The two other buses were involved in a separate crash further down in traffic near Kenilworth Avenue.

Thirteen passengers complained of neck and back pain after the collision; Eight on the first bus and five on the second. No injuries were reported on the third bus. All injuries were considered minor.

Prince George's County fire department spokesman Mark Brady says several pieces of equipment were required to transport injured passengers to hospitals.
The crash occurred shortly after 10 a.m. on Wednesday morning in Greenbelt.
