Four people were injured in a head-on collision Friday night in Wilson County.
Lebanon police think a Dodge Caravan driving on Highway 231 rear-ended a sport-utility vehicle, then veered into the other lane and hit a Nissan Altima head-on.
The driver of the Altima is in critical condition, according to the Lebanon Democrat.
Police said they think alcohol may have been a factor in the wreck. They believe the Caravan was also involved in a hit-and-run accident before the wreck.
