Quoting
Mr. Knowitall
You can file any lawsuit that you choose to file but, as your lawyer has almost certainly already told you, you are not going to get the DMV, the state or the police department to reimburse you for your legal fees from that hearing.
Given that you don't deny that the traffic stop was justified by your speeding, and admit that you failed to obey a lawful order from a police officer, it seems exceptionally unlikely that you'll be able to establish any sort of civil rights violation even if the prosecutor chooses to dismiss the obstruction charge, if that's what we're talking about. At this point, however, it's not even clear what charges remain pending against you -- you have not shared that information with us.
