The court and the DMV are two separate entities. Although they're linked to some extent (the court will notify the DMV of convictions, failures to pay, failures to appear, etc.), they aren't perfect. Yes, the court should have sent an abstract to clear the case, but you can't be 100%.
As suggested, you can check with the DMV's mandatory action unit in Sacramento [call (916) 657-6525] to verify they know that your underlying case was dismissed. If for some reason it hasn't been cleared, you may have to go back to court and make sure they sent an abstract to the DMV electronically.
The above answer is for general information only and is based on the information you posted. Every case is fact dependent, so to get a thorough analysis of your situation, you will need to consult face to face with an attorney licensed to practice in the jurisdiction where the incident took place. Do not conclusively rely on any information posted online when deciding what to do about your case.
It should not be if it was suspended. However many things get lost so you will need to be proactive and contact the DMV’s Mandatory Actions Unit.
