Some jurisdictions might have laws regarding:
* Safety glass: If the top is removed, are all necessary safety features (like side windows) present and made of safety glass?
* Windshields: Does the vehicle still meet legal requirements regarding windshields?
* Seat belts: Are all required seat belts functional and available?
* Vehicle inspections: Does the vehicle meet all requirements for inspection, which might vary based on the configuration with the top on versus off.
To know for sure, you need to check the specific vehicle code or motor vehicle regulations in your state, county, or municipality. Contact your local Department of Motor Vehicles (DMV) or equivalent agency for definitive information.
