The D.C. council takes up emergency legislation today that would lower the legal blood alcohol rate from for drivers of commercial vehicles from .08 to .04. It would also tighten penalties for any driver convicted of driving under the influence, according to the Associated Press.
D.C. authorities put their breath testing program on hold after realizing that inaccurately calibrated testing equipment had called into question hundreds of convictions.
Officials say they've used other methods to prosecute drivers who may have had too much to drink but establishing a suspect's blood alcohol level is essential for supporting a charge of driving while intoxicated.
Testing is expected to resume next month if the bill passes.
