I would think using your cell in this instance would be ok!! After all, you were reporting a potential wreck or someone getting killed. Now if you were "texting', that might be different. I can't drive and text too so have no idea how people do it! I can get in enough trouble just talking to a passenger in the car!
Oh, I hate when 2 racers get on the road. That is so very dangerous! I also don't understand the fast weaving in and our of traffic unless you have your flashers on and it's an emergency.
Yes, be Careful out there. Holidays seem to be the worse!
