What is the basic goal of all police work?
To protect the lives and property of the public.
65% of all fatal crashes occur in a speed zone of?
55 MPH or more
NHTSA
National Highway Traffic Safety Administration, the federal agency dedicated to
achieving the highest standards of excellence in motor vehicle and highway safety
Radar is only a ___.
Tool
The overall course goal is?

LESL
Law Enforcement Standards Laboratory
NIST
National Institute of Standards and Technology. NIST is a part of the U.S. Department
of Commerce, and it includes an Information Technology Laboratory (ITL). Formerly the
National Bureau of Standards
What has been the target in almost all successful challenges to RADAR
Human error
RADAR
RAdio Detection And Ranging, a system that uses reflected radio waves to determine
the velocity and location of objects
Brazier v. City of Philadelphia (1906)
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:
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?
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?
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?
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?
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?
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"?
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
"At First Sight/Glance" - based on the first impression; accepted as correct until proved
otherwise
Absolute Speed Limit
the maximum or minimum posted speed at which one may drive under normal
conditions
Does North Carolina have a prima facie speed law?
There is no prima facie speed law in NC
What are the Elements of a Speed Offense?
Driver ID, Location, Speed & Conditions
Elements of a Speed Offense: Driver Identification
Upon observing a violation, the officer should make an immediate visual identification of
the driver. After this, during the "citing" portion, the officer should note more detailed
identifiers (scars, birth marks, hair color, etc.)
Elements of a Speed Offense: Location
Establishing where the defendant's vehicle was being operated at the time of the
infraction.
