User: If my car is broken while I am riding on the Highway, what should I do?
Assistant: If your car is broken while you are on the Highway try to maintain calm and identify a safe place to park your car if possible and try to identify if it's an issue that you can continue driving or if the damage can be fixed like a flat tire.

In case the damage is unknown or dangerous to continue driving, try to call the Highway services to help you and contact your insurance company if you have one.
