New Jersey Traffic Statute Guide
N.J.S.A. 39:4-90.1, explained.
A driver may enter or leave a limited-access highway only at an entrance or exit established by public authority. The State must prove both the highway's status and the unauthorized access path.
The Rule
Access is lawful only at officially established points
The section bars driving onto or from any limited-access highway except at entrances and exits established by public authority. It covers both entering and leaving.
The citation is not established merely because a maneuver used grass or a shoulder. Records and roadway design must show a limited-access highway and that the place used was not an established access point.
What Must Be Proved
The charge is narrower than its label
- The road was a limited-access highway.
- The driver entered it or left it at the charged location.
- That location was not an entrance or exit established by public authority.
MVC points: 2. 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
Highway designation
DOT maps, access-control plans, and official records prove limited-access status rather than assumption from speed or appearance.
Established point
Temporary construction exits, emergency crossovers, signage, and agency authorization can complicate whether access was established.
Necessity facts
A crash, medical emergency, officer direction, or disabled vehicle may explain the path and should be documented, even though the statute has no written emergency exception.
Save GPS and dashcam data and obtain work-zone plans. Current ramps and barriers may not match the layout on the ticket date.
Common Questions
Questions about 39:4-90.1
Does this include entering through an exit ramp?
Potentially, but the State must identify the direction and prove the actual access used was not an established entrance for that movement.
Is every highway with ramps limited access?
Not merely by appearance. Official status and access-control records can be important.
What if construction redirected traffic?
Temporary official routing can change the established path. Signs, cones, project plans, and officer directions should be preserved.
