(1) The exit ramps at Junction 37 of the M6 are recognised to be 'high harm' spots. Several very serious collisions have occurred at the same location. Significant efforts have been made to address this, including by placing stop signs, increasing the visibility of signs, and improving driver awareness. However, the A684 remains the subject of the National Speed Limit. I was informed that no speed limit was imposed because previous investigation 'did not highlight a speeding problem'. The evidence I heard included an observation by the driver of the bus that: "At the point where I first saw the car, I was only a few metres away from the top of the slip road. The dark car was travelling up the slip road from my left-hand side. I must have only been aware of its presence for a matter of one or two seconds...I did not have any time to react or take any evasive action. As far as I recall I did not have time to brake or steer to try and avoid the collision." For the avoidance of doubt, the evidence indicates that the bus was being driven at less than the national speed limit. I am concerned that this indicates that the speed at which vehicles are permitted to drive on the A684, taken with the design of the junction, gives drivers insufficient time to react in the event that a vehicle crosses into their path.
