New Jersey Traffic Statute Guide
N.J.S.A. 39:4-119, explained.
A flashing red signal works like a stop-and-yield command. Flashing amber does not require a stop, but it warns of danger and requires caution.
The Rule
Flashing red and amber are not interchangeable
At flashing red, a driver must come to a complete stop before entering or crossing the intersection, then proceed only after yielding to intersecting traffic close enough to be an immediate hazard.
Flashing amber indicates danger and requires proceeding with caution. A citation alleging failure to stop must therefore prove red, not merely a flashing beacon, and the exact signal phase and lens matter.
What Must Be Proved
The charge is narrower than its label
- A traffic-control or beacon signal operated as a flashing mechanism.
- For the listed stop offense, the lens flashed red and the driver failed to stop before entering or crossing; a yield allegation also needs immediate-hazard traffic.
- For amber, the State must identify conduct showing failure to proceed cautiously.
MVC points: 2 for failure to stop at a flashing red signal. That figure comes from the current MVC schedule, not an old payable-ticket table.
Fine note: This section does not state its own dollar amount. This guide therefore does not present an old Violations Bureau payable amount as the current fine.
Evidence & Defenses
Details decide these cases
Lens and mode
Night video can wash out color. Signal records, daytime photographs, lane alignment, and witness vantage help identify the controlling lens.
Complete stop
Wheel movement, stop-line position, dashcam, and fixed landmarks are more reliable than a generalized “rolled it” conclusion.
Immediate hazard
For post-stop yielding, distance and speed of intersecting traffic determine whether the statutory hazard existed.
Separate the theories. A cautious pass at flashing amber is not a flashing-red stop violation, and a full stop does not end the separate duty to yield to an immediate hazard.
