On I-80 in Evanston and Cheyenne, I-25 in Cheyenne and Casper, and I-90 in Buffalo, the speed limit is 65 mph. In February 2014, the state Assembly passed a bill that would raise the speed limit from 75 to 80 mph on certain freeway segments that would meet safety standards. The bill passed the Senate on Feb 25 and raised the speed limit on certain freeway sections to 80 mph on

Freeways and expressways in urban areas are posted at 65 mph. The speed limit in rural areas of Nebraska is 65 mph unless otherwise posted, although rural divided highways and Super two highways are posted at 70 mph.

School zones in Ohio normally have a 20 mph speed limit, regardless of the road's normal speed limit, in effect during school hours. In Oklahoma, the maximum posted speed limit is 75 miles per hour on turnpikes and 70 mph on all other freeways. Most other rural highways, divided or undivided, have a 65 mph speed limit (although some rural divided highways have a 70 mph limit). The minimum speed limit on almost all Interstate

Furthermore, the speed limit drops from 65 mph on rural highways to 40 mph at the approach to the Canada–US border on Interstates 89 and 91, at Highgate and Derby Line, respectively. In school zones, the speed limit can range from 20 mph to 25 mph, depending on local authority. The minimum speed is defined at 40 mph only on Interstate highways. That includes where the limit is posted at 55 and 65 mph. However, as old signs are being replaced, the "40 MINIMUM" is being phased out, keeping only "SPEED LIMIT

In the urban areas of Sioux Falls and Rapid city, a 65 mph speed limit is posted on Interstates 90 and 29. In March 2015, SD State Legislature has passed the bill to raise the speed limit on Interstate 29 and Interstate 90 to 80 mph. It was signed into law and took effect in April 2015. While the 80 MPH speed limit was initially signed on all rural freeways in the state, the Interstate 90 stretch from Rapid City

Prior to the 1974 federal speed limit law, all Interstates and the Turnpike had a 65 mph (105 km/h) speed limit on rural stretches and 60 mph (97 km/h) speed limit in urban areas. In 1995, the state raised the speed limit on rural stretches of Interstate Highways and the Pennsylvania Turnpike system to 65 mph (105 km/h), with urban areas having a 55 mph (89 km/h) limit. In 1997, PennDOT raised the speed limit to some rural non-Interstate Highway bypasses to 65 mph (105 km/h). In 2005, with the

The default speed limit, posted as the "State Speed Limit", is 55 mph, which is in effect unless otherwise posted or in the absence of speed limit signs.

At one time, these minimum speeds required signage, but these limits have since been codified in state law; signs indicating these minimum speeds still exist, but now simply serve as a reminder. Urban freeways with speed limits of 50 mph typically do not have minimum speed limits, such as on I-375 in St. Petersburg. Additionally, the new Gandy Freeway in St Petersburg has a speed limit as low as . Florida also does not impose lower truck speed

Although the speed limit can be raised to 70 mph based on engineering studies under current law, ODOT has not identified any freeway sections that it believes should be raised beyond the 65 mph limit.

As of October 31, 2017, the speed limit law is being broken into four categories: rural interstates, Urban Interstates, rural divided unlimited access highways, and two lane highways. There are studies being made to increase rural interstate speed limits to 75 mph (121 km/h), urban interstate speed limits to a uniform 65 mph (105 km/h) speed limit, rural divided unlimited access highways to 65 mph (105 km/h) unless the DOT

Urban Interstate speed limits generally vary from 55 mph to 65 mph. Sections of I-64 and I-68 have lower truck speed limits because of steep grades; otherwise, West Virginia does not post separate truck speed limits. The West Virginia Turnpike between Chelyan and Mahan has a 60 mph speed limit because of sharp curves.

wartime, New Mexico had no default numeric speed limit until the early 1950s. Prior to the national 55 mph limit in 1974, the speed limit on rural Interstates was 75 miles per hour during the day and 70 mph at night. 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.

These include all of the state's two-digit Interstates except Interstate 55 and Interstate 26. The only auxiliary interstates in Tennessee with a 70 mph speed limit are Interstate 155 and Interstate 840. 70 mph speed limits are allowed on all other controlled access highways, and are found on controlled-access portions of U.S. 51 and S.R. 22, 111, 386, and 396.

However, an attempt to raise the speed limit to 70 on two lane highways such as Wyoming 120 and US 14 was turned down that same month, but this same provision became law in February 2015. On February 1, 2016, the speed limit on WY 120 (two lane highway) from the Chief Joseph Highway to the Montana border increased to 70 mph.

It is a divided at-grade expressway with a speed limit due to the frequency of signals. There are five traffic signals along I-180. This is nowhere near Interstate standards, but it received federal funding under the Interstate Highway program. I-180 is cosigned with Business Loop Interstate 25, U.S. Highway 85 and U.S. Highway 87 Business, making it the only concurrency of an Interstate, a Business Loop Interstate, a U.S. route and a Business U.S. route.

In the late 1960s, heavily traveled portions of the New Jersey Turnpike began using variable speed limit signs, in combination with variable message signs. Officials can adjust the speed limit according to weather, traffic conditions, and construction. More typically, variable speed limits are used on remote stretches of highway in the United States in areas with extreme changes in driving conditions. For example, variable limits were introduced in October 2010 on a stretch of Interstate 80 in Wyoming, replacing the winter season speed reduction from

These particular stretches of I-25 were originally built as relocations of US-85, whose design and construction predate the interstate highway era. As such, these stretches do not meet modern interstate highway standards, and have closely spaced interchanges, sharp curves, and/or limited sight distances. By statute,

Days before the law was to go into effect, however, it was put on hold in order to allow a more thorough review of the effects of a raised speed limit.

In the densest urban districts a statutory 25 mph limit is effective when adequate signage is used, as are 35 mph limits in areas of light development. The same applies to 45 mph limits on highways designated as "rustic" roads. However, "an alleged failure to post [such a speed limit sign] is not a defense to a prosecution" in the case of such statutory limits. Wyoming's highest speed limit is 80 mph, found on its Interstate highways, and 70 mph on its four lane divided highways.
