Burlington Counties and Route 54 in Atlantic County. The Route 33 Freehold Bypass section where it is a super two freeway is also 55 mph. Urban two lane roads in boroughs and cities are typically 25 mph or 35 mph. Residential streets at the municipal or county level are generally posted at 25 mph speed limits in boroughs and cities. However, they can be as high as 40 to 45 mph at the county level, less likely in municipal maintained roads. Generally, anything above 40 mph becomes uncommon. However, there are a handful of 45 mph residential stretches such as Terill Road in Scotch Plains and Woodbridge Avenue (CR 514) in Edison. All rural non posted roads have a speed limit of 50 mph, as per state law. School zones through urban and suburban areas on two lane roadways normally have a speed limit of 25 mph when children are present. However, this limit can be as low as 20 mph and as high as 35 mph in some areas. New Mexico Speed limits for all classes of roads and areas are set by statute in New Mexico, meaning that any changes to the state's speed limits would require a bill to pass both chambers of the Legislature and be signed into law by the Governor (or overridden by the Legislature in the event of a Governor's veto). With the exception of wartime, New Mexico had no default numeric speed limit until the early 1950s.

Primary highways in open areas had daytime speed limits of 70 mph and nighttime ones of 60 mph. Secondary highways in open areas had daytime speed limits of 60 mph and nighttime ones of 50 mph. Before the end of federal speed controls, the maximum speed limit was 65 mph on Interstate routes and 55 mph elsewhere. In May 1996 legislation enacted by Governor Gary Johnson raised the absolute speed limit in New Mexico to 75 mph. Signs are posted on the vast majority of the mileage of Interstate routes to that effect. The default speed limit for any road where no speed limit is posted is 55 mph. New Mexico has six major freeway facilities, which include three lengthy Interstate routes. Part of US-70 (as a
