Not on the limit

ARE any HGV drivers aware (Letters, August 16) that the speed limit on dual carriageways, such as the A14, is (for them) 50mph? Why is this limit neither observed nor enforced? Surely, if it were, the congestion caused by overtaking lorries would be great

Why is this limit neither observed nor enforced? Surely, if it were, the congestion caused by overtaking lorries would be greatly reduced.
