January Jones was involved in a four-car collision, but was unhurt, police said.
The Mad Men star crashed into three parked cars in Los Angeles Thursday night while being followed by photographers, the Los Angeles Police Department said in a statement to TVGuide.com.
"She walked away from photographers to call 911 and returned to the scene," the statement said. "There was no hit and run. Exchange of information only."
Jones, 32, was not cited or arrested, and there was no evidence of alcohol or drugs.
Jones' rep was not immediately available for comment.
