Howard County police said a motorcycle traveling on Route 32 collided with a vehicle at Old Frederick Road Saturday.
Around 7:20 p.m. 58-year-old Kenneth Reid Stalcup was driving a 2003 Yamaha XV1600 in the southbound lane collided into a Honda CR-V, police said.
Forty-eight-year-old Sandy Pohyang Kim, driver of the Honda, was crossing Route 32 on Old Frederick Road when her vehicle was struck by the Yamaha, according to a preliminary investigation. Investigators said they believe the Honda had a green light.
