Ecuadorian-American Juan Manuel Correa announced his return to racing on Monday after recovering from the severe leg injuries he suffered in a 2019 Formula Two crash in which Frenchman Anthoine Hubert died.
The 21-year-old said he would drive for the ART Formula Three team.
"Announcing my return to the race tracks is one of the proudest moments in my professional career," Correa said in a statement, promising to honour Hubert's memory.
"My dream is still to reach F1 and this is the first step in my comeback."
Hubert, 22, died after he crashed and his stationary car was then hit by Correa's during the Belgian Grand Prix support race at Spa-Francorchamps.
The FIA said in a subsequent report that Correa hit Hubert's virtually stationary car at 218 kph.
Hubert was the first driver to die at a Formula One race weekend since Brazilian triple champion Ayrton Senna and Austrian Roland Ratzenberger at Imola in Italy in 1994.
Correa suffered 20 fractures to his legs and feet, spending two weeks in an induced coma and wearing a leg brace for more than a year. He underwent 25 bouts of surgery to his legs but avoided amputation.
