An advocate for Saskatchewan motorcycle riders is out of hospital today after her bike was involved in a serious crash.

The woman who was injured, Rhonda Cwynar, is president of Riders Against Government Exploitation (RAGE), a group formed last year in response to proposed insurance rate hikes.

She was taken to Regina General Hospital after the collision Monday night.

A photo of the crash showing debris from the motorcycle underneath the wheels of a sport utility vehicle has been posted on Facebook.

Cwynar said her bike was rear-ended by the speeding SUV. She ended up with a broken ankle, a broken collar bone and various scrapes and bruises.

"I was at the bottom of all that," Cwynar wrote on Facebook. "I am still in shock."

Regina police said they were called to a collision at 9:51 p.m. CST at Albert Street and the South Service Road. 

Another person involved in the crash has been charged in connection with this incident.

Charges include impaired driving causing bodily harm and having a blood-alcohol level over the legal limit.

However, Regina police were providing no further details, saying the case is under a publication ban.
