In the last year 3 very similar incidents have occurred whilst vehicles were travelling on the road. In 2022 a heavy goods vehicle suffered a fire to the rear-front trailer axle (right side), in May 2023 a crane travelling to Fahud suffered a fire originating in the engine compartment and in June 2023 a lowbed trailer carrying a crane caught fire to the passenger side rear wheels.In all 3 of these occasions the fire could not be extinguished by the drivers using the on-board fire extinguishers. NO injuries were sustained, however the fire caused extensive damage to the equipment.
