Furthermore, New Jersey prosecutors are not inclined to treat you lightly. If you face charges for driving under the influence, please read on, then contact an experienced Mercer County DUI lawyer to learn if you will go to jail if you get a DUI in New Jersey.

Will You Go to Jail for a DUI in New Jersey?

In New Jersey, a person can go to jail for a DUI conviction. The amount of jail time depends primarily on whether the offense is a first, second, or third DUI, and whether aggravating factors were present.

New Jersey imposes escalating penalties for repeat offenses. However, a first offense can include jail time under certain circumstances.

Jail Time for DUI Offenses in New Jersey

  • First-offense DUI: Up to 30 days in county jail
  • Second-offense DUI: Between 2 and 90 days in county jail
  • Third-offense DUI: 180 days in county jail

Some of those days in jail may be reduced if you participate in a drug or alcohol rehabilitation program and/or are subject to other factors.

Factors That Can Increase DUI Jail Penalties

Certain aggravating factors can lead to enhanced penalties in DUI cases.

  • A high blood alcohol concentration (BAC) significantly above the legal limit
  • Multiple prior DUI convictions
  • Driving with a minor passenger in the vehicle
  • Refusing a breath test under New Jersey’s implied consent laws
  • Driving on a suspended license caused by a prior DUI

What Is the Legal BAC Limit for DUI in New Jersey?

In New Jersey, a driver may be charged criminally if they operate a motor vehicle while under the influence of alcohol, drugs, or other intoxicating substances.

Legal Blood Alcohol Limits

  • 0.08% BAC or higher for drivers age 21 and older
  • 0.04% BAC for commercial drivers
  • Any measurable alcohol for drivers under age 21

However, it’s important to understand that you can be arrested if you have a BAC below 0.08% if the law enforcement officer determines that your driving ability is impaired.

Other Penalties for a DUI Conviction in New Jersey

Aside from jail time, a DUI conviction in New Jersey can result in additional consequences that can impact your daily life, finances, and reputation.

Financial and Administrative Penalties

  • Considerable court fees and fines
  • Suspension of the driver’s license
  • Mandatory installation of an ignition interlock device once the license is restored

  • Higher auto insurance premiums
  • Possible loss of employment if driving is required for work
  • Mandatory attendance at the Intoxicated Driver Resource Center (IDRC)
  • Potential annual surcharges assessed by the New Jersey Motor Vehicle Commission

Long-Term Consequences of a DUI

  • Difficulty obtaining professional licenses or employment
  • Increased complications during future traffic stops or criminal matters
  • Potential impact on background checks

How Can a New Jersey DUI Defense Lawyer Help You Avoid Time in Jail?

A skilled Mercer County criminal defense lawyer might have any number of defenses to utilize on your behalf. The strategy your legal representative employs will depend on your unique circumstances. Because DUI cases rely heavily on technical evidence like breath results, field sobriety tests, and police procedures, identifying errors in how the stop, testing, or evidence collection occurred can, in some instances, lead to reduced penalties or dismissed charges.

Common Legal Defenses Used in Mercer County DUI Cases

  • Police lacked probable cause to initiate the traffic stop
  • Field sobriety tests were improperly administered
  • Breathalyzer equipment malfunctioned or was improperly calibrated
  • The officer did not have the proper certification to administer the breathalyzer testing
  • Evidence was mishandled, or the chain of custody was broken
  • The evidence gathered was obtained through an illegal search and seizure
  • Medical conditions or medication caused symptoms mistaken for intoxication
  • BAC rose after driving but before testing (called the “rising BAC” defense)
