The NJ U-Turn Statute
N.J.S.A. 39:4-125, explained.
New Jersey does not ban U-turns. It bans them in four specific situations — and if none of the four applied where you turned, the charge is asking the wrong question. Points verified August 2026 against the MVC schedule.
What the Statute Says
The four situations that make a U-turn unlawful
There is no general prohibition on turning around in New Jersey. 39:4-125 makes the turn an offence only where one of these is true:
| Situation | The test |
|---|---|
| On a curve | The turn was made upon any curve in the highway |
| On a hill | The turn was made upon the approach to, or near the crest of, a grade |
| Poor visibility | Anywhere the view of your vehicle was obstructed within 500 feet along the highway in either direction |
| Posted prohibition | The highway was conspicuously marked with signs stating "no U turn" |
Only one of the four is written as a visibility test. The curve and the grade are prohibited as such — the statute bans the turn "upon any curve" and on the approach to or near the crest of a grade without asking how far you could see. The 500-foot rule is the express sightline test, and the fourth is simply a posted ban. Which one the State is relying on matters, because they are proved in completely different ways, and a good sightline is not an answer to a charge brought under the curve clause.
What Gets Examined
A charge built on geography
Unlike a speed case, nothing here depends on a device. A U-turn summons depends on where the turn happened — and that is fixed, documentable, and still there to be looked at. Was it actually a curve, or a straight with a bend further along? Where was the crest of the grade relative to the turn? What obstructed the view, and was it within 500 feet?
Where the charge rests on signage, the question moves to the signs: whether they were posted for the direction of approach, whether they were visible, and whether "conspicuously marked" fairly describes what a driver would have seen that day.
None of that guarantees an outcome, and this page does not suggest one. It does mean the facts of a U-turn case are unusually concrete.
Points & Cost
What a conviction carries
Three points on the MVC schedule. The section writes no penalty of its own, so the court fine comes from the Statewide Violations Bureau Schedule, which lists the U-turn offence at $86 — $141 in a Safe Corridor or construction zone.
Three points does not suspend anyone by itself, but it is half of the 6 points within three years that triggers the MVC surcharge — $150 a year for three years, plus $25 for every point above six — and it stays on the abstract for insurers to read. If you already carry points, a 3-point addition is worth taking seriously. The points list shows the rest.
Common Questions
39:4-125 questions we hear
How many points is an illegal U-turn in NJ?
Three. The MVC point schedule lists 39:4-125 (improper U-turn) at 3 points. It sits above the common 2-point violations and halfway to the 6-point line where the MVC starts charging its own surcharge.
Is a U-turn illegal everywhere in New Jersey?
No — and this is the part people get wrong. New Jersey has no blanket ban on U-turns. 39:4-125 makes the turn unlawful in specific circumstances: on a curve, on the approach to or near the crest of a hill, anywhere your vehicle cannot be seen for 500 feet in either direction, or on a road conspicuously marked with "no U turn" signs. A U-turn on a straight, open, unsigned road is not what this statute prohibits. That is a statement about 39:4-125 only — municipalities regulate their own roads by ordinance and signage, so a local rule can prohibit a turn this section would not.
What does the 500-foot rule mean?
The statute asks whether the view of your vehicle was obstructed within 500 feet along the highway in either direction. It is a visibility test, measured both ways, and it is the element most U-turn cases actually turn on. Where the turn happened, what the sightlines were, and what was blocking them are all specific, checkable facts rather than matters of opinion.
Does a "no U turn" sign have to be posted a certain way?
The statute says the highway must be conspicuously marked with signs stating "no U turn". Conspicuous is doing real work in that sentence — a sign that is obscured, turned, or absent from the direction you approached from is a legitimate thing to ask about rather than to concede.
Ticketed under 39:4-125?
Tell us where the turn happened and what the road looks like there. That is most of the case, and you will hear a straight read and a flat fee before you decide anything.
