Mobile phone detectors are to be used by police to find drivers using devices at the wheel.
Hampshire and Thames Valley police forces are the first to roll out use of the device which also allows officers to identify hotspots where mobile phones are frequently used by motorists.
The system, developed by Westcotec, is able to detect when 2G, 3G or 4G signals are being sent out, specifically when a phone is being used, using a directional antenna.
If the device determines a signal is being sent by a motorist, it will send a warning that flashes on their device's screen.
Highways England is splashing out £10,000 on two signs that will warn drivers if the kit detects a phone call in progress but with no Bluetooth set being used at the same time. The roadside gadget isn't meant to serve an enforcement purpose-it's only supposed to raise awareness, and telling people they shouldn't be texting and driving isn't a bad idea, even if they aren't driving at the time they're told that.More news: #RewriteTheRules with the Huawei P30 series
Rule breakers will get an automatic fixed penalty notice and penalty points on their license, as well as a fine of £200.
If people are using a Bluetooth hands-free device, the detector will recognise this and not flash.
The new campaign has been welcomed by Kate Goldsmith, whose daughter Aimee was tragically killed when a lorry driver crashed into a vehicle she was traveling in while using his phone to change music.
"My daughter's death was completely avoidable".
PC Liz Johnson, a roads safety officer for the Joint Operations Roads Policing Unit, said: "Research shows us that you are four times more likely to crash if you are using a mobile phone whilst driving, reaction times are around 50% slower than a driver not using a mobile phone".More news: Redmi Pro 2 leaked: Snapdragon 855 and cut-hole display
Norfolk County Council was the first to trial the road signs a year ago, but this is the first time that the police has chose to deploy the technology.
The mother of 11-year-old girl killed on the A34 in 2016 is backing the use of the new technology.
"In the Thames Valley since 2014 there have been 83 people killed or seriously injured as a result of drivers using their mobile phones and 40 have been killed or seriously injured in Hampshire". We will be utilising a bus in order to travel around locations in the Thames Valley and Hampshire to spot motorists breaking the law and using mobile phones.
Ms Goldsmith said: "I am supporting this campaign and welcome any technology which can assist in educating people and stop them from using their mobile phones whilst driving".
We wouldn't be surprised, given the goal is to make using your phone while driving "as socially unacceptable as drink-driving".More news: Disney Streaming Service Reveals Full Lineup of Marvel Series
