asked the Secretary of State for Transport what repair and renovation works of the road surfaces and supporting structures are currently planned to be carried out, when and at what cost, to junction 6 of the M6.

The initial pass/fail rates for private operators' vehicles are similar to those for the NBC. An operator is permitted to carry out on the spot repairs on a vehicle which has failed for minor reasons. The vehicle is then given a "pass after rectification".

I must ask the hon. Member to await the promised interim report on the Midlands links viaducts which I shall shortly be placing in the Library of the House.

asked the Secretary of State for Transport for what reason traffic on junction 6 of the M6 was at a standstill at about noon on Monday 8 July; and whether he will make a statement.

A major accident involving three articulated tanker vehicles occurred near Bescott at 11.20 a.m. on that day. The northbound carriageway was completely blocked and the southbound carriageway had to be closed until danger of an explosion had passed. The queue of northbound traffic extended back to junction 6. Diversions were introduced as soon as possible and the carriageways were reopened southbound at 12.15 p.m. and northbound at 5.15 p.m. I commend the police and emergency services for their prompt action and efficiency in these difficult circumstances.
