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.

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.

Questions about the A45

When is the best time to drive the A45?

The quietest daytime hour on the A45 is Sunday at 06:00, when traffic averages 55 mph. The next clearest hours are Sunday at 20:00, Sunday at 21:00, Sunday at 19:00. 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.

When is the A45 at its busiest?

The slowest daytime hour on the A45 is Thursday at 08:00, averaging 30 mph, about 46% below the speed the road runs at when it is clear. The other hours worth avoiding are Friday at 16:00, Thursday at 07:00, Wednesday at 07:00. Because the comparison is against this stretch's own free-flowing speed, "slower" here always means slower than the A45 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.

Is the A45 quieter at the weekend?

At its worst hour, the A45 averages 49 mph on a weekend day against 33 mph on a weekday. So the weekend is the quieter time to travel, by roughly 16 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.

What time should I avoid on the A45 each day?

The hour to avoid moves through the week. On the A45 the slowest daytime hour is: Monday 07:00 (41 mph), Tuesday 07:00 (32 mph), Wednesday 07:00 (31 mph), Thursday 08:00 (30 mph), Friday 16:00 (30 mph), Saturday 11:00 (48 mph), Sunday 12:00 (49 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.

How are these times measured?

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 A45 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.
