General advice
Where there is a pavement or a suitable verge, use it. Where there is none, walk on the right hand side of the road, facing the traffic coming towards you, so that you can see what is approaching and step clear of it in time. Keep close to the side of the road, and be prepared to walk in single file on a narrow road or in poor light.
Never walk along the edge of the carriageway with your back to the traffic. That is the one position from which you can do nothing about a vehicle that has drifted wide.
At night and in failing light, make yourself easier to see. Brightly coloured clothing helps, and reflective material helps far more, because a driver's headlamps pick it up from well down the road while dark clothing gives them nothing to see until it is too late to stop.
Keep your attention on the road. Using a phone while walking along a road, or while crossing one, takes away the two senses keeping you safe. Do not venture onto the road at all if you are not in the right frame of mind to judge it.
Young children should not be out on the pavement or the road on their own. Go with them, hold their hands firmly, and keep yourself between them and the traffic.
Do not get onto, or hold on to, a moving vehicle.
