NHTSA Speed Measuring Devices – Questions
With Perfect Solutions
In order to improve the effectiveness of speed enforcement, officers
must: Correct Answer - 1. Observe more speed violations.
2. Apprehend more violators
3. Secure more convictions
True or false: speed measuring devices improve speed enforcement
efforts by providing an accurate measurement of a driver's speed.
Correct Answer - True
True or false: higher speeds make it more likely that a crash will
occur. Correct Answer - True
True or false: higher speeds overwhelm a driver's capability by
limiting his reaction time. Correct Answer - True
True or false: higher speeds increase the time and distance required
to stop a vehicle. Correct Answer - True
True or false: the higher the speed, the more energy present during
a crash. Correct Answer - True
Detection devices reduce speed enforcement effectiveness by giving
drivers advanced warning allowing time to slow down and avoid
getting caught, such as: Correct Answer - Flashing headlights,
cb radio, radar/lidar detectors
True or false: the 2 types of speed laws are the basic speed law and
the absolute speed law. Correct Answer - True
, True or false: the basic speed law states: it is unlawful to drive a
vehicle on public roadways at a speed greater than is reasonable
and prudent under existing conditions. Correct Answer - True
True or false: an absolute speed law states: it is unlawful to drive a
vehicle on public roadways at a speed greater than the specified
limit. Correct Answer - True
Any speed offense has 4 elements. It is essential to establish every
element in order to obtain a conviction. These 4 elements are:
Correct Answer - Driver, vehicle, location, speed
Key factors to consider when choosing a site to conduct speed
enforcement activities: Correct Answer - Need and safety
True or false: doppler principle stated: "when there is relative
motion between 2 objects, 1 which is transmitting an energy wave,
the frequency of the signal as received by the other object changes
due to the relative motion." Correct Answer - True
True or false: if there is relative motion (toward or away) between a
RADAR and an object, the frequency of the reflected signal will be
different than the frequency of the transmitted signal. Correct
Answer - True
The word RADAR is an acronym. It stands for what? Correct
Answer - Radio detecting and ranging
Every radio signal has 2 characteristics that distinguish it from
every other signal. Correct Answer - Wavelength is the
distance from the beginning of the peak to the end of the valley.
Frequency is the number of the waves sent out in the signal during 1
second of time.
