Metro Distributors -life endangering driving

One of Metro Distributors' super link trucks nearly took out my family today!!! I am not impressed at all!! We were travelling from Harrismith towards Johannesburg and there were roadworks so the speed limit was 60 and the one lane was closed. The truck came barrelling down at us at a very high speed and nearly hit us. He then proceeded to sit right on our bumper and flash his lights at us.. Seriously where are we supposed to go? He then nearly overtook us on a double solid white line. He had two wheels in the oncoming lane. This guy could have cost at least 4 people their lives today!! I think this is absolutely unacceptable! Action needs to be taken! If it wasn't for the offramp at Bergview Engen garage I surely think he would have hit us!
