The basic Car Insurance Requirements in Florida are as follows:

Liability Insurance is a minimum requirement and a low cost car insurance option as long as the vehicle is not financed.

The liability Minimums are 10/20/10 (Bodily Injury and Property Damage)
10/20/10 Explained:

The first 10 represents $10,000, the maximum coverage for one person's injuries, $20,000 for the total coverage for all injuries sustained in one incident and last but not least $10,000 for the property damage maximum coverage amount.

Florida Car Insurance Laws:
Insurance proof is a requirement at registration and of course after an accident. The First Offense Penalty Can be revocation of the drivers License-Registration.

How to handle an "uninsured and unregisted" mark with a citation:

I would like to discuss a story about a guy named Sal. a guy who took a risk. Living in the state of Florida he found himself getting pulled over for speeding. At the time he got stopped, his insurance had not been renewed yet. With the insurance renewed he registration was also not valid. The officer wrote up a citation for the speeding as well as no proof of insurance and registration. Since being stopped Sal went ahead and renewed his insurance and squared away his registration. With court coming up soon what should he expect? This is mainly up to the judge but seeing Sal take the steps to correct his mistake he should expect decreased fines. If he's lucky the Judge may eliminate all fines that have to do with insurance and registration, but the citation will be hard to avoid.
