A criminal record can cause a lot of problems in life for many years after the crime occurred. Expungement is a legal process in which a person who has been convicted of a crime gets that crime cleared from his or her criminal record. The process involves petitioning a New Jersey Superior Court and meeting specific criteria. Once approved, all police, court and corrections documentation are removed from one's record. At this point a background check would indicate no evidence of the crime ever having happened.
When a driver is suspected of being under the influence of alcohol, an officer can utilize field sobriety testing to look for signs of impairment. Separately, a Breathalyzer or blood test may confirm if the amount of alcohol in the person's system is above New Jersey's legal limit of .08. In those instances, the person is charged with DUI. The process when someone is suspected of being impaired by marijuana is not so simple. The standard field tests, Breathalyzers and blood tests used to prove alcohol impairment cannot prove marijuana impairment.
