Late singer Angie Stone’s two children are suing the drivers, a trucking company and a truck manufacturer involved in the devastating car crash in Alabama that killed Stone in March.

Stone’s kids, Diamond Stone and Michael D’Angelo Archer, filed the lawsuit Tuesday in Gwinnett County in Atlanta, according to documents obtained by WSB-TV.

The lawsuit claims that Angie actually survived the initial car crash, when the driver of the Mercedes-Benz Sprinter van she was riding in with her entourage and bandmates lost control of the vehicle and it flipped over.

According to the lawsuit, passersby helped pull five of the nine passengers out of the van. Angie, however, was still trying to exit the vehicle when a tractor-trailer carrying a load of sugar slammed into the van. Angie was ejected from van on impact and got pinned under it, where she died, the lawsuit claims.

The lawsuit also claims that the driver of the tractor-trailer “was not paying proper attention to the roadway ahead of him” and the collision mitigation system in the vehicle failed.

Angie was headed home after a performance in Mobile, Ala., at the time of the crash. The documents state that she “consciously suffered” as she remained trapped underneath the van and ultimately died.

She was 63 years old.

Trucking company CSRT and truck manufacturer Daimler Truck North America didn’t immediately respond to Page Six’s request for comment.

The “More Than a Woman” singer shared her daughter, Diamond, with her ex-husband, Rodney Stone. She shared her son, Michael, with D’Angelo.

Diamond confirmed the heartbreaking news of her mother’s death in a Facebook post shortly after the crash.

“My mommy is gone,” she wrote alongside several crying emojis.

The Grammy-nominated singer shot to fame in 1979 when she joined the all-women trio, The Sequence, with Cheryl Cook and Gwendolyn Chisolm.

She eventually started her own solo career in the ’90s and released her 1999 album, “Black Diamond.”
