The 57-year-old was spotted on an airplane runway, travelling on a golf cart with his family before gingerly climbing up the stairs of a jet.
Surveillance video footage of the accident shows Clooney flying over the front of his scooter after hitting the plumber's auto.
On Tuesday, the actor was hit by an oncoming vehicle - the driver failed to give way to Clooney - while on the Italian island of Sardinia.
Clooney did not sustain life-threatening injuries and was discharged from a hospital the same day, leaving with wife Amal.
He was taken to the John Paul II hospital emergency room where he was released a short time later. After complaining of "a slight trauma to the pelvis and bruises to one leg and arm", he was hospitalized, where he underwent an MRI, La Nuova reports.
The Hollywood heartthrob is in Sardinia, an Italian island in the Mediterranean Sea, to film a TV series based on Joseph Heller's novel "Catch-22".
Italian police commander Giovanni Mannoni told CNN that Clooney didn't suffer any serious injuries, including broken bones. TMZ reports that he was traveling at 60 miles per hour and that the impact broke his helmet.
George Clooney and his wife, Amal, prepare to leave Sardinia on July 12 after the actor was released from the hospital following a motorbike accident.
The movie star is recovering at his rented home in Sardinia following the crash near Olbia, Italy on Tuesday, after he was briefly hospitalized, and now the plumber behind the wheel of the auto has opened up about the drama. Amal recently told Vogue that she met George through a mutual friend at his Lake Como home, saying that the progression of their relationship was "the most natural thing in the world". "I'm in shock. It all happened in an instant".
Viglino admits he recognized Clooney as soon as he took his helmet off.
