The common limited access freeway speed limit is 65 mph. However, shorter length freeways such as US 202, Route 15, Route 90, and Route 33 remain at 55 mph. In all 65 mph speed zones, the fines for speeding and other moving violations are doubled. Signs informing drivers of this appear after most 65 mph signs. Urban freeway speed limits are generally 50 to 55 mph. However, some freeways in urban areas retain a 65 mph speed limit such as the main line of the New Jersey Turnpike up to Exit 13 (Interstate 278), I-80 from the Delaware Water Gap (Exit 4) to the Passaic River (Exit 53), I-295 in the Trenton area, and I-78 from the Delaware River to the Newark border (Exit 55). Only the New Jersey Turnpike system, including the Eastern and Western spurs, the Newark Extension (I-78), and the Pennsylvania Turnpike Extension (I-95) have variable speed limits on their entire respective lengths.
