Today's lesson: If you consumed enough booze to have a blood alcohol level of 0.22—the legal limit is 0.08—you shouldn't be driving! The Post reports, "A public-school teacher whose blood-alcohol level was nearly three times the legal limit struck an off-duty cop's car early yesterday in The Bronx, sources said." Plus, cops "found a small amount of marijuana in her purse. Dana Grippon...was [driving] westbound on East 161st Street in Melrose at 5:15 a.m. when she tried to turn onto Courtland Avenue," and ended up colliding with a car going in the opposite direction. The off-duty cop driving the other car "suffered bruises and minor neck injuries." Grippon was charged with DWI and drug possession.
