South Jersey DWI Lawyer Provides Blood & Urine Test Defense

New Jersey law enforcement has really cracked down on drunk driving in recent years. Most of the time, police officers will conduct a blood test when a suspected drunk driving accident results in serious injuries. Law enforcement also conducts blood and urine tests for DUI drug arrests. There are many variables that can affect the results of a blood or urine test so it’s imperative that you speak with an experienced attorney as soon as possible. A knowledgeable DUI attorney can look over the details of your arrest and protect your rights.

John Tumelty, founding partner of the Law Offices of John W. Tumelty, is a former prosecutor and Atlantic City DWI defense lawyer. He appears regularly in South Jersey courtrooms and protects the rights of clients charged with DWI offenses, including first offense DWI, underage DUI, and out-of-state driver DUI. Mr. Tumelty represents clients accused of drunk driving throughout the area, including Cape May County and Atlantic County.

What Are Your Legal Rights When You Are Arrested for a DWI in NJ?

In New Jersey, drunk driving offenses are addressed by N.J.S.A. 39:4-50. As set forth by the statute, a person is in violation of the law when their blood alcohol content (BAC) is above .08 percent. While BAC is typically measured via a breath test, it can also be measured by blood or urine tests.

It is important for you to know and understand your rights. You do not have to take a blood or urine test when requested by law enforcement. Beyond that, a police officer cannot mislead a driver into thinking that they are required to submit to a blood test. If you are stopped for suspicion of DUI in New Jersey, it is imperative that you speak with an attorney immediately. Do not make any statements or offer any admissions to police before first consulting an experienced DUI lawyer.

If you did consent to a blood or urine test, a skilled DWI defense attorney can potentially challenge the evidence. Blood and urinalysis tests are not conclusive. An attorney who has familiarity with, and working knowledge of, testing procedures can scrutinize the results of these tests and possibly get the evidence against you dismissed. John Tumelty understands the techniques used by law enforcement to gather evidence for a DUI case, so he will ensure that all protocols were followed with respect to maintenance and operation of the testing devices. For example, the machine used to test your blood or urine sample needs to be in perfect working order. If the machine was not properly calibrated or maintained, Mr. Tumelty may be able to get your blood test results tossed out in court.
