Why use a radar detector or laser jammer in your car?

Radar detectors detect very specific radio transmissions from radar speed measuring equipment, such as speed cameras or police patrol cars.

A good quality radar obtained from radars.com.au can be effective against most of the radar speed measurement technology currently used.

However, police in WA usually only activate their Highway Patrol radar systems when they observe a vehicle which may be speeding.

When that happens, your radar detector will alert you to the police signal so that you can slow down as necessary.

The quicker you slow down (safely), the police radar system needs to recalibrate - giving you more time to slow down. Bear in mind that if the police radar is already running it doesn't need to calibrate itself but you will already have detected it from a distance and can modify your speed if required.

The better radar detectors are also equipped with good to very good laser detection capability.

In WA, there are significant numbers of digital laser speed cameras which replaced the now outdated Multanova wet film radar cameras.

Laser jammers are valuable in alerting the driver to laser speed traps and handheld laser guns. Jammers work by analysing the laser signal received and re transmitting a laser pulse on the same pulse rate and width. This causes the speed camera or radar gun operator to receive a 'non-read' or 'miss-aim' message.

Prevention is better than cure and jamming is widely regarded as an effective way to prevent speeding tickets as it stops the laser speed measuring devices determining your speed.

Jammers should be set to automatically shutdown after a laser threat is detected to prevent an unnecessary discussion with police operators.

The auto shutdown assists in preventing police or camera operators identifying that you have a laser jammer, as they may be prohibited in some areas. Following a pre-set shutdown period, the jammers will automatically re-arm themselves.

In WA laser jammers are not legislated against - but their application may be regarded as interfering with an electronic source or an obstruction offence.

Neither of these constitutes a traffic offence.

Please Note: Extending jamming times while driving is not recommended.
