What advantage does the angular effect provide regarding RADAR speed measurement?

It works to the law enforcement officer's advantage
It works to the motorist's advantage
It causes measurement errors
It increases accuracy in measurements

The correct answer is: It works to the motorist's advantage

The angular effect refers to how the angle at which a RADAR unit is aimed at a moving vehicle can significantly influence the speed reading it provides. When the RADAR signal is transmitted at an angle rather than straight on, it can lead to a discrepancy between the actual speed of the vehicle and the speed measured by the RADAR. This effect can work to the motorist's advantage because when a RADAR is aimed at an angle, the speed measured may be lower than the actual speed of the vehicle, resulting in an underestimation of speed. If a law enforcement officer measures the speed of a vehicle approaching or receding at an angle, this can lead to a reading that does not accurately reflect the true speed. This means that in some scenarios, a driver might be falsely found to be within legal speed limits when they are actually speeding, thus providing an advantage to the motorist.
