Sat Nav Tips
LISTEN: Carefully listen to the SatNav instruction.
LOOK AT SATNAV: Check the SatNav screen and gather the information, checking it against the verbal instruction (sometimes this differs). Also check the top box which gives forward planning information eg where you're going next say 250 yards away. The bottom box gives information like speed limit and name of road.
LOOK AT ROAD: Collect other relevant information eg. road layout, lane dedications, signs and surrounding traffic flow and other road users eg. pedestrians and/or cyclists.
PLAN: Having collected all available and relevant information, plan/decide what you have to do and carry out any lane changes carefully and safely using mirrors/signal/manoeuvre.
Hope this helps and good luck!
