what are the maximum and minimum speeds on interstates in mississippi
Speed limits in the United States by jurisdiction Mississippi has a minimum speed of 30 mph on four-lane U.S. highways when no hazard exists. Strangely, there is no law for the minimum speed of the state's growing number of four-lane state highways. The minimum is 40 mph on Interstate Highways and on four-lane U.S. designated highways that have a 70 mph speed limit.[88] In 2004, Mississippi posted minimum speed limits (40 mph) on all rural Interstates, but this minimum speed limit was already state law before then.
New Jersey Turnpike The default speed limit is 65 mph (105 km/h) between the southern terminus and milepost 97, and 55 mph (89 km/h) from there to the northern terminus. The Newark Bay Extension carries a 50 mph (80 km/h) limit. The turnpike has variable speed limit signs allowing for the limit to be temporarily lowered during unusual road conditions.[22]
