The incident happened about 11:30 p.m. on Wednesday on the Fairfax County Parkway near Sugarland Drive.
Two officers were on a traffic stop conducting DWI sobriety tests on a driver, police said.
That’s when a 2003 Toyota sedan driven by Alfred Jorge Guillen Escobari struck the rear of the first cruiser, causing it to strike the rear of the second cruiser. The momentum from the initial impact caused the second cruiser to move forward striking both officers.
Both officers were transported to a local hospital with non life-threatening injuries, police said.
The subject driver of the initial traffic stop, John B. St. Pierre, 44, of Vienna, was charged with DWI. Escobari, 23, of Sterling, was also charged with DWI. Neither arrestee required medical attention.
