Similar happened to a mate - old dear part crossed his path, he swerved going onto the verge and hit an item of road furniture writing his car off. Woman just drove off. He had a nightmare getting CCTV etc to track her down and she was charged on the last day of the 6 month window. WDC, leaving the scene of an accident - likely to have her licence removed!Keep death of the roads ?
Really should do it mate, your insurance may question why it's not progressed with the police and your payout may be lower or none at all.
Don't let lazy cops fob you off
