Lights, siren, rumbler: Police device shakes up traffic
By MATTHEW KEMENY
HARRISBURG, Pa. — In the midst of an emergency call last month, Lower Allen Twp. Police Officer Matthew Claeys flicked on his cruiser's lights and sirens as he tried to navigate thick traffic on Interstate 83.
Only one or two vehicles heeded the blare, Claeys said. Hoping for a better response, he pressed another button, activating a ground-shaking low-frequency siren known as the Rumbler.
