You never think it will happen to you. But each year hundreds of people find themselves or others in desperate situations on the hill.
It's vital you know what to do when these situations arise and Mountain Rescue wants everyone to know the answers to the following questions.
The questions are based on information given in Call Out Mountain Rescue - a Pocket Guide to Safety on the Hill written by MR England and Wales.
The book is available for �9.99 from book shops and outdoor shops or from the MR England and Wales website.
Once you have finished the quiz there is a prize question where you could win one of 10 steel 0.6 litre Oval Traveller Sigg bottles.
