According to a fatality crash summary, 40-year-old Delayne Renner was behind the wheel of a GMC Terrain and had just crested a hill when she failed to negotiate a left-hand curve and entered the median.

"The GMC clipped a delineator post and drove parallel to the roadway with the passenger-side tires in the median and the driver-side tires on the paved shoulder," the summary reads.

The summary goes on to say, "The GMC continued north until it impacted the end of a bridge rail. The GMC continued north across the bridge deck, where it rolled approximately 1 and 3/4 times, coming to rest on its driver's side facing west. During the crash, the vehicle caught fire and was completely burned."

It's unknown whether Renner was wearing her seat belt, and the summary didn't list any possible contributing factors.

This is the 57th fatality on Wyoming's highways in 2023 compared to 38 in 2022, 2021, and 2020, and 68 in 2019 to date, and the first fatality in Johnson County so far this year.

2022's Deadliest Wyoming County by Traffic Deaths

While car crashes can occur anywhere, some roads in Wyoming are more dangerous than others.

According to Wyoming Highway Patrol data, there were 117 fatal crashes in the Cowboy State in 2022 resulting in 133 deaths.

Of those fatal crashes, the majority (13.68%) occurred in Laramie County -- two in January, one in February, one in March, two in April, one in June, two in July, three in August, two in September, one in November, and one in December.

Sweetwater County saw the second most fatal crashes last year, 12, while Fremont and Lincoln counties each saw 10.

Albany and Park counties each recorded eight, and Campbell, Converse, and Natrona counties each tallied seven.

The deadliest 2022 crash in Laramie County took place on June 17 when two semis collided on Interstate 80 east of Cheyenne and immediately became engulfed in flames killing both drivers and a passenger.



Laramie County also saw two fatal crashes involving motorcyclists, two fatal crashes involving juveniles, and a fatal crash involving a pedestrian last year.
