As much as we love having in-helmet audio for music or communication purposes, we should be familiar with the local helmet laws, especially travelling across multiple states or provinces. The laws are made for our own protection and the safety of others, so they shouldn’t be ignored. When using helmet speakers be sure to use them responsibly and not turn up the music so loud as to the point where you can’t hear anything anymore.
Having said that, the guys over at Cycle Fish compiled a list of with 51 states where helmet speakers are allowed and where they’re prohibited.
In Canada, helmets may be equipped with speakers, but motorcyclists may not play music through them. Speakers can only be used as part of a communication device to allow drivers and passengers to communicate with one another.
