A Parks Department sanitation truck struck a 78-year-old woman using a motor-assisted wheelchair in the Eighth Avenue bike lane this morning shortly before 10 a.m., just north of Bleecker Street. The victim suffered head trauma and was taken to St. Vincent’s Hospital, where she is in serious condition, a police spokesman said. No further details on the collision are available at this time. NYPD said the investigation is ongoing.

The driver was heard repeating that he "didn’t see" the victim, according to Michelle Ernst of the Tri-State Transportation Campaign, who passed the scene of the crash this morning and sent in this picture.

Streetsblog has requests in with DOT and the Parks Department to determine if a policy is in place governing the use of protected bike paths by city vehicles. We’ll post more information as it becomes available.
