Two days ago my kids and I saw a garter in the road in front of our house. Not unusual, they always seem to sun themselves out there. I moved this one into the grass next to the road and left it. Two days later it was in the same spot so I decided to bring it back to the house and see if it needed water.

The snake was strong, right through it's tail so I do not believe it had been run over. The snake is not responding the way others have. When you put it down it will just stay in one spot.

Any suggestions? What could I look for?
Thanks
Not looking to make it a pet, just want to see if I could help it along.
