Think the government can make a rule like that.They made a rule that seat belts are compulsary,still people don't wear them,don't use cell phones while driving people still do.Don't drink to much and drive same thing people still do. My last stint at the club boat ramp saw a family go out in thier boat,mum,dad and three kids had a look in thier vehicle on the backseat you guessed it all the life jackets for the whole family. Yes they can make rules for wearing life jackets but how can it be policed.
