i do believe that earplugs ARE against the law in California. Don't tell them though because I'm getting ready to file a class action suit on behalf of all motorcyclists who have sustained hearing damage due to being law abiding citizens and refraining from wearing illegal ear plugs.
also thinking about another class action suit against California and naming all loud assed bikes with no baffles. If california would enforce laws on the books for loud assed mufflers (or lack of) on cars bikes and stereos -- OR allowed me to wear earplugs - my hearing wouldn't be as lousy as it is.
I hope to retire soon after the settlement.
The ordiance was modified a year or two ago to allow the use of 'custom fit' ear plugs, IIRC. Though a recent article in
Friction Zone by their motocop editor disputed that cuz he didn't have the updated regs...
Off to Google I go!
Edit: Yup, here's the
linky, so your suit won't hold water. Ear plugs are legal given the caveat in the law.
