Update – 3:45 p.m. Monday – A cyclist died after being struck by a truck near the Gaithersburg and North Potomac line, according to county police and fire officials.

Police identified the cyclist as Andrew Gerard Malizio, 60, of Gaithersburg.

Police said a Washington Suburban Sanitary Commission truck traveling west on Darnestown Road was attempting to make a left turn on a green light into the Shops at Potomac Valley shopping center near Washington Avenue when it struck Malizio, who was traveling east on Darnestown Road in the far right travel lane.

Police spokesman Capt. Paul Starks said the green light was not a green arrow. A sign posted at the intersection warns motorists to yield while turning left on green.
