Another dump truck with a raised box hit a sign on the 401 near thickson. Driver noticed the hit and lowered their box while still at speed. Eventually pulled over. News has video, I didn't see an easy one I can link. No idea if they waited around for the cops or if they took off. MTO needs to start sending insurance companies a seven figure bill as a minimum every time this happens. The traffic impact is far more than that yet alone the emergency repairs.
