Wisconsin Dells, Wis. (May 26, 1973) – The first fatality at the Dells Motor Speedway in its history happened Saturday night when Lyle Nabbefeldt, 38, of Nekoosa, was killed during time trials.
Nabbefeldt, a 14-year racing veteran, was killed almost instantly when his throttle on his late model Chevrolet stuck coming down the front straightaway.
The car struck the retaining wall, almost climbed over, took out a section of fencing, and landed upright.
It appeared as though Nabbefeldt’s seat belt broke, after striking the wall. He was rushed to a Baraboo hospital and was pronounced dead on arrival.
Drivers at the race donated the $2,200 purse to Sally Nabbefeldt, wife of the former driver.
The Dells track record was broke twice Saturday night as Jim Back of Vesper broke his own record of 14.541 seconds by lapping the track in 14.411 seconds.
Dick Trickle of Wisconsin Rapids won the 30-lap feature.
