In British slang, a jam sandwich is a police traffic or fast response car (as opposed to an ordinary panda car or patrol car).
The term came into common use in the 1970s, when such cars changed from the traditional blue and white colour scheme to white with a broad fluorescent orange stripe along the side. This colour scheme is reminiscent of jam sandwiched between two slices of white bread, hence the name. The slang was popularised on such TV shows as The Sweeney and Minder, as well as spreading through the use of CB radio. It is still in common use, although most forces now use different colour schemes with fluorescent stripes and Battenburg markings.
Famous quotes containing the words sandwich and/or jam:
“I tell people all the time, you have to be in love with that pot. You have to put all your love in that pot. If youre in a hurry, just eat your sandwich and go. Dont even start cooking, because you cant do anything well in a hurry. I love food. I love serving people. I love satisfying people.”
—Leah Chase (b. 1923)
“The rule is, jam tomorrow and jam yesterdaybut never jam today.”
—Lewis Carroll [Charles Lutwidge Dodgson] (18321898)
