Florida has instituted mandatory minimum auto insurance requirements for all drivers, including commercial drivers. These are:
$10,000 Personal Injury Protection (PIP)
$10,000 Property Damage Liability Insurance
However, if your vehicle weighs more than 26,000 lbs., then you must carry at least the following combined limits of bodily injury/property damage liability coverage (per occurrence).
26,000 – 34,999 lbs: $50,000
35,000 – 43,999 lbs: $100,000
> 44,000 lbs: $300,000
Regardless of any coverage requirements, the benefits you will receive by investing in higher levels of coverage (even when it is optional) will ensure you have a high degree of protection available in the event of any particularly challenging vehicle mishap.
