Speed limits on the USA highway


It is important to know this sped limits. Supose you want to drive from a state to another, and you are used with driving at 75 mph, but in the new state the speed limit is 55. So, this is a good way to avoid speed tickets!

Well you were used by the old laws to drive at 55 mph. Well no more, starting May 2005 1 states had raised speed limits to 70 mph or higher on some portion of their roadway systems. There are often lower speed limits at night and for trucks.

Outside towns speed limits are now almost universally ignored, but most motorists only travel at ten or twenty miles per hour above the limit. In towns, speed limits can be as low as 25mph, and are generally obeyed absolutely. It is very rare to see anyone exceeding a speed limit in a town - those drivers that do are almost always stopped by the police.

In many cases there are progressively slower speed limits as you approach a town (55, 45, 35, 25mph), followed by progressively higher limits as you leave it (25, 35, 45, 55mph).

Effective July 1, 2006, the posted limit on I-85 may be as high as 70 mph.

Read them, learn the one in your state and the one in the state you want to go and you won’t get bustted!

Many drivers will go higher than any posted limits, but also many drivers aren’t really concentrating on the road; some drivers will rapidly alternate lanes to compete with a guy in faster car.

I actually find the speed limits on US highways quite strange (i.e. quite low).

In Europe in most countries the limits are 30 mph in residential areas, 55 mph outside towns (not highways), and 80 mph on highways.

The actual normal speed of the flow of traffic on highways is closer to 90 mph (roughly the limit to which people don’t get fined).

On the German highways (autobahn) in the better segments there is no speed limit, and the cruising speed of better cars is usually 95-100 mph, with some people driving closer to 115.

US highways are extremely good (especially compared to some rural European ones) - 4+ lanes, well-maintained. Most of them could easily support a speed limit of 80+ mph.

Any clue why the limits are so low (especially as the distances are huge compared to Europe, so a 5-10 mph speed difference can make an enormous difference in time to destination)?

Im guessing the urban freeways are used by aircraft..?

Why is there an urban speed of 658 mph in Virginia?
