Wikipedia
"White van man" is a stereotype used in the United Kingdom for a smaller-sized commercial van driver, perceived as selfish, inconsiderate, mostly working class and aggressive. According to this stereotype, the "white van man" is an independent tradesperson, such as a plumber or locksmith, self-employed, or running a small enterprise, for whom driving a commercial vehicle is not the main line of business, as it is for a professional freight-driver.
The term white van man has been used as part of road safety campaigns by the Freight Transport Association.
White Van Man is a British sitcom that was created and was written by Adrian Poynton and first broadcast on BBC Three and BBC HD in 2011. It began screening in March 2011, becoming the highest-rated launch ever for a sitcom on BBC Three.
