This question has been considered in depth by an interdepartmental group which reported in November 1988 that they considered that wheelclamping should not be introduced at that time. Resources were to be concentrated instead on the development of a comprehensive tow-away service which, unlike wheelclamping, could address all of the various parking offences, including in particular the more serious ones.
Since 1988, there has been a significant increase in the numbers of vehicles which have been towed away for illegal parking. The introduction of wheelclamping is still an option if it is deemed to be necessary to supplement other enforcement measures.
