Handling New Jersey DUI/DWI Cases Skillfully
New Jersey takes drunk driving charges seriously. A conviction on a first offense can result in a one year driver's license suspension, as well as excessive fines and increased insurance premiums. To fight a DUI/DWI charge, you need an experienced lawyer to defend you.
My name is John W. Hartmann. At my office in Princeton Junction, New Jersey, I represent adults and juveniles charged with DUI/DWI. Having practiced since 1994, I have the litigation skill and experience to defend you in court. Contact my office to schedule a free initial consultation.
Providing Careful Examination of Your Case
When building your DUI/DWI defense, I will thoroughly evaluate the case against you. I will question:
- Whether the arresting officer had probable cause for the traffic stop
- The accuracy of the blood alcohol level test
- If any procedural errors occurred that might grant you relief
- Your treatment at the police station
Many drunk driving cases have been dropped due to the inaccuracy of field sobriety tests or because the arresting officers failed to follow proper protocol. As your defense attorney, I will challenge all aspects of your arrest in order to identify any violation of your rights.
Former Prosecutor On Your Side
I spent 6 years as a municipal prosecutor before I became a criminal defense attorney. I have stood in the opponent's shoes. I understand how the opposition gathers information and prepares its cases. I also know how to find holes in the prosecution's case. I will use this knowledge when defending you.
