Turtles are not like squirrels on the roadway. People don't have to run over them and turtles don't dart in front of you leaving you no options. Pay attention when you drive and simply go around or straddle them. Better yet? Do as I do. Stop and help them across the road. take them to the side of the road they are headed toward. It is mating season. You wouldn't want someone to stomp you, just because you were crossing the road.
