HC Deb 05 February 1964 vol 688 c164W
79. Mr. Grimond

asked the Minister of Transport what steps are taken to ensure that distress flares are not used for purposes other than safety at sea.

Mr. Marples

Under the International Collision Regulations vessels are prohibited from using distress flares, except in cases of distress, and from using any signals which may be confused with distress flares.
