A little after 5 p.m. yesterday we got word over the newswire of a "Secret Service involved MVA" on the BQE by 39th Street, where a US Secret Service vehicle was hit by a tractor trailer. Today the NY Post has more details, saying an off-duty Secret Service agent was cut off by an 18-wheeler, whose tires flattened the front of his vehicle and caused him "to spin around and slam into a concrete barricade." Another agent had been nearby, and pulled the truck over — but the driver wasn't charged. While the car was totaled, the agent declined medical attention and is reportedly unharmed.
