WALNUT CREEK, Calif. — That mustang in the rearview mirror turned out to be a real horse running on a Northern California highway — followed by a mule.

Commuters east of San Francisco on Monday were stunned to see a white horse and a brown mule running across Interstate 680.

Steve Burdo with Contra Costa County Animal Services says the animals broke through a fence about a mile away.

The pair adhered to the vehicle code and used an on-ramp to get on the highway.
