Not that im aware of, but i am in the business use side- not personal lines - so im not sure in that regard.
I dont think it has reached a point where companies have taken on a "higher volume" of claims arising out of "distracted driving" that would prompt them to add this exclusion. But i havent read discount insurers policies ( like a GoAuto or The General ) so not sure.
And even if they do have, ambiguity in a policy NEVER favors a carrier in Louisiana lol.
