Each square or bar is one hour, shaded by how far below its normal speed that stretch runs. Hover or tap for the exact figure, or pick Table for every number.
MORNING RUSH HOUR
No clear rush hour
Weekday traffic stays within a few percent of normal speed at this time of day.
EVENING RUSH HOUR
16:00 to 18:00
Worst at 16:00, about 15% below normal speed on a weekday
The rush hour is the run of hours around the weekday peak that are at least halfway from the road’s usual midday level up to the peak. Rush hour times on every road.
Average speed at each day’s worst hour
Bars run from 0 to 56 mph, the road’s best daytime hour.
14 minsaved on a 50-mile trip
Other trip lengths: 10 miles saves 3 min, 25 miles saves 7 min. Worked out from the average speed along the whole A14 at each hour, so a trip through its worst junction at rush hour loses more than this.
On a typical stretch
52,700 a day
Both directions added together, averaged over 2025.
Busiest stretch, B1050 to Dry Drayton Rd/ Oakington Rd
106,000 a day
Lorries are about 15% of all traffic on the A14.
From the Department for Transport’s road traffic statistics for the 68 stretches of the A14 in England. “Typical” means half the road’s length carries more than this and half less. DfT counted 65% of these stretches in 2025 and estimated the rest from earlier counts. Contains public sector information licensed under the Open Government Licence v3.0.

Send this page on WhatsApp, Facebook or X and this card is the preview people see, so the answer travels with the link. Every figure on it is the same one this page shows, from the same National Highways sensors.
Each dot is one roadside sensor, placed at its nearest junction, so the line shows the order of junctions rather than distance. All 5 sensors are shown.
The hour to avoid is listed first because it is the one that actually varies. The clearest hour tends to be whichever end of the day you look at, so on most roads it lands on the last hour before the cut-off and says the same thing every weekday. Night is excluded for the same reason: 3am is fastest on every road in the country, which is true and useless.
The quietest daytime hour on the A14 is Sunday at 18:00, when traffic averages 56 mph. The next clearest hours are Saturday at 18:00, Sunday at 19:00, Sunday at 06:00. These are measured averages from National Highways roadside sensors on the road itself, recorded between 1 May 2026 and 15 June 2026, rather than estimates or predictions. Daytime means 06:00 to 22:00 here, because 3am is the fastest hour on almost every road in England, which is true and useless for planning a journey. Roadworks, collisions and weather are not part of the average, so this describes the road's typical rhythm rather than a forecast for any particular day.
The slowest daytime hour on the A14 is Wednesday at 17:00, averaging 44 mph, about 20% below the speed the road runs at when it is clear. The other hours worth avoiding are Wednesday at 16:00, Tuesday at 17:00, Thursday at 17:00. Because the comparison is against this stretch's own free-flowing speed, "slower" here always means slower than the A14 normally runs, not slower than some national average. Measured from roadside sensors between 1 May 2026 and 15 June 2026. It is an archive of what usually happens, so it cannot account for an incident on the day you travel.
At its worst hour, the A14 averages 53 mph on a weekend day against 46 mph on a weekday. So the weekend is the quieter time to travel, by roughly 7 mph at the worst point of the day. Both figures are averages measured from roadside sensors between 1 May 2026 and 15 June 2026, not live readings.
The hour to avoid moves through the week. On the A14 the slowest daytime hour is: Monday 16:00 (48 mph), Tuesday 17:00 (46 mph), Wednesday 17:00 (44 mph), Thursday 17:00 (46 mph), Friday 15:00 (46 mph), Saturday 10:00 (52 mph), Sunday 11:00 (54 mph). The busy hour is listed rather than the clear one because it is the figure that actually varies: the clearest hour tends to land at one end of the day on almost every road, so it says much less about this one. All figures are averages from National Highways roadside sensors between 1 May 2026 and 15 June 2026.
Every figure comes from National Highways roadside sensors, the WebTRIS network, which count vehicles and record average speeds on the carriageway itself. Readings between 1 May 2026 and 15 June 2026 were grouped by day of the week and hour, then compared against the road's own free-flowing speed. This is an archive rather than a live feed: it describes the pattern the A14 usually follows, and it does not know about a collision, roadworks or bad weather today. Always check live conditions before you set off, and never check them while driving. The underlying data is published under the Open Government Licence v3.0.
