HC Deb 19 July 1978 vol 954 c300W
Mr. Walter Johnson

asked the Secretary of State for Transport if he will introduce legislation seeking to ban the use of flashing headlights on motorways and other main roads, providing heavy fines for offenders.

Mr. Horam

No. In some circumstances, particularly in noisy traffic, this is the most effective way by which a driver can alert others to the presence of his vehicle. However, as rule 113 of the Highway Code points out, headlamps should not be flashed for any other purpose.
