Key Felony DUI Defense Questions
Use these points to understand what a defense lawyer should be reviewing before any major decision is made.
Was the police contact lawful?
A weak stop can affect the entire case. We review the stated reason for the detention, officer observations, body camera footage and whether the facts support reasonable suspicion or probable cause.
Can the chemical evidence be trusted?
Breath, blood and urine evidence depends on proper procedure. Maintenance, collection, storage, timing, lab work and interpretation can all create defense issues.
Is there a license deadline?
Many DUI matters create a separate DMV track. A hearing request, stay, restriction, IID issue or reinstatement requirement may need attention before the court case is finished.
What result best protects the future?
The right outcome is not always the fastest one. We consider dismissal, reduction, DMV relief, mitigation, trial posture, employment concerns and long-term record consequences.

What can make the case weaker for the prosecution?
In a Felony DUI case, prosecution problems may include an unlawful stop, unclear driving evidence, inconsistent officer reports, missing video, unreliable field tests, testing mistakes, weak toxicology interpretation or mitigation that changes how the case should be resolved.
What should be done before negotiating?
Before negotiation, the defense should review discovery, confirm DMV status, identify missing evidence, check prior history, evaluate legal motions and understand the client's work, school, immigration-sensitive, licensing or family concerns.
What facts can help reduce penalties?
Helpful facts may include voluntary education, treatment, clean prior history, employment, family responsibilities, medical context, restitution efforts, proof of insurance, community support and evidence that the police version overstates the conduct.
