The speed limit in Midway Atoll is 15mph (24km/h).[94]. The highest maximum speed limit allowed in NC is 70mph (113km/h) if determined to be "safe and reasonable" by NCDOT engineering studies. Notably, the revised statute does not require a 70-mph speed limit on any road nor make such limit automatic, due to the requirement for traffic and engineering studies. Exceeding the speed limit by more than 15mph (24km/h) with a speed of greater than 55mph (89km/h) or travelling faster than 80mph (129km/h) results in a minimum 30-day license suspension.

[223] This provision allows speed limits of up to 70mph (113km/h) on Interstate highways; multilane, divided, limited-access highways; and express or high-occupancy vehicle lanes if said lanes are physically separated from the regular travel lanes. School zones in Florida usually have 1020mph (1632km/h) limits. The new law strikes the requirement for the Highway Commission to first conduct a traffic study before raising the limit; instead a study will be necessary for the Highway Commission to justify lowering the speed limit.[16]. [71], Interstate Highways in Illinois are usually posted with both minimum and maximum speed limits, except in some urban areas, particularly Chicago. 60 mph on interstate highways such as I-10, I-12, I-20, I-49, and I-220.

When these routes pass through a residential or heavily-trafficked area, the speed limit will usually drop to 25 mph or below. Prior to the imposition of the 50 and 55mph (80 and 89km/h) speed limit in late 1973, Nevada also had a "reasonable and proper" speed Limit (non-numeric) on most of its rural highways, both freeway and others. School zones vary by location, and may be posted with specific hours and/or yellow flashing lights that are active during reduced speed limit hours. Along two-lane roadways, the default speed limit is 50mph (80km/h) during the daytime outside a business or residential district. Speed Limits IC 9-21-5-0.1 Application of certain amendments to chapter Sec. For the most part, these night time reduced speeds are located in wildlife preserves for such endangered species as the Florida panther and the key deer. However, a new law has permitted urban interstates to now be posted as high as 70mph,[55] and some have already reflected this change, such as I-95 through Brunswick, I-85 in Gwinnett County, I-75 in Macon, Valdosta, and Tifton, and I-185 in Columbus .

The minimum speed is defined at 40mph (64km/h) only on Interstate highways. [33][34][35][36][37], If the 85th percentile operating speed as measured by a Traffic and Engineering Survey[38] exceeds the design speed, compulsory legal protection is given to that speedeven if it is unsafe with regard to certain technical aspects such as sight distance.

Minimum speed limits may be posted on a road so that you may not drive slower than indicated. In this state, going 15 mph or more over the speed limit is automatically considered reckless driving. Please note that Hawaii speed limits vary between islands. 70 mph on posted interstates. Made with in Silicon Valley. [233] There are a wide range of speed limits statewide, due to legislated flexibility for WSDOT in balancing the desire for transportation speed against safety considerations for any particular stretch of highway. Michigan uses a formula based on the number of driveways and streets, or on the 85th percentile of free-flowing traffic, and if none those methods are used a 55mph (89km/h) default applies. The speed limit between approximately Broadway Avenue north to the US 71 interchange is increasing from 60 mph to 65 mph. Urban speeds are set, by default, to 30mph (48km/h). 65 mph on a multi-lane divided highway. All other freeways and turnpikes have a maximum of 65mph (105km/h). A viewer asked, Is there A minimum speed limit on Florida highways?. The common limited access freeway speed limit is 65mph. The 50yearold driver (Rudy Stanko) was operating a 1996 Chevrolet Camaro with less than 10,000 miles (16,000km) on the odometer.

This is typically done on very rural state roads (such as SR 471) and US Highways (such as US 98 along most of the state's panhandle). In 1995, the state raised the speed limit on rural stretches of Interstate Highways and the Pennsylvania Turnpike system to 65mph (105km/h), with urban areas having a 55mph (89km/h) limit. Municipalities, on the other hand, can set speed limits on city-controlled roadways, subject to applicable state laws. 45mph speed limits are also not uncommon in more densely populated rural areas. The days of zipping between major Grand Junction exits of Interstate 70 at 75 mph are . As prescribed by Massachusetts law,[87] default speed limits are the following: State highways and other arterials are often posted at 35to 40mph (5664km/h) in urban areas and 45to 50mph (7280km/h) in rural areas. However, some states have prima facie speed limits. "[116] If a speed limit sign indicated km/h, the number was circumscribed and "km/h" was written below.

The maximum speed limit in Nebraska is 75mph on rural Interstate highways. By the end of 2016, UDOT raised speed limits to 80mph on additional sections of I-15 and I-70.[221]. It is a common misconception that undivided highways may only be posted up to 55mph (89km/h) in Tennessee. The maximum speed limit on other rural highways is 65mph (105km/h). Residential speed limits in Louisiana may also vary, as posted. A successful prima facie defense is rare. Initial studies found that lower speed limits could provide roughly 1.5% of the emissions reductions required for Clean Air Act compliance. Speed limits for all roads within Connecticutincluding local streetsare established by the State Traffic Commission, an agency composed of members of the Department of Motor Vehicles (CTDMV), the Department of Emergency Services and Public Protection (DESPP), and the Department of Transportation (CONNDOT). The highest posted speed limit in the country is 85mph (137km/h) and can be found only on Texas State Highway 130, a toll road that bypasses the Austin metropolitan area for long-distance traffic. POSTED SPEED LIMIT Posted speed limits (sometimes called regulatory speed limits) are those that are sign-posted along the road and are enforceable by law. [217], "Motor trucks and buses" are limited to 40mph (64km/h) on St. Croix's main divided highway, 30mph (48km/h) on other highways outside of towns, and 15mph (24km/h) within towns.
