Mudflaps 43. Sir T. Kitson asked the Secretary of State for Transport what consideration his Department is giving to the introduction of legislation to make it compulsory for heavy vehicles to fit mulfiaps in order to avoid unnecessary spray. Mr. Horam Most vehicles are already required to have protective bodywork or fittings to catch mud or water thrown up by the wheels. We are looking into the possibilities for more effective fittings for heavy vehicles but are not yet in a position to make proposals for regulations.
