(ITL). Formerly the National Bureau of Standards
What has been the target in almost all successful challenges to RADAR - Answers -

Brazier v. City of Philadelphia (1906) - Answers - Affirmed a conviction under a city
ordinance for speeding over 7 mph - "It is only necessary to resort to the most cursory
observation to find the evidence that many drivers of automobiles in their desire to put
their novel and rapid machines to a test of their capacity, drive such vehicles through
the streets with a reckless disregard of the rights of others."
Increased speeds affect the 3 Elements of Driving, which are: - Answers - 1. The
Operator - increased speeds serve to tax the basic capabilities of the driver, such as his
reaction time (the time required to respond to a situation) as well as amplifying any
existing physical deficiencies, such as vision
, 2. The Vehicle - increased speeds tax the automobile equipment, the brakes, steering,
etc.
3. The Road Surface - increased speeds amplify the potential hazards of any
deficiencies in the road surface (potholes, construction, etc.) or situational conditions
resulting from weather, ice, snow, or rain
At a speed of 20 MPH, what is the stopping distance? - Answers - Reaction Time
Distance = 22ft
Braking distance = 20 ft.
Stopping distance = 22ft + 20ft = 42 ft
At a speed of 40 MPH, what is the stopping distance? - Answers - Reaction Time
Distance = 44 ft
Braking distance = 81 ft
Stopping distance = 44ft + 81 ft = 125 ft
*Note* the braking distance is 4 times that of 20 mph
At a speed of 80 MPH, what is the stopping distance? - Answers - Reaction Time
distance = 88ft
Braking distance = 410 ft
Stopping distance = 88 ft + 410 ft = 498 ft
*Note* the braking distance is more than 16 times that of 20 mph
According to Joseph Nathan's "Famous First" the very first traffic law in America was? -
Answers - Passed on June 12, 1652 by New Amsterdam (now New York). It prohibited
the riding of horses at a gallop, or driving a horse-drawn vehicle at a galloping speed,
within the city limits.
The first automobile speed regulation was? - Answers - enacted in 1901 by Hartford,
Connecticut. It limited automobile speeds to 12 mph in the country and 8 mph within the
city limits
What is known as the "Basic Speed Law"? - Answers - No person should drive a vehicle
on a highway at a speed greater than is reasonable and prudent under the existing
conditions. Ours is N.C.G.S. 20-141(A)
Prima Facie and Absolute Speed Limit
Prima Facie - Answers - "At First Sight/Glance" - based on the first impression;
accepted as correct until proved otherwise
Absolute Speed Limit - Answers - the maximum or minimum posted speed at which one
may drive under normal conditions
Does North Carolina have a prima facie speed law? - Answers - There is no prima facie
speed law in NC
