HC Deb 26 June 1911 vol 27 cc229-30

asked what mechanical or other difficulty there is against compelling motor omnibuses to carry speedometers showing on large dials on the side of the vehicles the speed at which they are travelling; and whether he is aware that such speedometers can be obtained and, if kept in proper order, record the speed of the vehicle with reasonable accuracy?


The difficulty is to procure instruments which will record and exhibit the maximum speed attained with such accuracy and regularity as would enable their readings to be used as legal evidence against a person charged.
