Former salesman Michael Hershey is in prison for the December 2010 crash in Lancaster County, which killed 48-year-old Jon Jensen and injured his 20-year-old son.
The Legal Intelligencer reports that the car dealership, Imports of Lancaster County, will pay $1.3 million. A mulch supplier whose truck allegedly caused Hershey to swerve will pay another $3 million.
Landyshade Mulch Products and the car dealership deny many of the suit's allegations.
The judge who sentenced Hershey to up to 14 years in prison called the Landisville man "a disaster waiting to happen," given his drinking problem and prior driving violations.
Jensen, of Leola, had been a health administrator at the York County Prison.
