I know LA Legislature passed a "distracted driving" law a while back, but i think it really focused on cell phone usage while driving.
As with most anything in this state regarding law, guess we gonna have to wait til someone rear-ends someone else while having their dog jumping around their lap, nose out the window to get an answer.
but i agree, a good attorney will absolutely use this in the event there is not clear "liability". And if your insurance policy has a provision for "distracted driving" ( in lieu of say " cellphone use" ) then someone could be personally liable for damages.
