asked the Minister of Transport whether any progress is being made in eliminating the differences in Regulations as to width, overhang, brake arrangements, and other details of motor cars in the Regulations of the country generally and those of the Scotland Yard authorities; and whether he has received any complaints from the Board of Trade and commercial car manufacturers that these Regulations prevent standardisation of products and lose us orders from abroad?

I understand that the Commissioner of Police of the Metropolis is introducing certain relaxations in the constructional requirements applicable to motor omnibuses, motor coaches and taxi-cabs licensed to ply for hire in the metropolitan area. The Commissioner as no powers with regard to classes of motor vehicles other than hackney carriages. I have not, so far as I am aware, received any formal complaints on the lines indicated in the last part of my hon. and gallant Friend's question.

Will this change with regard to commercial cars bring them more into line, with the Regulations of the Ministry of Transport, and has my right hon. Friend read Sir John Thorneycroft's speech?

No, Sir; I have not read Sir John Thorneycroft's speech, but I understand that as far as motor coaches and motor omnibuses are concerned the Commissioner's Regulations are now being revised in that direction.
