Mobile phone detectors are to be used by police to find drivers using devices at the wheel.
A new device can detect when motorists are using their mobile phones while driving and warn them to stop reduce the risks of "avoidable" deaths.
Rule breakers will get an automatic fixed penalty notice and penalty points on their license, as well as a fine of £200.
The maximum fine is £1,000 and motorists can be disqualified.
The campaign is being supported by Kate Goldsmith, who lost her daughter Aimee Goldsmith after a lorry driver crashed into the auto she was a passenger in while he was using his mobile phone.
The technology - which can't distinguish between a driver and a passenger using a handheld phone - does not automatically record footage and won't be used to automatically fine drivers at this stage, although future developments could make this possible.
According to MoreBikes, Thames Valley and Hampshire police are working with the traffic signage manufacturers Westcotec to build a device that is installed roadside to monitor both mobile phone signals and passing traffic.
The use of detectors will come into force following 15 April.
Research shows that you are four times more likely to be involved in a crash if you use your phone while driving.
However, it can not tell whether the driver or a passenger is using the phone, so if a phone is being used anywhere in the vehicle and is not attached to a Bluetooth device it will flash regardless.

It can also enable police to identify hotspots where mobile phones are frequently used by motorists.
This new campaign, which was trialled in Norfolk last year, has been supported by bereaved families, such as Kate Goldsmith, who last her 11-year-old daughter, Aimee, due to a lorry driver crashing into the auto she was passenger in while changing music on his phone.
"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".
The technology will not be used as an "enforcement tool", but instead is aimed at motorists to educate them on the potential dangers of driving while distracted.
Ms Goldsmith said she welcomes any technology which can assist in educating people and stop them from using their mobile phones whilst driving.
"Additionally, officers will be carrying out enforcement activity throughout next week".
"My advice would be to turn off your phone whilst driving, put it out of reach, out of view so that more innocent people don't lose their lives".
Norfolk-based Westcotec's managing director Chris Spinks said: "Our system is created to provide intelligence to police officers so that they can carry out enforcement activity in order to reduce the amount of people who are using mobile phones illegally on our roads".
Bluetooth hands-free devices will trigger the system, but the sign won't flash.
TVP announced the use of the technology today.
