the outside of large groups should also carry lights and wear  reflective clothing.  6. Motorways.   Pedestrians MUST NOT   be on motorways or slip roads  except in an emergency (see Rule 271 and Rule 275).  7. The Green Cross Code.   The advice given below on crossing the  road is for all pedestrians. Children should be taught the Code and  should not be allowed out alone until they can understand and use  it properly. The age when they can do this is different for each  child. Many children cannot judge how fast vehicles are going or  how far away they are. Children learn by example, so parents and  carers should always use the Code in full when out with their  children. They are responsible for deciding at what age children can  use it safely by themselves.  A. First find a safe place to cross   and where there is space to  reach the pavement on the other side. Where there is a  crossing nearby, use it. It is safer to cross using a subway, a  footbridge, an island, a zebra, pelican, toucan or puffin  crossing, or where there is a crossing point controlled by a  police officer, a school crossing patrol or a traffic warden.  Otherwise choose a place where you can see clearly in all  directions.
