New Jersey Traffic Statute Guide
N.J.S.A. 39:4-128, explained.
Certain passenger, school, hazardous-cargo, commercial, slow, and low-clearance vehicles have affirmative railroad-crossing duties even without an approaching train. The vehicle category and posted crossing status are critical.
The Rule
Covered vehicles must stop, look, listen, and cross correctly
An omnibus designed for more than six passengers, a school bus carrying a child, a vehicle carrying explosive substances or flammable liquids as cargo, and commercial vehicles listed in 49 C.F.R. 392.10(a)(1)-(6) must stop 15 to 50 feet from the nearest rail, look and listen, then cross when safe in a gear that requires no shift; shifting on the tracks is prohibited. Abandoned, removed/paved-over, and officially signed Exempt Crossings are excluded under stated conditions.
Special slow or low-clearance equipment must notify the railroad, arrange protection, stop 15 to 50 feet away, look and listen, and cross only when safe and no immediate-approach warning is active. The low-clearance and 10-mph definitions in subsection (b) should be measured, not guessed.
What Must Be Proved
The charge is narrower than its label
- The vehicle, passengers, cargo, speed, or clearance placed it within subsection (a) or (b).
- The crossing was active and not within a statutory abandoned, removed, paved-over, or Exempt Crossing provision.
- The operator omitted the applicable notice, stop, look/listen, safe-crossing, gear, or warning requirement.
MVC points: 2. That figure comes from the current MVC schedule, not an old payable-ticket table.
Statutory penalty: Up to $50 for a first offense; for a second offense, up to $100, up to 30 days' imprisonment, or both.
Evidence & Defenses
Details decide these cases
Covered status
Seating design, actual school-bus passengers, cargo papers, placards, federal category, rated speed, axle spacing, and measured clearance determine coverage.
Crossing exemption
Official Exempt Crossing signs, abandonment records, rail removal, paving, warning-sign removal, and required notices must be verified.
Stop and gear evidence
Video, engine data, driver logs, and witnesses can show stop distance and whether the driver shifted while traversing the tracks.
For CDL operators, retain the inspection report, bill of lading, route records, and exact federal classification. A generic “commercial vehicle” label is not enough to identify the 49 C.F.R. category incorporated by this section.
Common Questions
Questions about 39:4-128
Must every commercial vehicle stop at every rail crossing?
No. The section identifies incorporated federal categories and other specific vehicles. Vehicle and cargo status must be checked.
What is an Exempt Crossing?
It is a crossing officially designated and marked “Exempt Crossing” by the Commissioner of Transportation; the stop rule in subsection (a) does not apply there.
May a covered driver shift gears on the tracks?
No. After stopping and determining it is safe, the driver must cross in a gear that avoids shifting and may not shift while on the tracks.
