Just like a breathalyzer tests a driver’s breath to gauge the level of alcohol in his system, a textalyzer will gauge whether or not a driver has been tapping or swiping their phone.
After an accident, law enforcement can plug the driver’s phone into the device to check if was being used prior to the accident. Many legal experts believe a textalyzer is an invasion of privacy as well as an imperfect solution in determining who was actually doing the texting or if speech-to-text was enabled.
While the textalyzer will likely end up in the Supreme Court for individual drivers, truck drivers are held to a higher standard and such a device may very well become part of the accident review process in incidents involving commercial truck drivers.
It is still under review, and we will keep you posted.
