Drivers have been warned that resting their elbows on an open car window actually carries a fine and some demerit points.

The reminder comes after police in Sydney told drivers that it is an offence for any body part to be outside of a door or window of a car while it’s moving.

The only exception to the rule is when giving a hand signal to indicate a changing of direction, slowly or stopping.

In New South Wales, it carries a $349 fine with three demerit points, while in Queensland it’s $298 fine (and three points.)

In South Australia it’s $244 with three points and Victorians will be stung $165 on the spot.

The laws are slightly softer here in WA, with a $50 fine and one demerit.
