Police highway patrol hasn't been left behind.

With the demise of Holden and Ford, police now use state-of-the-art BMWs and Chrysler 300C vehicles.

What's inside is impressive:

RADAR: The feature motorists are most familiar with: the radar or speed-catching device. Each highway vehicle is fitted with fixed and hand-held speed check devices (LIDAR and RADAR)."It will pick up cars from 600 metres away, and in some cases it will pick up further," highway patrol chief inspector Mark Cook says.

AUTOMATIC NUMBER PLATE RECOGNITION (ANPR): Police vehicles in NSW are capable of reading up to six number plates in a second thanks to a high-tech number plate reader first introduced in 2013. Three cameras mounted on the car's roof link to a computer running optical recognition software and a database of stolen, unregistered or suspect vehicles, which sounds an alarm every time it finds a match. The data is linked to a laptop computer and mobile data terminal fitted in each vehicle.

VIDEO RECORDING: Highway patrol cars are fitted with an extensive video recording system which films what's going on outside the vehicle's front and rear windows. The video system is integrated into an aftermarket rear-view mirror fitted to each car.

RADIO COMMUNICATION EQUIPMENT: Most law enforcement agencies in Australia, including the police, are increasingly encrypting their communication systems.

RANDOM BREATH TESTING EQUIPMENT: Most motorists are familiar with the "count to 10" process during a roadside breath-test. The device used to record the level of alcohol content in someone's system is called an alcometer, and is a standard fitment in every highway patrol car.

EMERGENCY EQUIPMENT: Police are often first to the scene of big accidents, and as such their vehicles are equipped for most situations. In any ordinary vehicle you'll find traffic cones, A-frame safety triangles, a fire extinguisher and an extensive first-aid kit. There are also emergency lights and sirens, bullet proof vests, batons and torches.

Certainly an impressive array of technology and other tools to help police to do their job.
