Roundabout not a ‘vicious circle’
HOLLOMAN AIR FORCE BASE, N.M. -- Two cars drive in the roundabout Jan. 20, 2011, on New Mexico Avenue and Sixth Street. When used correctly, roundabouts essentially eliminate the potential for the most dangerous crashes including right-angle, left-turn, head-on and high-speed collisions.
