How can an Expert Witness Help?


Expert witnesses can be a life-saver when undergoing criminal trials, especially a DUI trial. With the help of DUI expert witnesses, the court will ideally see a clear picture of the case, helping you to avoid penalties. It may make the difference between a guilty verdict and acquittal.

If you are facing DUI charges, your DUI lawyer may call on an expert witness to help explain how field sobriety tests and forensic toxicology work. These facts can be used to your advantage in DUI trials, especially if there were possible shortcomings or issues in the process when you were arrested.

In some DUI cases, your attorney may be able to use the information to get your case dismissed without even going to trial.

If you have been charged with a DUI, consult with an experienced DC DUI attorney to help protect your rights.

What Does a Law Enforcement Expert Witness do?


A law enforcement expert witness is a person who has knowledge or experience in law enforcement. They are often called to testify on behalf of the prosecution in criminal cases to provide an opinion on a particular matter.

The prosecutor may call on law enforcement officers to testify about the procedure for arrest and standardized field sobriety tests, the credibility of a witness, the validity of evidence, or other matters pertinent to criminal cases.

To be qualified as an expert witness, the person in question must have been employed by law enforcement for at least five years and have had experience with testifying in court proceedings.


Can a Police Officer be an Expert Witness for DUI?

A police officer can be an expert witness in a DUI case if they have enough experience and knowledge in the field. Officers are not required to have a degree or certification, but they must have completed an approved training program for DUI enforcement.

A law enforcement officer may testify about the operation of breath alcohol testing equipment, blood alcohol testing equipment, the administration of the breath alcohol test, and other aspects of the DUI investigation.

What is the Value of an Expert Witness?


An expert witness’s opinion can be given in the form of testimony or the form of a written report. They are often called upon to provide their opinions on complex technical matters, such as the validity of a field sobriety test.

The value of hiring expert witnesses is that their highly credible testimony may cast doubt on the prosecution’s case against you. Ideally, with their help and that of your DUI defense lawyer, you may be able to plead to a less serious offense or be acquitted of all charges against you.
