The family of a biker killed on his first day of retirement by a 93-year-old motorist yesterday called for stricter rules governing older drivers.

Alfred Ross admitted causing death by careless driving and is thought to be the oldest person in the country to be convicted of the offence.

He shuffled into New Forest Magistrates Court in Lyndhurst, Hampshire, with a walking stick to hear his sentence yesterday.

Magistrates told him to raise his hand if he could not hear properly as he was fined £3750 and banned from driving for five years.

Ross pulled out in front of Jeffrey Bennett's Honda motorbike in Brockenhurst on October 8, last year.

Mr Bennett was so badly injured he died at the scene, just one day after his 65th birthday and his retirement. He had worked in the insurance industry then as a builder.

Outside court Mr Bennett's daughter Lucy and his partner Julia Mason called for tighter legislation for drivers over 70.

In a statement, they said Ross's sentence could not make their loss any more bearable. "What it has done, however, is highlight the existing legislation governing older drivers, which is grossly inadequate," they said.

"Currently, drivers who are more than 70 years of age are required to complete a form every three years and asked to declare any medical conditions. Only if they declare a medical condition are they required to have an examination by their doctor."

They said many elderly drivers were not honest on the form and that the Royal Society for the Prevention of Accidents wanted "serious consideration" for compulsory medical checks for older drivers.

They added: "Our situation begs the question: Why this is not in place already?' Surely, we need an immediate change in the law. I would also urge families of older drivers to address any concerns they may have about their driving abilities. You too have a responsibility if you think there is a problem.

"What happened to my father was entirely preventable. His death will always be devastating, but if it can bring about a re-evaluation of the current legislation and prevent this happening to another family, we will have some comfort."
