Across the day that is roughly 2 percentage points closer to free-flowing than the M3's average day, so Sunday is one of the easier days to travel on this road. 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 12 sensors on the M3.

Questions about the M3 on a Sunday
What is the best time to drive the M3 on a Sunday?
On a Sunday the quietest hour on the M3 is 07:00, when traffic averages 63 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 Sunday usually looks like rather than what today will look like.
What time is the M3 busiest on a Sunday?
The busiest hour on the M3 on a Sunday is 12:00, averaging 61 mph, about 2% 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 M3 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.
