I did that once... going down our road when I was still in MI, with the kids in the car, there was a much smaller than yours turtle in the road, but still not tiny. I pulled over and stopped, got a sweatshirt out of the back of the car and threw that over it. Picked it up and carried it off the road.

When I got back in the car, Aidan asked what I'd been doing. I told him I didn't want the turtle to get hurt. I think I became his hero then, at least for the day.
