A MOTORIST who collided head-on with a car and killed the driver after going the wrong way down a dual carriageway has been jailed.

David Pulsford was sentenced to 15 months' imprisonment after pleading guilty to causing death by dangerous driving at Aylesbury Crown Court.

He followed instructions from a sat-nav that told him to turn right onto the A413 at Gerrards Cross – despite apparently passing two signs telling him to turn left onto the bypass.

His Vauxhall Astra then hit Samah Suliman's Saab head-on.

Miss Suliman's car caught fire and the driver received fatal injuries. She died before arriving at hospital.

Pulsford was driving from Gerrards Cross to his home in Longmoor Avenue, Barnet, at around 11.40pm on July 25 last year when the accident happened.

He drove along the Woodhill Avenue slip road before joining the A413 on the wrong side of the carriageway after following instructions from his satellite navigation system.

Pulsford was sentenced to 15 months in jail by Judge Christopher Tyrer last Thursday.

Speaking after the sentencing, Sergeant Dominic Mahon, of the Thames Valley Police Roads Policing Department, said: “Satellite navigation systems can be a useful aid to drivers but they can also be a dangerous distraction.

“Mr Pulsford misunderstood his sat nav’s instructions and ignored the road signs that should have made him realise his error.

“If Mr Pulsford had been concentrating fully on his driving, this devastating incident could have been avoided and the Suliman family would not have lost their beloved Samah.”
