1158 Speed Measurement Course (FDLE) Questions & Answers Already Passed!!

basic speed law -absolute speed law - Major types of speed regulations include: -interference of radar signals which may be caused by reflective signs on the side of the road that oscillate, electric power lines, transformers, police radios, CBs, and microwave towers -jamming, which is caused by intentional interference with radar signals, either transmitted or reflected -a harmonic, which is a multiple of a radar signal that at times will not allow a radar unit to assign a speed reading - Some factors that may affect radar operation include: -reflected -refracted -absorbed - Radio waves will travel forever unless: -reflective capability -position -speed - Three most common factors that affect a radar units decision process include: -scanning effect -panning effect - Two factors may affect the correct operation of stationary radar: -shape -size -composition - Factors affecting a vehicle's reflectivity include: -steel measuring tape -survey equipment -lasers - Methods of measuring distances:-visual estimation -audio Doppler -target speed display - Elements involved in completing a tracking history in stationary radar include: -visual estimation of target speed -audio Doppler -target display -patrol speed verification ( moving radar only) -target speed discrimination test ( only same direction moving radar) - Elements involved in completing a tracking history in same direction roving radar include: -visual estimation of target speed -Audio Doppler -target speed display -patrol speed verification ( moving radar only) Patrol car speed and the speedometer reading must be within +- 3 miles per hour of each other - Elements involved in completing a radar tracking history include: 1. saves lives 2. prevents injuries 3. reduces crashes - Speed enforcement:
