Blood Testing & Implied Consent in New Jersey

Seek Help From a Skilled Parsippany DWI Lawyer

There is an implied consent law in New Jersey. That means at the time of obtaining a driver's license and signing for it, the driver also consents to submit to chemical testing for a suspected DWI. If an officer has reasonable cause to pull over a driver for driving under the influence, the driver will be asked to submit to a test. If the driver refuses, he or she could be subject to jail time, fines, and installation of ignition interlock device (IID) for between nine and 15 months (indefinite driver's license forfeiture until IID is installed).

Blood and urine tests are not always accurate. If you or a loved one faces DWI charges, contact a Parsippany DWI defense lawyer whether you submitted to a blood test or refused. The Law Offices of Christopher G. Porreca, P.C. defends all types of criminal cases and is knowledgeable in the area of DWI law.

Blood Test Challenge

A blood test that indicates the driver has a blood alcohol content (BAC) level of .08% or more means that the driver is considered incapable of safely operating a motor vehicle. For commercial drivers and those under the age of 21, the BAC level allowed is .04%. A DWI conviction can bring substantial penalties that include large fines, jail time, increased insurance rates, license suspension, and other repercussions.

When so many areas of your life could be affected, it is important to have a persuasive and professional defense to challenge the evidence from blood testing. There is a standard of protocol when taking blood samples. Some actions that can affect accuracy are the qualifications of the individual administering the blood test.

The use of a non-alcohol swab on the area of the body where the blood sample was taken is required. The vial for the blood must contain anti-coagulants and the sample must be handled correctly under controlled conditions. A defense has the right to challenge any evidence for accuracy and the procedures that involve blood testing or any other aspect of your DWI case.
