A 63-year-old Mexico, Missouri man is in serious condition after his motorcycle struck a deer on Route C in Audrain County Saturday afternoon, throwing him from the bike and leaving him without a helmet at the time of impact. The crash happened just after 2:15 p.m. about 0.2 miles south of Audrain County Road 132, according to the Missouri State Highway Patrol crash report.
Per the crash report, the man was riding northbound on Route C when a deer ran into the road ahead of him. The motorcycle slid off the right side of the road before coming to a stop in the southbound lane, and the 63-year-old was ejected in the process, as first reported by ABC 17 News. MSHP Troop F, which investigated the crash, does not release the names of those involved in its reports.
State crash records list the man as not wearing safety equipment at the time of the wreck, according to Missouri State Highway Patrol records. Under Missouri Revised Statutes Section 302.020 and 302.026, riders 26 and older can legally forgo a helmet if they hold a full motorcycle license and carry at least $50,000 in health insurance benefits, a provision that has been in place since the state repealed its universal helmet mandate in August 2020.
A Pattern of Close Calls on Audrain County Roads
This is not the first close call for a local rider trying to avoid a deer. Just weeks earlier, on July 22, a 23-year-old Mexico, Missouri motorcyclist was moderately injured on Route FF in Audrain County after swerving to avoid a deer, losing traction, and sliding off the roadway. And in September 2025, a 44-year-old Madison man suffered serious injuries in a single-vehicle motorcycle crash on Route C near County Road 232, according to the Mexico Ledger's police and fire coverage — the same corridor where Saturday's crash occurred.
Helmet Law Changes Tied to Rising Deaths
The state's decision to drop mandatory helmet use for adult riders has coincided with a sharp rise in unhelmeted motorcycle deaths. Unhelmeted motorcycle fatalities climbed from 11 in 2019 to 73 in 2023, while total annual motorcyclist deaths in Missouri hit a record high of more than 170, per data from the Missouri Department of Transportation. Traffic safety advocates continue to study what role the 2020 repeal has played in that trend.
Deer Strikes Remain a Persistent Statewide Hazard
Deer-vehicle collisions are a familiar hazard across Missouri roads, and this crash fits a broader statewide pattern. Missouri ranks among the top 15 states nationwide for deer-vehicle collisions, recording 2,951 deer strikes in 2024 that caused four deaths and 420 injuries, according to MoDOT figures. Highway patrol data from 2024 shows a vehicle struck a deer somewhere in the state on average once every 2.98 hours, with 21.1 percent of those crashes occurring in urban areas even though rural roads remain the primary hazard zones.
Both MoDOT and the highway patrol caution drivers and riders never to swerve abruptly when a deer appears in the road, warning that the maneuver often causes operators to lose control, roll into a ditch, or cross into oncoming traffic — collisions that can be far more severe than hitting the animal itself. In March, MoDOT completed a statewide Wildlife-Vehicle Collision Study examining 17,609 wildlife-vehicle crashes recorded between 2019 and 2023 to identify high-risk corridors and prioritize fixes such as wildlife fencing, modified bridges, and targeted culverts.
MSHP Troop F, headquartered in Jefferson City, oversees traffic safety, highway enforcement, and crash reporting across Audrain County and 12 other central Missouri counties. The condition of the 63-year-old rider had not been further updated as of the latest available report.
