A PETROL tanker overturned and caught alight on the N3 highway near the Gillooly’s interchange in Johannesburg early on Friday morning, injuring the driver. Germiston traffic officials said the accident happened at about 5am. The highway has been closed for mopping-up operations and should be re-opened at about 2pm. The driver, who broke a leg and is suffering from severe shock, has been taken to hospital. Officials said he probably lost control of the tanker while negotiating a bend. No other cars were involved in the accident.
