R/V's are an exception for traveling the parkway north of exit 105. If you want, print out the statute and carry it with you in case you get an unaware Trooper. I have never heard of anyone having an issue with the 96" wide rule. The statute again pertains to construction/ commercial equipment and requires the company/operator to obtain permission and a permit for such travel.
All vehicles except cars, campers, omnibuses, and vehicles entitled to toll-free passage under N.J.A.C. 19:8-3.2 (Toll-free passage) are prohibited from the Parkway north of Interchange 105.
