Monday usually looks like rather than what today will look like.
What time is the M20 busiest on a Monday?
The busiest hour on the M20 on a Monday is 11:00, averaging 54 mph, about 6% below the speed the road runs at when it is clear. The comparison is against this road's own free-flowing speed, so "slower" means slower than the M20 normally manages rather than slower than some national figure. Measured from roadside sensors between 1 May 2026 and 15 June 2026. It is an archive of the usual pattern, not a live reading, so check conditions before you set off.
