The NJ Marked Lanes Statute
N.J.S.A. 39:4-88, explained.
"Failure to maintain lane" and "unsafe lane change" tickets are both written under this statute — and it only applies at all when the road has clearly marked lanes. What each subsection requires, the surprisingly steep fine, and the CDL trap. Figures verified July 2026.
What the Statute Says
Four rules for marked lanes
| Subsection | The rule |
|---|---|
| (a) | Drive in the lane nearest the right edge or curb when it's available — except when overtaking or preparing a left turn |
| (b) | Stay as nearly as practicable within a single lane, and change lanes only after first making sure the move can be made safely |
| (c) | On a three-lane road, use the center lane only to overtake, prepare a left turn, or when it's allocated and signposted for your direction |
| (d) | Obey designated slow-traffic and speed-designated lanes where they're signposted or marked |
The threshold matters: the statute governs roadways divided into clearly marked lanes. Most tickets cite (b) — the drift or the lane change — and (b) contains two real elements: "as nearly as practicable" is a standard that tolerates some imperfection, and the safety check applies to the moment of the movement. What the officer saw, for how long, and why, is where these cases are decided.
Points & Money
What a conviction carries
| Consequence | Amount |
|---|---|
| MVC points | 2 |
| Payable fine (includes court costs) | $186 |
| Payable fine in a Safe Corridor, construction zone or 65-mph area | $291 |
| CDL holders | Must appear in court |
Statewide Violations Bureau payable amounts, verified July 2026; base statutory fine $50–$200 (N.J.S.A. 39:4-203). The schedule makes this offense not payable by mail for commercial license holders.
Separate from the fine: points stack toward the MVC's 6-point surcharge ($150 a year for three years, plus $25 per point over six) and the 12-point suspension, and insurers read the conviction at renewal for years. Full schedule on our NJ points list.
Beyond the Ticket
The stop behind the summons
A marked-lanes observation is one of the common stated reasons police give for pulling a car over — and some of those stops become DWI or other investigations. In those cases, whether the driving actually violated 39:4-88 isn't just about 2 points; it can bear on the stop itself. If your lane ticket came stapled to something bigger, treat the whole file as one case.
On the ticket alone: most represented cases resolve in a conference with the prosecutor, many as amendments to lesser or no-point violations such as unsafe driving under 39:4-97.2 — a negotiated outcome, never an entitlement. In most routine cases an attorney can appear for you under Rule 7:12-3, so fighting it usually doesn't mean a day off work. The step-by-step of that court date is in our attorney-reviewed walkthrough.
Common Questions
39:4-88 questions we hear
How many points is a 39:4-88 lane violation in NJ?
Two points, for any subsection — drifting over a lane line, an unsafe lane change, riding the center lane of a three-lane road, or staying out of the right lane without a reason. The payable fine is unusually steep for a 2-point ticket: $186, and $291 in a Safe Corridor, construction zone or 65-mph area.
What does "as nearly as practicable" within a single lane mean?
That phrase is the heart of subsection (b) — and it is a standard, not a bright line. The statute does not demand laser-perfect lane keeping; it requires driving within a single lane as nearly as practicable, and moving from it only after checking the move can be made safely. How far, how often, and why a vehicle touched a line are all legitimate factual disputes.
Can CDL drivers just pay a 39:4-88 ticket?
No. The statewide payable schedule specifically makes this offense not payable for anyone holding a commercial driver’s license — a CDL holder has to appear in court. That is worth treating as an opportunity rather than a burden: the conviction lands on the driving record that your livelihood runs on, so the appearance is the chance to contest or negotiate it.
Why do lane tickets matter more than 2 points suggests?
Because a marked-lanes stop is frequently the doorway to something bigger — it is one of the common stated reasons for a stop that turns into a DWI or other investigation. Whether the observed driving actually amounted to a 39:4-88 violation can matter well beyond the ticket itself, which is a conversation for a lawyer, not a payment portal.
