I have seen the report to which my hon. Friend refers. It shows that the accident record of the A180 is lower than the average for that sort of road, but rather higher in terms of the number of accidents involving driver fatigue while travelling in an easterly direction towards the docks. That may have something to do with the nature of the road, the length of the journey or people not complying with the advice in the highway code. I will certainly draw the attention of the Highways Agency to the matter. A national study looking at counter-measures to combat tiredness is being conducted by the same Loughborough university team, which will take on board the points raised by my hon. Friend.
