McLaren junior Lando Norris secured his fourth European Formula 3 victory with a lights to flag victory in the first race of the weekend at Spa.
Norris, who on Thursday claimed pole for all three races in Belgium, finished 2.807 seconds ahead of Nikita Mazepin after Callum Ilott and Jake Hughes collided on the opening lap.
Ilott was able to get alongside Norris into Les Combes, with Maximilian Gunther and Hughes right behind, but he ran wide over the kerbs and returned to the track into the path of Hughes.
Hughes was sent airborne and retired from the race with broken suspension. Ilott was able to continue, but handed a drive through penalty for causing the collision.
After a safety car allowed marshals to clear the incident, Norris was able to pull away from Gunther, who had inherited second, and left unchallenged for the remainder of the race.
Mazepin passed Gunther around the outside to finish second, his first podium in F3.
Jehan Daruvala took fourth, defending against Joey Mawson late in the race.
A poor qualifying meant Mick Schumacher would start the race 14th, but he spent the race picking his way up through the field to finish sixth.
Ralf Aron had enjoyed a good start, but a problem in the second part of the race saw him drop down the order. He finished 11th, just behind the battle in the second half of the top 10.
Harrison Newey finished seventh after a strong fight up through the field ahead of Ferdinand Habsburg and championship contender Joel Eriksson.
Pedro Piquet rounded out the top 10.
