I recognise some people may not of heard of route cards and may struggle to understand my description.
Here is a website that has a couple of examples
http://hsmt.info/route_cards.htmThe examples that are shown are very basic and mainly detail just the route or in a couple cases are specific to an organisations needs.
The more information you can add to your route card before you start a trip the less work has to be done by a person that may be looking for you or you have to do if and incident occurs.
