Is a police officer allowed to impound a minors car, without notifying the legal owner of the car?

I was pulled over for expired tags. I am insured under the car, but my insurance card was a little watered down, making the expiration date hard to see. The officer said he wouldn't accept it and called to tow my car. He did so without notifying my mom or dad, who are both under the title. I was just wondering if this is legal.
