US States With Highest Speed Limits Differs by Vehicle

By Peter Chubb - May 2, 2011

One would have thought that speed limits are the same in all states of the US, but you would be wrong. Some of the highest speed limits in North America are normally in the inland West. Those of you in the Northeast will have some of the lowest speed limits. However, these limits depend on what type of vehicle you drive.

There are different categories for certain vehicles, and the speed limits of these go up in increments of 5MPH; having said that, these limits will also change depending on what time of day you are driving. Normal speed limits average between 60mph to 80mph, again, these change from night to daytime driving.

A new law came in 1995, where states were allowed to set their own speed limits. However, this did not go down well with safety organizations. There seems to be a constant argument that the speed limits set are either too slow or too fast, but are officials ever going to make us all happy?

We do not understand why some limits are the same as they used to be say 20 years ago. Modern cars are nothing like they were two decades ago, they are much safer and can stop much sooner. Some people always say that having a fast car is insane, but you take a Ferrari and a standard family car. Get them both up to 70mph and then get them both to apply their brakes, which one do you think will stop much sooner?

Remember, that these laws are still in place for a reason, so please abide by the speed limits, and stay safe. For a list of all speed limits by state, visit Wikipedia.

    If you consider the fact that there is no speed limit on a lot of the autobahns in Germany, they have a remarkably low death / injury rate, having said that Germans have been taught from an early age to drive responsibly, and have very strict laws governing the maintenance of their vehicles. (If they have even the smallest dent on their vehicle they must have an official letter saying how and when it occured). They would not even consider driving on any road let alone the autobahn with a cell phone attached to their ear, as do a lot of Americans. Therefore I believe that to increase the speed limits to anything above about 80 mph without the relevant education of the American driving population would be dangerous in the extreme. Having said that there are states that do have rediculously low speed limits, Ohio ( slowhio) for instance. If one drives on long, straight, wide roads with very little to while away the time it is all too easy to drift off or at least not consentrate on driving. As a former professional driver (US and Europe) I talk from experience.

    I live in Illinois where at least some highway speeds are too slow at 55, or even 65 in rural areas. And why is there nowhere in the entire state with a 60 mph limit? Most people already drive much faster than the posted limits. A law abiding driver, such as me, can actually be a part of the safety problem. I will gladly drive faster where safely appropriate (many places outside of the urban center) but only if the law permits. Higher speed limits aren't the problem as much as state legislatures that have oppressive laws and police departments that fail to enforce them anyway. Loosed the restrictions, and only those who feel restricted will drive any faster. This will even out highway speeds and possibly make the road safer. I would gladly give up using a phone while driving if I were only permitted to drive faster by law.

    You need to edit the map to include Kansas ( as of July 1 ) & Louisiana ( two weeks ago on I-49 ) as being 75 mph now .
