What does ‘comparative negligence’ mean when determining who is liable for a Florida traffic accident?

“Comparative negligent assigned fault to each driver. In other words, if there’s an intersectional collision, there’s always an argument that one driver could have avoided the other, so if a driver’s turning left in front of you, could you have gone slower into the intersection and avoided that driver? Is the driver that’s turning left 90% or 75% at fault versus 10% to 25% for the driver that’s going straight? Is there a comparative negligence argument? Those are sometimes the most complicated cases that you need to develop the liability early in the cases so that you can get the best result for your client.”
