A vehicle tracking company has found the slowest motorway in the UK is the M606 in West Yorkshire – where drivers manage an average speed of just 24.62mph.
Ram Tracking monitored the speed of vehicles using its GPS tracking software and discovered that many UK motorways fail to achieve an average speed of more than 30mph – less than half the 70mph national speed limit for UK dual carriageways and motorways.

Behind the M606, the M32 motorway in Bristol – which is set to have a 40mph speed limit introduced along a section of it next year – averaged just 26.15mph.
The M9 motorway in Scotland is also one of the slowest, with average speeds recorded at just 26.74mph.
The data also revealed that drivers along the M1 motorway along its entire length, from London to Leeds, average just 43.82mph. That’s 3mph more than the busy M6.
The firm behind the data supplies tracking software to commercial vehicles – so cars are likely to set a higher average speed when traffic is running freely.
RAM Tracking CEO Chris McClellan 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.”
