Police in Pacific Grove say the area of First Street and Ocean View Boulevard was a mess Wednesday afternoon.
Several people were injured in the wreck and one of them is in serious condition.
Police say one of the drivers involved in the crash had to be flown out by Calstar to San Jose Regional Hospital, while two others were taken to hospitals on the Central Coast.
The accident happened after police say a driver of a Ford Escort station wagon driving southbound on First Street rear-ended a Ford Taurus, causing chain reaction.
The Ford Escort then drove into a parked car and a stop sign before coming to a complete stop.
Police aren't saying what caused the driver to lose control of their car.
