The ones marked in Yellow are the ones I hear about riders getting fook'd with....so here is is...you can have a 1 earphone in.....but there is no earplug restrictions > WTF is that...but good to know.....also the exhaust is measured from the center lane of travel...so if you get pulled over....the ticket has to say that you were in the center lane of travel when they pulled you over for loud exhaust...if it doesn't say that and there are more them 2 lanes in the direction you are traveling then you can get out of the ticket.....
