A devastating accident in Anza, Riverside County has left one rider dead and another critically injured after a horse was spooked and bolted into traffic on State Route 371. The tragedy, which occurred on the evening of August 31, 2025, has sparked questions about who may be held responsible when accidents involve horses on public highways.
What Happened
According to the California Highway Patrol (CHP), a group of riders was traveling eastbound along the shoulder of SR-371 when two of the horses veered into the westbound lanes. A 70-year-old driver collided with the animals.
- Monique Morton, a 47-year-old Air Force veteran and mother of three, was killed at the scene.
- Another rider, a 34-year-old woman from Temecula, was transported to the hospital in critical condition.
- Both horses involved in the crash were killed.
- The driver was reportedly traveling at a reasonable speed and was not suspected of alcohol or drug involvement.
Witnesses told reporters that one of the horses had become “spooked” shortly before entering the roadway.
Can the Driver Be Held Liable?
Based on CHP’s initial findings, it appears unlikely that the driver will face liability. Officers confirmed she was not speeding, impaired, or driving recklessly. In cases like this, motorists who strike loose animals are often treated as secondary victims themselves.

Horse Owners and Riders: Possible Negligence
California is a fenced-in state, which means owners have a legal duty to keep livestock and animals from running at large (Cal. Food & Ag. Code § 16902).
Key questions investigators may consider include:
- Did the riders take adequate precautions riding along a highway shoulder at night?
- Were reflective vests, lights, or other safety measures in use?
- Did the horse have a known history of spooking, and if so, was it reasonable to ride it in that environment?
If another owner or rider failed to act responsibly, there may be grounds for a personal injury or wrongful death claim.
Government Liability: A Tougher Road
In rare cases, government entities may face claims for a dangerous roadway condition—for example, if the highway was known for horse-related accidents but lacked signage or barriers. However, these claims face steep hurdles, including strict deadlines and broad immunity protections.
Legal Options for Victims
For Monique Morton’s family, the legal path forward may include a wrongful death claim. This type of lawsuit allows surviving loved ones to pursue compensation for the very real losses that follow a fatal accident — from funeral and burial expenses to the loss of financial support and, perhaps most importantly, the loss of her companionship and guidance. To succeed, they would need to show that another party’s negligence contributed to the tragedy, whether through unsafe decisions made on the ride or other preventable factors.
The surviving rider, who was critically injured, may also have the right to bring a personal injury claim. Her case would focus on recovery for medical bills, rehabilitation, lost income, and the long-term costs of an injury that could affect her life for years to come. As with any personal injury case, proving that another person’s negligence played a role is key.
It’s also important to remember that California follows the rule of comparative fault. In practice, this means that even if a rider’s own choices — such as riding near a highway at night — contributed to the accident, she or her family may still recover damages if another party’s negligence was also a factor. A jury can assign responsibility across multiple parties, ensuring that victims are not left without recourse simply because the situation was complex.
Why These Cases Are Complex
Horse behavior can be unpredictable, but that doesn’t eliminate an owner’s or rider’s duty of care. Cases often hinge on foreseeability: could a reasonable person have anticipated and prevented the escape? Evidence such as prior incidents, veterinary history, or unsafe riding practices may be critical.
