A tow truck was called to the scene, and crews reported about five feet of damage to a guardrail on the right shoulder.

If you're involved in a crash on a freeway like this one, try to move to the shoulder if your vehicle is drivable and it's safe to do so. Turn on the hazard lights and call 911 to report injuries and initiate a response. Even if you feel fine, a medical check is worth it since some injuries, like whiplash, don't show symptoms right away.

Follow up with your insurance company promptly and keep copies of any reports filed.
