NC RADAR/LIDAR QUESTIONS AND ANSWERS
What is the basic principle of RADAR? - Answers - 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? - Answers - Shapes, Forms, Transmits and Receives
Microwave Energy.
How much training does Basic RADAR operator and RADAR Re-cert require? -
Answers - Basic - 30 Hours, Re-cert - 6 hours.
What minimum score is required on the state exam for the basic RADAR and Re-cert? -
Answers - 70% 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. - Answers - 2 hours, 42 mph or less on clocks
If your time expires, can you take your retest? - Answers - No
Are you allowed a retest on a block during the driving test? - Answers - Yes
In Basic Radar can you retest on the skills setup/config/road test or written exam? Can
you retest on Re-certs? - Answers - 1 retest on either the skills setup/config/road test or
written exam, not both. No retest on re-certs.
Speed affects what three elements? - Answers - Operation, Vehicle, and Roadway

Basic (Reasonable and Prudent under existing conditions)
What is the General Statute for Speeding? - Answers - 20-141
What is the General Statute for C&R driving - Answers - 20-140 A/B
What national crisis happened causing Congress to impose a 55 mph speed limit nation
wide? - Answers - Oil Embargo occurred in 1973
When was the national speed limit lowered and when was it changed? - Answers -
