IN his letter about motorway driving (June 25) Bill Collison says there is a grey area about middle-lane hogging and that is where the law is failing.

He seems to be very proud of his CPC licence (Driver Certificate of Professional Competence) but he does not seem to understand the rules of lane discipline on motorways.

The Highway Code clearly states "You should drive in the left-hand lane if the road ahead is clear. If you are overtaking a number of slower moving vehicles, it may (sic) be safer to remain in the centre or outer lanes until the manoeuvre is completed rather than continually changing lanes. Return to the left-hand lane once you have overtaken all the vehicles or if you are delaying traffic behind you. Slow moving vehicles should always remain in the left hand lane of the carriageway unless overtaking."

Mr Collison says that he travels to Scotland quite regularly and uses the outside and middle lanes often. On the M6 and M74 there are lengthy stretches of the left-hand lane where there is no, or very little traffic and that is where he should be.
