A Tuesday afternoon rollover crash in the 800 block of Algonquin Road sent three people to Northwestern Medicine Huntley Hospital, police and fire officials said. Algonquin Police Sgt. Dennis Walker said the crash occurred at about 12:35 p.m. when a vehicle came out of the Algonquin Post Office without the right of way and crashed into a second car, causing it to roll over. Three occupants of the vehicle that flipped were sent to the hospital, according to Algonquin-Lake in the Hills Fire Protection District Battalion Chief John Greene. Walker said eastbound traffic on Algonquin Road was shut down for about 20 minutes and Lake in the Hills police helped manage traffic at the Pyott Road intersection.
