HC Deb 12 December 1979 vol 975 c654W
Mr. Austin Mitchell

asked the Minister of Transport how it is proposed to enforce the tachograph scheme, in a situation in which a driver keeps two discs and claims that another driver has just left the cab on the completion of his driving hours.

Mr. Fowler

The enforcement authorities, using existing powers, would no doubt take steps to satisfy themselves whether or not one tachograph record had been made by another driver.
