Probably determined by the method used for enforcement. It refers to the speed you are going when the radar gun pings you (instantaneous speed) or the time it takes to cover a predetermined distance from an aircraft (average speed).
The above refers to enforcement, as indicated. And it is correct. As regards enforcement. The to the question is that the speed limit sign refers to the maximum instantaneous speed at any point in your travels on a roadway that is so marked.

TaigaThe speed limit sign typically refers to the maximum allowable instantaneous speed that a vehicle can travel at any given moment on that road. It is not an average speed limit. Drivers are expected to adhere to this maximum speed limit at all times while driving on that road.

Does light speed accelerate or is it instantaneous velocity?
Instantaneous.
How is speed calculate?
Average speed is calculated by dividing the total distance covered divided by the time taken. Instantaneous speed is calculated as the derivative of displacement with respect to time.
What does the slope of the instantaneous speed-vs-time graph represented?
The slope of the instantaneous speed-vs-time graph represents the acceleration of the object. A positive slope indicates the object is accelerating in the positive direction, while a negative slope indicates acceleration in the negative direction. The steeper the slope, the greater the magnitude of the acceleration.
Is the average speed equal to the magnitude of the average velocity justify your answer?
No, the average speed and magnitude of average velocity are not always equal. Average speed is the total distance traveled divided by the total time taken, while average velocity is the displacement divided by time, including direction. If an object changes direction during the motion, then the average speed and average velocity will differ.
What is speed limit on snow covered roads?
The speed limit doesn't change, but you are expected to make a reasonable adjustment to your speed to compensate for the conditions. So basically, as fast as you can go at or below the speed limit without getting into a wreck.
