Explorer and mountaineer Sir Ranulph Fiennes has been interviewed under caution after his Jaguar was involved in a collision in Greater Manchester.
Sir Ranulph, the oldest Briton to reach the summit of Mount Everest, was taken "dazed and bloodied" from the crash in Stockport in March.
His Jaguar hit a Nissan Micra, leaving the driver with broken ribs and a collapsed lung.
Police said a file will be handed to the Crown Prosecution Service (CPS).
It is believed Sir Ranulph's car swerved into the opposite carriageway of the A6, hitting the Micra then careering into a Ford Focus.
A five-year-old child, who was also travelling in the Micra, suffered minor injuries in the crash.
Double heart bypass
Sir Ranulph, who suffered a minor head injury, had been in the area in order to compete in the 42-mile High Peak Marathon in Derbyshire, as part of a veterans' team called Poles Apart.
The 66-year-old's car mounted a pavement and came to a halt near the front window of an Italian restaurant during the accident shortly before 1400 GMT on the A6 near Dundonald Street.
A woman who drove past just after the accident said Sir Ranulph was sitting "dazed" and bloodied in the passenger seat of his Jaguar.
Sir Ranulph was the first man to visit both the North and South Poles by foot and the first to completely cross Antarctica by foot.
Last May, at the age of 65, he climbed to the top of Everest, the world's highest peak, to raise money for Marie Curie Cancer Care.
Sir Ranulph had a double heart bypass in 2003 and suffered a heart attack two years later as he came agonisingly close to the summit of Everest.
He ran seven marathons on seven continents in seven days in 2003 and climbed the treacherous north face of the Eiger in 2007.
