Road traffic – Regulation of traffic. The traffic authority's duty of securing the expeditious, convenient and safe movement of traffic, as set out in s 122 of the Road Traffic Regulation Act 1984, was not given primacy but was a qualified duty which had to be read with the factors in s 122(2) of that Act. Having considered all the relevant factors, the Administrative Court dismissed the claimant organisation's application to quash, wholly or in part, the defendant local authority's traffic regulation order on the basis that none of the grounds relied on by the claimant were made out.
