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,

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.
Elements of a Speed Offense: Speed
Measurements of speed obtained by RADAR are corroborative only in
establishing the element. It is incumbent upon the officer to produce more
detailed information to show the courts that the defendant's speed was
unreasonable or imprudent
