[entwisi]

tinted visors are illegal if they don't pass the required amount of light.... HOWEVER, even bike cops agree its a silly law. On a bike we can't easily take off glasses if we enter a tunnel, on a bike we can flick a visor up dead easy. We also don't have sun visors or any other way of shielding our vision hence bike plod not enforcing the law unless you are beinga total prat. a lot of riders will carry a clear visor under teh seat in case they are caught out after dark etc. this also pleases most plod if they get stopped. definately a case of common sense should take precedence.

My helmet actually has a clear visor but has 'drop down' internal dark visor/glasses ( bit like a pilots helmet). works really well and is totally legal.
