- Only ride where a Legal Right of Way is established for Vehicular traffic
Confirm that no Traffic Regulation Order (TRO) has been applied that has rescinded that Legal Right of Way
For a simple broad overview of Byways Open to All Traffic (BOATs) in the UK there is this map...

A lower tech and cheaper option, if you don't have the actual paper OS map, is to use this website, which also displays OS maps...
The great thing about Streetmap over Bing is that you can print full A4 map sheets that can be fully previewed in a separate tab before printing. If you do use this approach please consider saving your maps each time for future use, to reduce wastage.
