Two young drivers alleged to have turned the A40 into a one-way street were cruising but not racing, a jury has heard today.

Ian Lloyd, 22, of College Park, Neyland, and Jack Murdoch, 18, of Main Road, Waterston, are said by the prosecution to have been part of a convoy that used the downhill, single lane at Arnold’s Hill as a second overtaking lane going up hill.

Five drivers have already admitted charges of dangerous driving and will be sentenced in late December.

Lloyd and Murdoch deny that their driving was dangerous.

Claire Griffiths has told Swansea crown court how she was driving towards Carmarthen in the left hand lane at about 60 mph.

As the road turned into three lanes—two going up the hill and one coming down—she was overtaken by a stream of vehicles.

She then saw three cars “overtaking the cars that were overtaking me” by using the downhill lane and recognised Lloyd’s Honda Civic because of its personalised number plate.

She said she anticipated an accident was about to happen.

It did when a Citroen Saxo being driven by Scott Beavis, aged 21, hit a Seat Ibiza.

Beavis, of Skomer Drive, Milford Haven, has already admitted dangerous driving.

Stephen Rees, the barrister representing Lloyd, said 30 cars had set out from a car park in Haverfordwest as a cruise, but not a race.

The jury is expected to return verdicts later this week.

The other four to have entered guilty pleas are Edward Adams, 19, and James Adams, 22, both of Thornton Road, Steynton, Stephen Murray, 23, of Lawrenny Street, Neyland and Ieuan Power, 18, of Harbour Close, Neyland.
