It is suggested you retain an attorney, clean up your driving record and car registration. Plead not guilty then go into court and have the attorney work out the case for you. Good luck.
You should get the car registered and inspected immediately, keep your receipts and records, and speak to an experienced traffic lawyer. Although the offenses carry no points or suspensions, you should discuss the situation with a lawyer so you can make an informed decision whether to fight the citations.
