After you were arrested you were given paperwork from the police officer. Included in this paper work was a temporary driver's license and information to contact the DMV. You only have 10 days to contact the DMV to request an administrative hearing. It is extremely important that you call and set up an appointment with the DMV so that your license does not become automatically suspended by the DMV.
Contact an attorney
You are being charged with a crime. For a first time DUI you can be sent to jail for up to 6 months. In addition you are looking at a potential license suspension from the DMV and significant fines and fees. Protect yourself and your family and retain a professional.
Detail all the information you recall from the arrest
The police will have and rely upon a police report at court. You need to do the same. Write down everything you recall about that day. Include information on any witnesses in your case. The more information that you have from the arrest the better your attorney will be prepared to defend your case.
