As previously stated in this blog, DWI checkpoints are a horribly inefficient way to fight drunk driving in Fairfax County, and Virginia in general. According to a Fairfax County Police News Release there was a checkpoint that took place on Saturday April 9th from midnight until 3 am. The checkpoint required the participation of ten auxiliary officers and 8 police officers. The checkpoint was set up in the westbound lanes of Arlington Boulevard near Annandale Road. Nearly 550 vehicles passed through the checkpoint during that 3 hour period. Of those 550 vehicles only 2 arrests were made for DWI.
