The 46-year-old singer was questioned and released without charge
Singer George Michael was arrested and questioned by police after his Land Rover was in collision with a lorry on the A34 in Berkshire.
The 46-year-old was held on suspicion of driving under the influence of drink or drugs, but released without charge after five hours.
He was taken to Loddon Valley police station near Reading following the incident in the early hours of Friday.
A Thames Valley Police spokeswoman confirmed the singer had been released.
Police were called to the crash, involving a silver Land Rover and a lorry, two miles north of the M4 at about 0001 BST.
"The driver of the Land Rover, a 46-year-old man, was arrested at the scene and taken into police custody," said the spokeswoman.
"He was later released without charge."
In June 2007 the singer was banned from driving for two years after pleading guilty to driving while unfit through drugs.
He was accused of colliding with three parked cars and driving off without notifying the owners.
He was also twice cautioned for possessing cannabis after being found asleep at the wheel of his car on two separate occasions in 2006.
