Sorry, but the removal and safe relocation (to a pocket or cubbyhole) of a pair of shades requires a stop, as does the changing of a visor. Both take very little time to do, and believe me when I tell you that many of us regularly change our visors while we're out. It's as simple as removing your helmet and flipping a catch.
I haven't asked the question of Michele but it may be important to know the prevailing weather conditions and the levels of light at the time of the accident.
But you'd still have to prove the tint-level of the visor and as one could only speculate as to it's legality, it'd be a futile exercise.
So, if it was anything other than a bright clear day, then a tinted visor would not only be a point of legality but will have been severly detrimental to the biker's ability to assess the hazards before him. Also, whilst some tinted visors have only a light tint, some carry an extremely dark tint and that could be a contributory factor in an accident.
How do you conclude that a tinted visor (what level of tint are you referring to in any case?) would (or could) be severely detrimental to a biker's ability to assess road hazards on "anything other than a bright day"? There's absolutely no objective basis for that statement, I'm afraid.
After all, there is a good reason why tinted visors are illegal.
Really? To the best of my knowledge, there is no credible evidence available to support your statement - the reasons cited to justify their illegality are ludicrous at best and many respected organisations have supported campaigns to have the law changed in ths respect. Most of the tinted visors you see out on the road are no less severe in their tint than a regular pair of shades (which are regularly worn by car drivers, regardless of whether it's a "bright, clear day" or not!). Many police riders use them too - even Plodd admits to it in this very thread. Tinted visors are definitely a safety feature if used appropriately during daylight hours.
I'm sorry, but I find some of your statements regarding tinted visors to be both unreasonable and highly questionable.
