**In Nevada the maximum speed limits are posted at 65-75 mph (105–121 km/h) on rural freeway, 65–75 mph (105–121 km/h) on other rural divided highways, 55–70 mph (89–113 km/h) on primary two-lane roads, and 65 mph (105 km/h) on urban freeways.**

For example, I-15 is posted 70 mph (113 km/h) south of Las Vegas to match California’s 70 mph (113 km/h) posted limit, US 95 north of Las Vegas is 70 mph (113 km/h), US 95 from south of US 93 near Boulder City south to Nevada Highway 163 is 75 mph (121 km/h), I-80 from Reno to Utah, varies 65–75 mph (105-121 km/h). Most rural sections are posted at 75 mph (121 km/h). Mountainous sections and those laid through narrow valleys are usually 70 mph (113 km/h). West of Reno, I-80 is posted at 65 mph (105 km/h) as it quickly transitions from suburban Reno to crossing the Sierras into California, where the limit is also 65 mph (105 km/h). The speed limit on US 50 Lake Tahoe to Ely and Utah is 65 mph (105 km/h), on I-580 Exit 44 to just south of Exit 56 is 70 mph (113 km/h); then, it’s 65 mph (105 km/h) and on US 95 through downtown Las Vegas is 65 mph (105 km/h).

The speed limit on certain two-lane highways is 70 mph (113 km/h) including US 95 to the Oregon border (where the speed limit drops to 65 mph / 105 km/h for trucks) and on certain sections of US 6 and 50 as they cross the Nevada desert.

Speed limits are 15 to 25 mph (24 to 40 km/h) in school zones and 25 to 30 mph (40 to 48 km/h) in residential districts.
