Motorists were treated to a spectacle last night as a convoy of decorated trucks lit up a busy motorway.

Around 250 trucks were out in force along the M25 on Saturday evening, putting on a light show by flashing their beacon lights as they travelledย in the slow lane at around 40mph.

The convoy of trucks left South Mimms Service Station between 6.45pm and 7pm, passing through Watford and onto Heathrow Chobham Services before circling back to South Mimms.

And the trucks did not go unnoticed, with plenty of people taking to social media to share their photos and videos of the convoy.

Videos show truckers driving along the M25 with their lights flashing, with one showing the convoy grouped closely together in a queue.

The convoy spectacle, which was organised byย Ian Lewton, was part of a fundraiser to raise money and support the Essex and Herts Air Ambulance charity.

MEC Grab Services, based in Watford, issued out eight of its heavy goods vehicle as part of the convoy.
