Young Brunette Girl Shows Off Her Tan Lines Outside On Rocky Mountains

A "trucker's tan" is a variation of the farmer's tan where one arm from the sleeve downward is tanned significantly more than the other arm due to driving with the windows down. While named a "trucker's tan," such a tan line is not exclusive to truck drivers and can be attained by driving most motor vehicles. An "inverted trucker's tan" is when the passenger in a vehicle has similar tan lines as a trucker's tan, but on the opposite arm.
In Britain, this tan is sometimes known as a "white van-man tan", since people in professions such as building, plastering, or plumbing tend to have this tan, and a "white van" is their most commonly used vehicle.
