You can go to small court

If you win judgment in small court, the other party must make payment on time as indicated on the judgment sheet. If he does not make payment or does not make a payment arrangement, you can inform the small court, and his driver's license will be suspended.

A judgment in small court related to auto accident is the most easily enforceable. I once won $600 judgment in small court. The other party, although poor, had to come to me to make payment arrangement of $50/month because he was afraid of license suspension.
