The posted speed limit.
There are many factors that you should consider when selecting the speed of your vehicle. Some of the important factors include stability, consumption of the vehicle as well as the main purpose of the vehicle.
Yes it is acceptable to momentarily accelerate over the speed limit tp get around a vehicle moving slower than the posted speed limit but you must return to the speed limit after passing.
It is never legal to go above the posted limit. Even when passing a vehicle. That's called an absolute speed law. Only emergency vehicles responding to an emergency may exceed the limit and then only when "reasonable".
In general the answer is, technically, no, you may not. However if you are passing a slower moving vehicle it would be considered 'lawful' to exceed the limit to pass the slower moving vehicle and then immediately return to the posted limit once it was passed.
The Law:The speed limit is the speed LIMIT.Reality: It very often is not possible to pass safely with out exceeding the limit, the book says if you have to speed you should not pass.The fact that we often do exceed the limit to safely pass, and the Police look the other way (if it is by a minor amount, and the pass is made safely) is immaterial. They can ticket you for exceeding the posted limit at any time.
If the runway is in the city, the speed limit is 20 miles per hour unless otherwise posted.
as long as you do not exceed the posted speed limit. the posted speed limit is the maximun speed which a vehicle may be operated. it does not have a built in tolerance for five or ten miles per hour. it is the LIMIT, you could theorecially get a citation for even ONE mile in speed over the limit.
No nobody should be driving below posted limit and it will speed them up as long as u back off slightly after they've achieved posted limit driving below or to high above posted limit causes more accidents then trying to make someone go the speed limit
