On 1st March at 8.15am, a Heavy Goods Vehicle (HGV) driver was enroute to Marmul to deliver High Density Polyethylene Duct. Three kilometers before Rima roundabout on a straight blacktop road, the HGV driver moved from his lane directly into the path of an oncoming 3rd party bus. Due to heavy fog in the area and reduced visibility, both drivers were unable to avoid the collision. The 2 vehicles impacted at an angle with the right side of the prime mover striking the right front corner of the bus in a glancing blow before the bus collided with the trailer headboard and both vehicles came to a stop at the right-hand side of the road in the northern direction lane. Consequently, 5 passengers in the bus sustained injuries.
