Jam sandwich (police car)

A thin amber sidestripe, fitted using fluorescent tape and vinyl sheeting, was first applied to vehicles of the East Sussex Constabulary in 1965, introduced on the recommendation of Chief Constable George Terry.

The slang was popularised on TV shows such as The Bill, The Sweeney and Minder; as well as spreading through the use of CB radio.

The "jam sandwich" first came into use with London's Metropolitan Police in 1978, first applied on a fleet of new high-performance Rover SD1 traffic cars.

In the Metropolitan Police, the term 'jam sandwich' now colloquially refers to the car's livery only, as worn by remaining older vehicles and public order carriers that have not yet been replaced.
