Police received multiple 911 calls about the crash at 2:48 this afternoon, officials said.
A woman driving a Subaru Legacy wagon was pulling away from the traffic light at Canyon headed northbound on Folsom when she suddenly grazed several other vehicles, Boulder police Sgt. Laurie Wegscheider said.
The driver suffered a broken bone in her foot or ankle and was transported to Boulder Community Health.
No one else was injured in the wreck, Wegscheider said.
Investigators are working to determine what led to the crash. Wegscheider said there is no indication the driver was under the influence of drugs or alcohol.
