If your city and/or county does not have a WATV ordinance which allows you to drive your ATV or SxS on the streets, here is one approach to making it happen:
Basically you need to propose the idea to the city or county council members where you want to ride, try and find at least one of them who likes the idea to help you sell it.
Start by emailing the council/mayor with your interest (their email addresses are published on their website) and that you’d like to be the point of contact. Then put the word out on social media and get as many people as you can to also email them and express their interest in adopting the ordinance.
Once they’ve agreed to discuss it, talk to the city engineer and administrator about drafting up an ordinance (you can copy from another county and another city).
Then go to meetings, push the idea to keep it on the agenda, get other people to go to the meetings with you. Talk to people on social media who have done it in their area to get an idea what questions and concerns the council will have, and be ready at the meetings with those answers and examples from other counties and cities that have adopted ordinances. Try to keep momentum going until they either vote it down, or vote it into place.
