Questions
What should I do immediately after a DUI arrest?
Contact Petersen Law immediately for guidance on license protection and case strategy. We'll review evidence, challenge procedural errors, and represent you in court to minimize consequences.
Can a first-time DUI charge be dismissed?
Yes, we've secured dismissals for first-time DUI charges by challenging evidence validity and procedural compliance. Each case requires thorough investigation of breathalyzer calibration, officer protocol, and traffic stop justification.
How do you handle out-of-town clients?
We represent out-of-town clients remotely through court appearances and electronic communication. Most traffic cases don't require client attendance, and we provide case updates via phone and email.
What's the difference between DUI and negligent driving charges?
DUI charges require blood alcohol evidence, while negligent driving focuses on unsafe driving behavior. Our experience with both charge types helps determine optimal defense strategies based on evidence and potential penalties.
How do you protect driving privileges after a DUI?
We challenge license suspensions through administrative hearings and negotiate restricted licenses. Our experience with Department of Licensing procedures helps clients maintain driving privileges for work and essential needs.
What payment options are available?
We offer competitive flat fees for traffic infractions and transparent billing for complex cases. Payment plans may be available for extended legal representation in DUI or criminal defense matters.
