According to the California Highway Patrol report, Hart was riding in his 1970 Plymouth Barracuda — a powerful vintage car — with two other people in the wee hours of Sunday on Mulholland Highway in Los Angeles County.
The driver, identified as Jared Black, lost control of the car and it rolled into a gully.
Black, 28, and the third passenger, internet fitness model Rebecca Broxterman, were trapped inside.
“Hart and Black sustained major back injuries as a result of this collision and were transported and treated at nearby hospitals,” Highway Patrol said in the report.
Broxterman, 31, sustained no injuries.
Black, Broxterman’s fiance, was determined not to have been driving under the influence at the time of the crash.
Hart, 40, is a popular comedian and actor, known for roles in “The Secret Life of Pets” and “Jumanji.”
He was asked to host the 2019 Oscars but pulled out when old homophobic tweets of his resurfaced.
The news of the accident has since generated social media buzz with many fans calling for prayers up for Hart.
