The highest posted speed limit in the world is 160 km/h (99 mph), which applies to two motorways in the UAE.
Portions of the Idaho, Montana, Nevada, South Dakota, Texas, Utah, and Wyoming road networks have 80 mph (129 km/h) posted limits. The highest posted speed limit in the country is 85 mph (137 km/h) and can be found only on Texas State Highway 130.
U.S has very bumpy road compare to other places (Even China). So it make sense to make speed limit lower, thus you don't have to replace your car's coilover frequently. In most of the places the left lane is fast lane and the right lane is slow lane. And drivers can choose the lane accordingly.
The Greater London Council and Metropolitan Police asked for a 35 m.p.h. limit in London, but I think that the same arguments also apply.
Thats because there was a time where nationally you could drive no faster than 55 mph. Back during the 70's Oil Crisis, Congress mandated a National 55 MPH speed limit. It has since been repealed. It is the most fuel efficient speed.
New South Wales introduced an absolute speed limit of 100 kilometres per hour (62 mph) in 1979, replacing the limit of 80 kilometres per hour (50 mph) The Northern Territory introduced an absolute speed limit of 110 kilometres per hour (68 mph) in 2007, along with 130 kilometres per hour (81 mph) zones on the
Note that driving less than 5 mph over legal speed limit in Texas state is typically considered acceptable and you should not get a traffic ticket for it. This is a reasonable margin of error and most law enforcement officers will not pull you over for exceeding speed limits by less than 5 miles per hour.
Texas law sets out specific speed limits in various situations if no speed limit signs are posted. For example, section 545.352(b) of the Texas Transportation Code creates a universal speed limit of "30 miles per hour" in urban districts where no specific speed limit signs are posted.
The law sets the maximum at 70 mph, but allows the Texas Transportation Commission to establish a maximum speed limit of 75 mph (80 mph or 85 mph if the highway is designed to accommodate that speed) on the highway system if that speed is determined to be safe and reasonable after a traffic or engineering study.
Some states allow drivers to speed when passing slow vehicles. But, how fast can you go over the speed limit? It varies, but sometimes, when overtaking another car, you are allowed to exceed the speed limit by 10-15 mph. Typically, this applies to two-lane highways where the posted speed limit is 55 mph or higher.
Texas is in the category of speeding laws called presumed laws. A presumed violation gives drivers flexibility. Ticketing is also up to the discretion of the trooper, but as long as you are driving safely, going a few mph over the limit is considered legal.
The limit is 80 on an 89-mile stretch of I-20 between Monahans and the Interstate 10 interchange at the edge of the Jeff Davis Mountains. Same for the 432 miles between Kerrville and El Paso on I-10.
Texas May Let You Pay To Drive 85 MPH
This week, the Texas Department of Transportation approved an 85 mph speed limit for a 40-mile stretch of the SH 130 toll road from Austin to Seguin, which is just north of San Antonio.Speed limits range from 25-45 mph (40-72 km/h).
Limiting speedometers to 85 mph, even though most cars could go much faster, was in response to America's energy crisis. It was an attempt to slow cars down, and in doing so, save gas.
There is no such thing as a motor vehicle speed incapable of endangering life, limb, or property. Speed limits derive from politicians pretending, feigning, concern for our safety! The Supreme Court has struck down as unconstitutional, at least one law when the government's concern on an issue was feigned, faked.
The 55 mph (90 km/h) National Maximum Speed Limit was made permanent when Congress enacted and President Gerald Ford signed into law the Federal-Aid Highway Amendments of 1974 on January 4, 1975.
Originally Answered: Why do most speed limits end in a 5 instead of a 0? It could be an artifact of your location, but three important numbers can explain why: 25, 55 and 65. 55 was the National Speed Limit established by Congress in 1973 that all states had to follow or lose federal highway funding.
First instituted in 1901, speed limits are assigned to increase road safety and reduce the risk of traffic collisions. For a long period, individual states were responsible for determining their own speed limit laws. After oil shortages in the 1970s, Congress established a national maximum speed limit of 55 mph.
The highest posted speed limit in the country is 85 mph (137 km/h) and can be found only on Texas State Highway 130.
55 mph Saves Lives. ON THOSE LONG stretches of open highway in the West, the difference between driving at 55 mph and 65 mph is substantial. Congress imposed the 55-mph limit in 1974 as a fuel-conservation measure, which it is; federal officials estimate it conserves about 9 million gallons of gasoline a day.
The timing of the survey was particularly relevant since Indiana raised the speed limits on its rural interstates from 65 mph to 70 mph on July 1, 2005.
The main reason may simply be that there doesn't need to be a speed limit, and that there never was a compelling reason to implement one. There is no general speed limit, but most stretches of the Autobahn do have individual speed limits. Only a few long-distance stretches between cities truly don't have a speed limit.
The national speed limit simply means the default maximum speed permitted on any given road. You'll be used to seeing signs telling you precisely what the upper speed limit is in miles per hour (mph). But when a national speed limit sign is shown instead, the road defaults to the national speed limit.
As part of his response to the embargo, President Nixon signed a federal law lowering all national highway speed limits to 55 mph. The act was intended to force Americans to drive at speeds deemed more fuel-efficient, thereby curbing the U.S. appetite for foreign oil.
