NC RADAR-LIDAR
What is the basic principle of RADAR? - answer The radio frequency energy is
generated by a transmitter, the antenna forms the energy into a beam and the energy is
transmitted into space. This energy will travel indefinitely unless absorbed, refracted or
reflected. When the energy or signal strikes an object, a small amount is reflected back
to the antenna. From the antenna, it is sent to the receiver where it is recognized or
"detected".
What does the Antenna do? - answer Shapes, Forms, Transmits and Receives
Microwave Energy.
How much training does Basic RADAR operator and RADAR Re-cert require? - answer
Basic - 30 Hours, Re-cert - 6 hours.
What minimum score is required on the state exam for the basic RADAR and Re-cert? -
answer70% for basic 75% for re-cert exams.
How long do you have to complete the road test and score 100% on the 18 basic
configuration clocks. - answer2 hours, 42 mph or less on clocks
If your time expires, can you take your retest? - answerNo
Are you allowed a retest on a block during the driving test? - answerYes
In Basic Radar can you retest on the skills setup/config/road test or written exam? Can
you retest on Re-certs? - answer1 retest on either the skills setup/config/road test or
written exam, not both. No retest on re-certs.
Speed affects what three elements? - answerOperation, Vehicle, and Roadway
What are the two types of speed laws? - answerAbsolute (posted speed limit) and Basic
(Reasonable and Prudent under existing conditions)
What is the General Statute for Speeding? - answer20-141
What is the General Statute for C&R driving - answer20-140 A/B
What national crisis happened causing Congress to impose a 55 mph speed limit nation
wide? - answerOil Embargo occurred in 1973
When was the national speed limit lowered and when was it changed? -
answerLowered to 55 mph in 1974 and raised to 65 in 1987
, When the speed limit was increased to 60 mph what % did the fatals rise by and how
many deaths was that? - answer9%, 3500 deaths
What does RADAR stand for? - answerRadio Detection and Ranging
What is Judicial notice? - answerCommon knowledge and familiar to all reasonably well
informed people
How often must the RADAR unit be tested and calibrated? - answerCalibrated every 12
months and tested at least one time daily. Unit should be tested at beginning of shift
and after each enforcement action (Tuning Forks)
Tuning Forks test measurement can be no greater than? - answer+ or - 1 MPH of
stamped value
N.C.G.S. 8-50.2 is what? - answerRadar Liability Act of 1982
How many parts does the RADAR liability act have? - answer4 - Training Certificate,
Procedures, Instrument on approved list, Calibrated tested unit.
What was the earliest mechanical device for measuring speed? - answerStop Watch
When the RADAR is calibrated by a technician , what must the tech possess? -
answerA General Radiotelephone License from the FCC or Possess a Certified
Electronics Technician certificate issued by the FCC
Why is a public safety radio license required to use the RADAR? - answerThe Radar is
considered a push button device by the FCC.
What does Prima Facie mean? - answerat first sight/glance
Radio Energy Travels how fast? - answerSpeed of light - 186,000 miles per second
Waves consist of what? - answera peak and a valley
Radio Waves have three distinguishable characteristics - answerSignal Speed, Wave
length and frequency
Where are Wave lengths measured to and from and measure approximately how long?
- answerFrom the beginning of the peak to the end of the valley and measure
approximately 3cm or 1-1/5 inches.
A RADAR has a frequency of more than what? - answer10,000,000,000 waves per
second (10 billion)
