Beginning Jan. 1, cameras will take photos of the user each time the machine is activated to verify the driver is the one who took the test, according to a Washington State Patrol news release.
Ignition interlocks are required on the vehicles of those accused or convicted of impaired driving and have been issued Ignition Interlock Licenses.
The machine requires the driver to provide a breath sample before allowing the car to start.
"We've had cases where impaired drivers asked passengers, friends or even children to take the test for them," said State Patrol Lt. Rob Sharpe. "We've even heard stories of people trying to use portable air compressors to take the test."
The company which leases the interlocks keeps tracks of those who fail or try to tamper with the machine and contacts the State Patrol.
"We do make personal visits to drivers if we have evidence they have tried to foll the machine," Sharpe said. "Having a picture will be the best possible evidence that someone was trying to cheat."
