According to the Associated Press, Col. Tom Mars says he wants the legal limit for truck drivers and other commercial drivers reduced from 0.04 blood-alcohol level to 0.02 percent.
Mars told the AP that the state should be as tough on commercial drivers as it is on minors who drink and drive. Police can charge drivers under 21 with driving under the influence if they have a blood-alcohol content of 0.02 percent.
"The state won't tolerate a 20-year-old college student with 0.02 driving, but it will tolerate a 0.02 from a 40-year-old truck driver in an 80,000-pound rig," Mars told the AP. "That doesn't make a lot of sense to me."
State law also prevents commercial drivers from drinking alcohol in the four hours before going on duty.
The limit for other motorists to be arrested on a DWI charge is 0.10 percent, but state lawmakers have discussed lowering the limit since Congress passed legislation to withhold some federal highway funds from states that fail to drop their drunken driving standard to 0.08 percent, AP reported.
