Are there parties other than the at fault driver against whom I can take legal action in a Florida?
The answer is there definitely may be. It may be something as simple as the owner of the vehicle that caused the accident who bears responsibility under the Dangerous Instrumentalities Doctrine, if they're in the course and scope of employment, and maybe their employer. If they have no insurance or not enough insurance, there may be an uninsured or under insured motorist claim. With all of these factors and many others, it's why it's so important to have an experienced attorney who knows where to look to find all of the possible claims.
