BRIDGMAN — Michigan State Police troopers responded to a car crash that left a driver and passenger with serious injuries.

Police were called to a car crash at 10:15 p.m. on Saturday along Red Arrow Highway, just south of Linco Road in Lake Township.

Police determined a pickup truck was traveling southbound on Red Arrow Highway in the left lane when it was hit by a 2008 Mercury Grand Marquis.

The Grand Marquis was also traveling southbound on Red Arrow Highway at a high rate of speed and attempted to pass the pickup truck by crossing the center lane into the northbound lanes.

The Grand Marquis clipped the left rear of the pickup truck, crossed both lanes of the northbound lanes, went off the roadway and struck several trees.

Both the driver and passenger of the Grand Marquis were entrapped in their vehicle.

After the driver and passenger were freed, they were transported to Spectrum Health Lakeland Hospital. The driver sustained life-threatening injuries and the passenger suffered serious injuries.

The driver of the Grand Marquis is a 38-year-old woman from Bridgman. The passenger is a 35-year-old man from Benton Harbor.

MSP suspect alcohol was a cause of the crash. Seatbelt use is unknown, but the crash remains under investigation.

The occupants of the pickup truck – who are Stevensville residents – did not sustain any injuries and incurred minor damage to the vehicle.

MSP was assisted by the Lincoln Township Police Department, Baroda-Lake Police Department and the Baroda-Lake Fire Department.
