The family of Shenandoah Clark sued Toyota alleging the truck was defective. Clark died in 2011.
A Hinds County jury in 2009 ruled for Toyota. The state Court of Appeals upheld the verdict last year.
The Supreme Court on Thursday agreed to hear an appeal from Clark's family, which wants the lawsuit to go to trial.
Toyota, according to court documents, argued Clark's negligence caused the accident not any defect in the truck.
