Spears was driving her 2008 Mercedes on the eastbound Ventura Freeway just east of the 405 freeway about 8:20 p.m. when the mishap occurred, said California Highway Patrol Officer Patrick Kimball.
Spears was in stop-and-go traffic when her car struck a 2006 Nissan in front of her that had stopped. The Nissan then pushed forward into another vehicle. No damage was noted to any of the vehicles.
The CHP took a report and no one was cited.
An after-hours e-mail sent to Spears' publicist was not returned early Sunday.
In 2006, Spears was photographed driving with her son on her lap.
A misdemeanor hit-and-run charge from an August 2007 parking lot crash was dismissed after she paid an undisclosed amount to the car's owner.
In October, she pleaded not guilty to a misdemeanor charge of driving without a valid driver's license and later obtained a temporary California license.
