The program follows police involved in attending major road accidents, high-speed police chases, confronting drunk drivers as well as issuing lesser penalty notices to drivers for a variety of traffic offences.[2]
Each episode follows the progress of a select few incidents involving various officers, from the first encounter by the officers through to the officers leaving the scene, with the exception that occasionally the officers will escort a driver back to a police station for the purpose of a breath or blood sample. Fines, court convictions and demerit points issued in relation to each incident are shown in a voiced-over addendum at the end.
