Impaired Driver Crashes:
Consulting & Expert Witness Services
7 Arrow Forensics provides case analyses, expert witness testimony, and litigation support on cases involving drug and alcohol impaired driving crashes.
Common questions arising in these cases may include:
- Is there adequate evidence to support the conclusion that the at-fault driver was under the influence at the time of the crash?
- In cases of a deceased at-fault driver, does the post-mortem forensic toxicology report, along with other evidence, support concluding that the crash was caused by drug or alcohol impairment?
- In untested at-fault driver cases, can evidence from attended drinking establishments help estimate a BAC at the time of the crash?
- What range of behaviors could be expected from a person given specific forensic toxicology test results or scenarios?
- Is evidence in the case adequate to support forward or back extrapolation (a.k.a. retrograde extrapolation) of BAC to assist in litigating elements of the case?
A DUI accident expert witness may help answer such questions. When working with 7 Arrow Forensics, clients can expect an expert who:
- Has personally examined and evaluated numerous persons under the influence of alcohol and other drugs.
- Has administered alcohol dosing labs, utilizing various dosing models to achieve target BACs, administered clinical and psychophysical tests, and recorded subsequent alcohol elimination during evaluation periods.
- Has a master’s degree in Clinical Toxicology and has completed industry leading training from the Center for Forensic Science Research and Education on forensic pharmacology, applied pharmacokinetics, pharmacology for the forensic toxicologist, alcohol and highway safety: testing, research and litigation, and on the effects of drugs on human performance and behavior.
- Has trained law enforcement officers, toxicologists, attorneys, and judges on matters of civil and criminal litigation of DUI crashes, standardized field sobriety testing, and other related areas.
- Has instructed all levels of the National Highway Traffic Safety Administration (NHTSA) curricula on sobriety testing, including: Standardized Field Sobriety Testing (SFST), Advanced Roadside Impaired Driving Enforcement (ARIDE), and Drug Recognition Expert (DRE).
