The M606 has been named the slowest motorway in the UK, with an average speed of 24.62mph, according to RAM Tracking.

Using tracking software in commercial vehicles across the country, the average speeds were captured from the January 1, 2016, to June 30, 2016, from which the data has been split into the north and south of England. The data has been compiled to include both weekdays and weekends.

The slowest average speed for a motorway was the M606 at 24.62mph, followed by the M32 in south Gloucestershire (26.15mph) and the M9 in Scotland (26.74mph).

Chris McClellan, CEO at RAM Tracking, said: “This study has been beneficial for both us as a business as well as enlightening for customers.

“We have discovered some fascinating statistics that will continue to help businesses up and down the country, by showcasing the slowest motorways nationwide.”

Each tracking device records the geo-location of the vehicle and the speed of the vehicle.

McClellan continued: “RAM Tracking allows fleet managers to make decisions backed by powerful data to save them vital money on fuel consumption as well as boost productivity.”

Data from January to June has been investigated in more detail on a month by month basis, which can be seen through the graphic below.

    The M32's position as 2nd slowest motorway in the country is entirely due to the former Mayor's never-ending Metrobus roadworks.
