A few weeks back I mentioned on a thread that if I thought if you had a car accident during lockdown then you could have problems with your policy. I got shot down for scaremongering but now it seems the papers have picked this exact point up, originating from some lawyer I've never heard of admittedly but he says
“If you have an accident and can't prove your journey was essential, your insurance may be void.”

I still maintain that driving without a valid reason that can be proved is still a massive risk.
