How does a radar gun work?

Radar handheld devices use radio waves to target a vehicle. As a vehicle passes the radio waves these are reflected back at the radar receiver allowing the handheld radar gun to work out how fast the vehicle is traveling. The speed reading takes no less than 3 seconds for the police officer to acquire. The range of these systems is about 300 yards.


How does a laser gun work?

Laser handheld speed camera guns use a narrow beam of light about 10cm wide. This laser beam bounces from the target vehicle and provides the police officer with a speed reading. The speed is displayed within 0.5 seconds of use meaning speed camera detectors do not have long to warn you that laser is in use. The range of laser guns is about 1 mile.


Marked and unmarked Police cars

Although there are many devices at the Police's disposal to measure and record speed, they can also just use the speedometer fitted in their vehicle. If they suspect a speeding motorist then they can simply follow him or her for a minimum of 2/10 mile or 1056 feet to pull the motorist over and depending on the speed give a warning, issue a Notice of Intended Prosecution (NIP) or for much higher speeds consider court action. This type of speed check is known as a 'follow check' and can be via a marked or unmarked Police cars. However, their speedometer must be certifiably calibrated correctly and regularly tested.


Speeding campaigns

Police officers in different counties across the UK often have a 'Speeding Campaign' of some form particularly during festive times when there are more motorists on the road and when people have busier schedules.

Residents of villages and communities are sometimes given laser guns to check the speed of motorists through their town or village. Though they cannot result in a prosecution the information will be passed on the police and could result in a warning letter being sent.


Points and Penalties

The absolute minimum penalty for being caught speeding on the UK's roads increased 40% in July 2013 from £60 to £100 fine. A minimum of 3 penalty points will also be added to your licence.

However, depending on the road speed limit and your actual recorded speed in the speeding offence a court summons may be generated in place of the Notice of Intended Prosecution (NIP) through the post. For more information click here.
