Litter on motorways

That this House deplores the huge amount of litter on motorways, access road, junctions and verges; notes that there is a crystal clear legal obligation on National Highways to ensure roads are kept clear of litter; and calls on National Highways to act on this obligation, use motorway gantries to promote anti-littering messaging, ensure staff and contractors remove signs, sandbags and cones following roadworks in a timely manner and ensure contracts include financial penalties for not doing so.
