Failure to maintain lane is the kind of ticket most drivers have never heard of until they get one. On its own it’s a 2-point moving violation under N.J.S.A. 39:4-88. But this charge carries outsized importance for a different reason: drifting within or across a lane is the single most common justification police give for pulling a car over — which makes it the starting point for a huge share of DWI stops.
What the statute requires
N.J.S.A. 39:4-88 governs driving within marked lanes. In substance, it requires that a vehicle be driven as nearly as practicable entirely within a single lane, and that a driver not move from that lane until they’ve first determined the move can be made safely. A conviction carries a fine and 2 points.
Why this ticket matters more than its points
Two points is a modest hit by itself — though, as our NJ point system guide explains, points are cumulative and follow you to your insurer. The bigger issue is what often comes with this ticket. When failure to maintain lane is the stated reason for a stop that turned into a DWI or a drug charge, the lawfulness of that initial stop becomes a central legal question. If the alleged “weaving” wasn’t enough to justify the stop, everything that followed may be subject to challenge.
Where these cases get defended
- Was the lane deviation real and significant, or minor and momentary — the kind “as nearly as practicable” allows?
- Were there innocent explanations — potholes, debris, weather, wind, or an animal in the road?
- Does the dashcam or bodycam actually show the weaving the officer described?
- If a DWI followed, was the stop itself lawful — the threshold question that can determine whether the State’s evidence comes in at all?
Standing alone, it’s still worth handling right
Even as a simple traffic ticket, failure to maintain lane is a moving violation with points, and paying it by mail is the familiar plea-by-mail mistake. Many of these can be resolved to a non-point or reduced outcome, the same goal as a careless-driving plea-down.
