Yes, it may be excused under certain circumstances - all of which would be emergencies. One possible exception (in many states) is when passing another car on a two lane road where you can exceed the limit up to 10 mph if reduced when back in your lane.
Anything above the speed limit is technically illegal, however, many police officers will let it slide. Some police forces allow it. They may allow the speed limit + a few percent of it
You may exceed the posted speed limit FOR A FEW MOMENTS while actually in the act of passing, however you must immediately return to the speed limit after the pass is safely completed.
Whatever the posted speed limit is.
If the runway is in the city, the speed limit is 20 miles per hour unless otherwise posted.
When it is flashing the speed posted is the limit
Do not speed. Most police officers will not bother ticketing someone doing five or less miles over the speed limit.
Varies by jurisdiction. Ultimately, it will be whatever speed limit is posted.
the posted speed limit

There is no such thing as a "residential highway."If you are speaking of a residential street - the usual speed in urban and suburban areas, unless otherwise posted, is 25 miles per hour.
55 on the highway, and 30 in the city.
Whatever the posted speed limit is.
No. The posted speed limit of 55 miles an hour means you can drive a maximum of 55 miles an hour when it is safe to drive at that speed. Only an idiot would drive at that speed in fog and high wind.
This question makes no sense, what do you mean? the speed of the car does not dictate the posted speed limit.
true
They are as high as 65. In North Dakota, the speed limit is 65 mph on two-lane highways if posted for that speed.
Scooters are allowed on the highway as long as they can travel at the posted speed limit.
The maximum speed limit in Florida is 55 mph, except where otherwise posted. Speed limits are 70 mph on some rural interstate highways.
Ummm...pretty sure it depends on the speed limit of the highway!
