HC Deb 31 July 1980 vol 989 c842W
Mr. Austin Mitchell

asked the Minister of Transport what is the accident rate per thousand vehicles for motor cycle messengers in London for that latest available year, compared with (a) other motor cycles, (b) cars and (c) cyclists.

Mr. Kenneth Clarke

I regret that this is not available, as information is not collected on the basis of occupation or purpose of motor cyclists.
