Regulation 15 Smoke-free vehicles
A vehicle which is enclosed, and any part of a vehicle which is enclosed, is to be treated as being smoke-free if paragraph (2) or (3) applies.
This paragraph applies if the vehicle is one that is used wholly or mainly in the course of paid or voluntary work and it is used—
by more than one person (even if the persons who use it do so at different times or intermittently), or
to transport members of the public or a section of the public.
This paragraph applies if the vehicle is not within paragraph (2) and it is used—
in the course of paid or voluntary work and more than one person is present in the vehicle and one of those is present for the purpose of receiving goods or services from the person using the vehicle, or
for social, domestic or other private purposes and more than one person is present in the vehicle and one of those persons is a child.
A vehicle which is smoke-free by virtue of paragraph (2) is smoke-free all the time.
A vehicle which is smoke-free by virtue of paragraph (3) is smoke-free only when the vehicle is being used as described in that paragraph.
