Is my right hon. Friend aware that in many cases such reflectors as are carried by foreign lorries in accordance with their own national regulations are derisory in size compared with the excellent and conspicuous reflector plates carried by British lorries? If it is unacceptable for people to crash into the backs of British lorries, it must be equally unacceptable for people to crash into the backs of foreign lorries. Will my right hon. Friend think again?
