View hint

Traffic is passing you at speed. If the draught from a large lorry catches you by surprise, it could blow you off balance and even onto the carriageway. By facing the oncoming traffic, you can see approaching lorries and so be prepared for their draught. You’ll also be in a position to see any other hazards approaching.
