WebA primary traffic offense is a violation for which a police officer can stop a driver and issue a citation. With a secondary offense, an officer can issue a citation only if there's some other valid reason to stop the driver. In other words, the basis for stopping the motorist can't be just the violation of a secondary offense. WebDescription.

WebNov 2, 2007 · Radar systems detect the presence, direction or range of aircraft, ships or other, usually moving objects. This is achieved by sending pulses of high frequency electromagnetic fields (EMF). Invented some 60 years ago, radar systems have been widely used for navigation, aviation, national defence and weather forecasting. A Primary radar (PSR Primary Surveillance Radar) is a conventional radar sensor that illuminates a large portion of space with an electromagnetic wave and receives back the reflected waves from targets within that space. The term thus refers to a radar system used to detect and localize potentially non-cooperative targets. It is specific to the field of air traffic control where it is opposed to the secondary radar which receives additional information from the target's transpond…
