Really need more in formation to answer this question. First, generally warrants are not issued on traffic tickets, they impose civil assessments instead of warrants. Need to know what jurisdiction . You should have been able to bail out of jail ater the arrest
It depends on many other factors, but it is quite possible to be held in jail the night you receive your second DUI. Having a warrant for failure to deal with the infraction is not taken lightly by the court. It's a sign of comtempt and disrespect so expect a difficult time from the court. My suggestion is to take care of the infraction ticket immediately.
The response above is not intended as legal advice since it’s impracticable to provide thorough, accurate advice based upon the query without additional details. It is highly recommended that one should seek advice from a criminal defense attorney licensed in your jurisdiction by setting up a confidential meeting. Moreover, this response does not constitute the creation of an attorney-client relationship since this message is not a confidential communication because it was posted on a public website, thereby publicly disclosing the information, which is another reason to setup a confidential meeting with an attorney.
