Short answer
In New Jersey, DWI and DUI generally refer to the same impaired-driving offense under N.J.S.A. 39:4-50. DWI means driving while intoxicated; DUI means driving under the influence. The label does not create a separate, lesser charge. The statute on your summons, the evidence, and your prior record matter more than the abbreviation.

Why do New Jersey websites use both DWI and DUI?
The heading of N.J.S.A. 39:4-50 is Driving while intoxicated. The Motor Vehicle Commission also uses DUI in its public information. Someone searching for a New Jersey DUI lawyer and someone searching for a DWI lawyer may therefore be looking for help with the same charge.
Do not import another state's distinction between the two terms into your New Jersey case. Read the actual statutory number on each summons. A refusal allegation, for example, raises a separate issue from the underlying DWI charge.
Does DWI apply only to alcohol?
No. Section 39:4-50 covers operation while under the influence of alcohol and specified drugs, as well as operation with a blood alcohol concentration of 0.08% or more. The method of proof and applicable consequences depend on the allegation. Calling a case DUI does not, by itself, tell you whether it concerns alcohol or drugs.
A breath-test number is not the only possible evidence. Read whether a DWI case can proceed without a breath result.
Is a New Jersey DWI a crime or a traffic offense?
The DWI offense itself is in Title 39, New Jersey's motor vehicle laws. That classification does not make it a minor ticket: the statute permits serious consequences, including jail in applicable cases. Separate charges arising from the same incident must be evaluated on their own.

Which details should you check on your paperwork?
- The statute and description on every summons, including any separate refusal or driving charge.
- The alleged incident date, municipality, and named court.
- The court appearance date and instructions for attending.
- Any test records, license notices, or orders you were given.
Keep the complete documents. A short label in an email or online case summary is not a substitute for the actual complaint and notices.
What should you ask before deciding how to respond?
Ask which charges are pending, what evidence supports each charge, which court date must be attended, and how prior offenses or license status could affect the case. The useful question is what the State must prove in your case, not which abbreviation sounds less serious.

Frequently asked questions
Is DUI less serious than DWI in New Jersey?
Not because of the label. Both terms generally describe the offense under N.J.S.A. 39:4-50; the actual charge and facts determine the issues.
Should I search for a DUI lawyer or a DWI lawyer?
Either term can help you find New Jersey impaired-driving information. Check that the lawyer handles the specific charges and court listed on your paperwork.
