Brazier v. City of Philadelphia (1906) - CORRECT ANSWER 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

Increased speeds affect the 3 Elements of Driving, which are: - CORRECT
ANSWER 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? - CORRECT
ANSWER 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? - CORRECT
ANSWER 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? - CORRECT
ANSWER 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? -
CORRECT ANSWER 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? - CORRECT ANSWER 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"? - CORRECT ANSWER 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 - CORRECT ANSWER "At First Sight/Glance" - based on the first
impression; accepted as correct until proved otherwise
Absolute Speed Limit - CORRECT ANSWER the maximum or minimum posted speed
at which one may drive under normal conditions
Does North Carolina have a prima facie speed law? - CORRECT ANSWER There is
no prima facie speed law in NC
