HC Deb 19 June 1968 vol 766 c152W
Mr. Macdonald

asked the Secretary of State for the Home Department how many prosecutions there have been in the last 12 months for the offence of using portable red reflecting road accident prevention triangles which do not comply with the relevant British Standards specification.

Mr. Elystan Morgan

This is not in itself an offence. The use of unauthorised red reflecting triangles may nevertheless render the user liable to prosecution for offences such as obstruction. I regret, however, that the information requested is not available.
