Busiest bank holiday traffic in ten years expected
08:03 , Tom PlaceDrivers have been warned to expect the busiest early May bank holiday weekend on the roads in a decade.
The RAC has estimated that 19 million leisure trips will take place by car between Friday and Monday, only slightly behind the record 20 million forecast for the same period in 2016.
This comes despite the recent surge in fuel prices sparked by the conflict in the Middle East.

Saturday is expected to have the heaviest leisure traffic, with particular congestion expected on the M5 from Bristol to Taunton as many people head to Devon and Cornwall.
