Instead suspects will be taken to a police facility or hospital for a blood-alcohol test.
State police say they have temporarily suspended use of breath test machines in suspected drunken driving cases because of a judge's concerns about the accuracy of the specific device police were using.
Spokesman Adam Reed told The Philadelphia Inquirer that the decision stems from a Dauphin County judge's decision to throw out several drunken-driving cases after learning that one manufacturer had omitted a state requirement to have a liquid solution tested by independent labs.
Reed said the case is being appealed, but as a precaution police will temporarily refrain from using the devices. Instead, he says, suspects will be taken to a police facility or hospital for a blood-alcohol test.
Reed said the change might actually result in more motorists being charged since blood tests can detect drug intoxication while breath tests cannot.
