Ree Drummond's husband and nephew were involved in a collision near the family's farm in Osage County, Oklahoma, on Wednesday.

According to a report from the Oklahoma Highway Patrol obtained by PEOPLE, the collision took place around 1:43 p.m. on Wednesday about eight miles west of Pawhuska.

Ladd and Caleb Drummond were each driving a Himmat Fire Truck on County Road N3660. Caleb, 21, was driving southbound, while The Pioneer Woman star's husband, 57, was driving northbound. The trucks hit one another "head-on" due to "high winds on a gravel road" that caused visibility to be decreased, according to the report.
