This is true because it is understood that cars only travel in one direction in any given lane.
The road defines the direction.

sorry i dont know
nothing would had happened.
currently, standard speed limits are: 50 (city) 100 (freeways, two-way-traffic) 130 (highways, one-way-traffic) those limits are always valid, signs would tell you if other speed limits apply. in smaller streets in towns and cities, more and more "30 zones" are installed.
The possessive form for the plural noun highways is highways'.
70 mph
50%
Most interstate highways were designed for the posted speed limits on those interstates.
70
Usually the limits are for axle weight.... the load carried by any single axle is not permitted to exceed a set value (usually 20,000 pounds) and the load carried by any tandem axle is not permitted to exceed 34,000 pounds. The overall weight limit for federal highways is 80,000 pounds for any given vehicle and trailer(s), though bridges and other types of roads (state highways, city streets) may impose lower gross weight limits.

The instantaneous velocity is the limit of the average velocity, as the time interval tends to zero. If you are not familiar with limits, basically you make the time interval very small and calculate the average velocity.
Yes, but they still have speed limits. Its law, the default for highways is 70 "unless otherwiese posted" 55 rural, 25 residential....
In physics, "speed" is how fast you go and "velocity" is how fast you go in a specific direction. On the road, it doesn't matter what direction you are going, only how fast. In common language outside of physics, we usually use "speed" and "velocity" to mean the same thing. But the word "speed" is shorter, so that is usually prefered for use on signs and in writting the laws about how fast you can drive. ************************** speed is really the same as velocity (u asked this at just the right time, i just studdied this in my science! lol). So why they chose to write on the speeding signs "speed" instead of "velocity", i have no idea....But if I think about it, the word "velocity" is more of a scientific name. "speed" is more simple, and to the point...everyone knows what were talking about! AND, if they DID us the word "velocity" over "speed", then you would probably be asking the same question, but reversed- "why are there velocity limits instead of speed limits?" so....do you get where im comming from? but, good question, anyway!!Velocity would not be an accurate measurement unless the highway or street was completely straight because velocity also indicates direction.
Germany has the Autobahn there is no speed limit on the Autobahn. It is Germany's version of a freeway.
