If you are going to the Lakes don't just rely on the map go to the National Park site
Lake District National Park Authority - Green Road Driving
Read all the advice on here and abide by that advice please. The Bobblies have a field day with people who ignore whats on here, Dave Robinson the Trails Advisor is a nice guy and very helpful if you ring them. Gatescarth Pass is very restricted now with a permit system operating and a 100 inch wheel base restriction. A gang from Liverpool LR Club, Glass and TRF have just repaired the UCR in Grizedale forest accessed West to East from the visitor Centre end a really nice route with some interesting rocky bits you will spot the repaired area as there is no big puddle now so Dave gets no grief from the Bobblies. Be aware though if it's a busy day you may find Kankku using this route the wrong way against all advice
