Police in Utah are searching for a man they say attempted to flee a traffic stop on horseback

The problem is, the horse wouldn't move.

The Utah Highway Patrol stopped a car on Interstate 15 following reports of reckless driving. The trooper could smell marijuana in the car, and one of the women inside pulled some out of her shirt, which she gave to the officer, Salt Lake City TV station KUTV reported.

The woman and the driver were arrested.

Another man in the car ran across the highway in an attempt to elude authorities.

Highway Patrol officials say he may have attempted to escape the area on a horse, but the horse was "unwilling to aid the criminal," according to KUTV.
