My van failed its MoT a few days ago, so I’ve been doing the work myself to get it passed. I finished it today, but as I let it back off the jack it started rolling forwards and hit a parked car. I wasn’t driving it (the keys weren’t even in the ignition). After the accident I took it for it’s MoT and it passed, but the car it rolled into earlier wants to go through the insurance to get their car repaired. Will my insurance company pay out for their repairs?
