Expert Legal Witness Services in DUI

DUI expert witness provides services related to all aspects of general, clinical, and forensic pharmacology and toxicology. Expert legal witness services in DUI provide impartial evaluations concerning alcohol and drug effects, and the role of drugs, alcohol, and other substances in civil and criminal litigation. Frequently, they work with attorneys, insurance clients, and law enforcement agencies.

In cases involving drunk driving, driving under the influence of drugs or alcohol, DUI and DWI, the use of legal experts is extremely important. DUI expert witnesses know their field proficiently and can clearly explain high-level scientific processes in words that the jury can understand. The defendant’s attorney can call a DUI expert witness to discuss the idea that there are other possible explanations for the prosecution’s evidence that the defendant was drunk driving. Experts can talk about scientific aspects of being under the influence, chemical tests, field sobriety tests, accident reconstruction, and so on.

Chemical Tests – Possible flaws with both breath and blood tests can be discussed such as that the breath machine is not accurately calibrated or blood fermentation may have occurred and result to higher alcohol reading.

Field Sobriety Tests – If the field sobriety tests show no physical and no mental impairment, the person’s performance of field sobriety tests can be used to support the expert’s opinion that the defendant was not under the influence at the time of driving. An expert witness will testify that mental and physical impairment are extremely important because mental impairment constantly precedes physical impairment if a person is intoxicated.

Accident Reconstruction – It is essential that an expert witness on accident reconstruction can offer opinions regarding the mechanics of the accident, and regarding whether or not the accident was the fault of the impaired driver, the other party, or would have been unavoidable regardless of the impairment or non-impairment of the defendant.

Alcohol Level at time of Driving versus Alcohol Level at time of Breath/Blood Testing – This is an extremely technical aspect of any DUI case, and only an expert can explain it to a jury and thus, raise a reasonable doubt as to whether the motorist accused was beyond the legal limit at the time of driving.
