Online court records don't list an attorney for 49-year-old Miguel Rivera, of Washington, Pa.
He was first charged shortly after 10 a.m. Friday when police say he was legally drunk while driving 142 students to a field trip from Washington Park School.
State police then stopped Rivera about 2:30 a.m. Saturday for drunken driving as he exited Interstate 70, also in Washington.
Police say Rivera's blood-alcohol content was 0.08 percent 30 minutes after he drove the school students. That's the legal limit for drunken driving under normal circumstances, but was four times the state's legal limit of 0.02 percent for a commercial vehicle driver.
