Drivers in the Netherlands now run the risk of being detected by a smart camera if they break the law by using a mobile phone whilst at the wheel.
After months of testing police rolled out use of the cameras nationwide on Monday.
The infrared cameras monitor both the hands of the driver and the license plate.
If they detect what appears to be an electronic device in the driver's hands, an image is sent on to police so they can verify it.
If the driver is found to be breaking the law by using a device whilst driving, he or she risks a fine of $284 U.S. dollars.
The Netherlands is the first country in Europe to use the smart cameras, following the likes of Australia.
The equipment can operate day and night and in all weather conditions.
The test period proved highly successful. In one day, two cameras registered 400 drivers with a phone in their hand.
