That is about the same as the A20 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 4 sensors on the A20.

Other trip lengths: 10 miles saves 2 min, 25 miles saves 6 min. Worked out from the average speed along the whole A20 at each hour, so a trip through its worst junction at rush hour loses more than this.
Questions about the A20 on a Monday
What is the best time to drive the A20 on a Monday?
On a Monday the quietest hour on the A20 is 06:00, when traffic averages 35 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 A20 busiest on a Monday?
The busiest hour on the A20 on a Monday is 08:00, averaging 31 mph, about 14% 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 A20 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.
