what is the speed limit on i 40 in tennessee
Speed limits in the United States by jurisdiction Tennessee generally posts its rural interstates at 70 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. In 70 mph zones, the default minimum speed limit is 55.[157] Urban interstates are generally posted at 55 to 65 mph, however, portions of Interstates 24, 40, and 65 and S.R. 386 in Davidson County, as well as I-24 in Clarksville are posted at 70 mph. Four-lane divided highways are posted as high as 65 mph but are sometimes 55 mph. These are often hotbeds for speed camera enforcement leading into a municipality.[citation needed] 55 mph speed limits are allowed on two-lane state maintained roads, but some contain 45 and 50 mph limits, even in rural areas, primarily as a result of local policies. In East Tennessee, most mountain roads leading to North Carolina are poorly posted at 45 mph. Furthermore, two-lane roads such as US 321 and S.R. 91 have the same mountain and road width characteristics when leaving Tennessee into North Carolina or Virginia at 55 mph.[citation needed]
Gun laws in Tennessee State supreme court rulings and state attorney general opinions interpret Section 26 to mean regulation cannot and should not interfere with the common lawful uses of firearms, including defense of the home and hunting, but should only be aimed at criminal behavior. Andrews v. State (1870) and Glasscock v. Chattanooga (1928) defined the meaning of regulating arms. "Going armed", carrying any sort of weapon for offense or defense in public, is a crime, except carrying a handgun for defense is allowed with a state-issued permit.
