The whole investigation, read against its own record.
Comprehensive technical review of DUI, DRE, and impaired-driving investigations, from the initial driving evidence through arrest, chemical testing, and administrative processing. Available for written evaluation, attorney consultation, hearing preparation, and expert testimony.
Independent analysis, not a manufactured opinion.
The evidence is assessed against applicable training, published procedure, scientific principles, and the record as it actually exists. Where the State's evidence is strong, that is identified candidly. Where the investigation departs from standard, that is explained precisely.
Counsel receives analysis that holds up under scrutiny, which is the only kind worth carrying into a hearing or a courtroom.
A holistic review of the investigation, from start to finish.
DUI investigations are intended to develop progressively, with each phase informing the next. Legal Limit Consulting evaluates the case in the same sequence, allowing the evidence to be assessed both individually and in the context of the investigation as a whole.
The exact scope is tailored to the evidence available and the issues presented in each case.
- 01
Vehicle in Motion
Review of the reported driving behavior and events leading to the stop, including what the officer observed, what the available video actually shows, the basis for the traffic stop or detention, and whether the driving evidence meaningfully supports an impairment inference, measured against NHTSA recognized impairment indicators.
- 02
Personal Contact
Evaluation of the officer's observations after contact with the driver, including speech, coordination, demeanor, odor observations, divided-attention behavior, statements, and other reported signs of impairment. Where body-worn or dash-camera footage is available, those observations are compared directly against the written report.
- 03
Pre-Arrest Screening
Review of the investigative steps used before the arrest decision, including Standardized Field Sobriety Tests, HGN, Walk-and-Turn, One-Leg Stand, preliminary breath testing, PAS and PBT evidence, officer instructions, test administration, clue interpretation, physical or medical limitations, and the overall evidentiary basis for the arrest decision.
- 04
Drug Recognition Expert Evaluation
When applicable, independent review of the DRE evaluation and resulting impairment opinion, including administration of the twelve-step process, observations, vital signs, eye examinations, psychophysical testing, toxicology, consistency with the DRE matrix, alternative explanations, and whether the ultimate opinion is supported by the complete record.
- 05
Administrative Processing
Review of the post-arrest investigation and chemical testing process, including evidentiary breath and blood testing, timing, observation requirements, instrument or procedural records when relevant, blood draw and chain-of-custody issues, toxicology, implied-consent procedures, and comparison of the chemical evidence against the rest of the investigation.
- 06
Conclusion & Litigation Strategy
Each comprehensive evaluation culminates in a clear assessment of the record as a whole. The final analysis identifies the most significant strengths and weaknesses in the investigation, places individual deficiencies in context, and translates the technical findings into practical information counsel can use for case strategy, motions, negotiations, cross-examination, hearing preparation, or trial. Where the State's evidence is technically sound, that is identified candidly; where meaningful weaknesses or inconsistencies exist, they are explained and documented.
