England’s extensive network of motorways are what keep us all connected. They are what keep the country moving, but motorways can also be incredibly frustrating, especially when drivers find themselves facing heavy delays.

With this in mind, the car insurance team at Comparethemarket has conducted research to reveal which motorways across the country have the slowest average speeds, and where drivers can expect to experience the longest delays.

The A308(M) is England’s slowest motorway, with average speeds of just 30.8 miles per hour
Considered one of England’s shortest motorways at just 0.6 miles long, the A308(M) in Maidenhead was also found to be one of the slowest motorways in England, with average speeds of just 30.8 miles per hour.

Following behind in second place is the A38(M). Despite its unusual layout, with three lanes each way that changes to a 4:2 lane balance at peak hours to deal with the extra traffic in and out of Birmingham, it registers one of the slowest average speeds of just 44.2 miles per hour.

As the only purpose-built road from the motorway to Bristol city centre, the M32 is also prone to heavy congestion and reaches overall average speeds of just 48 miles per hour. The M32 is home to one of the slowest sections of motorway in England, with the southbound section around Junction 3 reaching speeds of just 26 miles per hour on average.
