If you bring your own helmet can your visor be tinted or does it have to be clear??

any color visor is allowed

You can have any color visor for your helmet

My shield is a light smoke, and it wasn't a problem.

I'm not sure but it's best to call Naskart first to find out if they allow tinted helmet. They definitely have the clear glass helmets in different sizes.

I don't think it makes a difference

Doesnt matter
