What about "The Drunken Driver," which Molly O'Day also did? Great old mountain melody that would sound neat with double-thumbed banjo in GDGCD "sawmill" tuning.

Somebody on the old Folkways LP Mountain Music of KY (Banjo Bill Cornett?) is said there to have written a similar (or the same??) song about a drunk driver who runs over his own child. It's not on the LP but is mentioned in the notes booklet.

"Wreck on the Highway" was written by Dorsey M Dixon, of the Dixon Brothers, and was recorded by them in the late 1930s on the Bluebird label. Discographical notes on this are momentarily out of reach; IIRC it was reissued on vinyl in the 70s on a Dixon Bros LP. I think a 1960s remake is also on Dixon's Testament LP Babies in the Mill, which was recently being sold as a cutout at Daedalus Books.
