ride it all as much as you want.
If any one questions you you can either tell them to eff off in which case you can carry on your way, argue about it in which case you'll spend twenty minutes trying to convince an arrogant cock that he's wrong (you'll fail - he's an arrogant cock), or you can just carry on riding and ignore the arseholes.
Either way just ride where you want. You will never, ever be fined or stopped by someone who actually has the power to do so.
