Since July 2009 England introduced smoke-free laws applying to vehicles. Scotland, Wales and Northern Ireland already had smoke-free vehicle legislation in place.
Smoke-free vehicle laws affect drivers, as do references to smoking and driving in the Highway Code, which also carries some legal consequences.
As driver it’s your responsibility to prevent smoking in a smoke-free vehicle. Know what’s expected of you. Some employers may impose policies regarding smoking that go further than the law.
