Lots of insurers will offer Driving other Cars BUT this is often limited to "older drivers" with well proven history.

Young, those with a bad driving record and /or recent licence holders are unlikely to have DOC on the policy.

Over the last 20+ years E-sure, Aviva & my current insurer LV covered DOC - only used it a few times to help somebody out.

This came up in our family three years ago when my father in law gave up driving so we needed to sell his car. We were selling through WBAC and we wanted to drive it to their site. All nine potential drivers, aged 30 to 65, were covered by their policies to drive other cars..Maybe things have changed since then but I suspect it’s still common.

What many people don’t realise though is that the car concerned must alsot be insured in its own right.

Likewise my LV policy has this feature.

But I always remember checking the policy before joining a car share scheme after a colleague was involved in an accident in which he was seriously injured and spent the rest of his life in a wheelchair.

He had been given a lift to work and the driver was involved in a head on accident.

When the claim was sorted , it turned out that the passengers weren’t covered and so the injured person had to claim damages from his work colleague, which involved care for the rest of his life and moving to a purpose built bungalow to be on one level.

I wasn't covered on my old policy by AGEAS, but I've just taken out a new policy with the RAC and I am. Curiously, it's underwritten by AGEAS. SWMBO, who's a named driver isn't.
