Helmet, no helmet.....your choice. Shouldn't be a law but as already mentioned, you give up the right to sue me unless it's absolutely my fault.
I was wearing a helmet and the helmet absolutely saved my life. My injuries were extensive, including a fractured eye socket, cheekbone, concussion, broken back, broken hip, four broken ribs, broken shoulder, ruptured spleen, kidney laceration and three dislocated toes.
It was his fault, without a doubt and four witnesses. The state minimum for personal injury in Rhode Island is 25K of which, I received about 8K after the shiest-er got his cut and my health provider got their third.
My hospital bill for 71 days, 14 of which in ICU, 21 in the rehab hospital and 16 surgeries was about 600K. My employers health insurance company paid all but about 10K of that.
Long story, short answer....BUY PERSONAL INJURY PROTECTION THROUGH YOUR OWN INSURANCE COMPANY! I now carry about 500K of PIP on my cars just in case and it's not that expensive.
I'll never ride again, 34 years of experience can't make up for one second of stupidity......
