The sisters of a man flung from his car and killed in a road crash pleaded yesterday with motorists to wear their seatbelts.

Shabana and Farzana Wyaid, of Wood Green, Banbury, told drivers to belt up after an inquest into the death of their brother, Sajid Wyaid, delivered a verdict of accidental death.

Oxford coroner Nicholas Gardiner heard that the 27-year-old security worker and former Banbury School pupil, of Boxhedge Road, Banbury, would almost certainly have survived had he been wearing a seatbelt.

After the inquest, Shabana said: "I am so angry he wasn't wearing a seatbelt, I could have slapped him one. I would just say to other drivers, put your seatbelt on."

Mr Gardiner said: "Had he been wearing a seatbelt he would have been restrained within his vehicle and it's likely he would have suffered far less injuries. Passenger compartments are carefully designed to protect people in just these circumstances.

"I've yet to come across a case where a person had clearly suffered worse injuries as a result of wearing a seatbelt but I've come across many cases where the occupants have been flung from their cars when not wearing a seatbelt and they are far more liable to have serious injuries."

A notice from the police inviting Mr Wyaid to attend a course as he had been stopped while not wearing a seatbelt was found in the car.

The inquest heard that the father-of-two was driving along the A4260 towards Kidlington, near Shipton-on-Cherwell, before the accident in May last year. There were no witnesses, but experts said the speed of the car on the 50mph-limit road was likely to have been 'high' as the car had rolled 80 metres from where it left the road.

Mr Wyaid was taken by ambulance to the John Radcliffe Hospital in Oxford, but died of multiple injuries, including a fractured spine, the following morning.

Accident investigator Pc Gary Baldwin told the inquest: "It's highly likely that had he been wearing a seatbelt, the driver would have survived the accident."
