A 23-year-old woman and her 1-year-old son were hit by an SUV at the intersection of Washington and Jackson streets in downtown Sonora Tuesday night.

A 1999 white Ford SUV, driven by a 78-year-old Sonora man, was traveling northbound on Washington Street and struck the Woodland residents as they were crossing Washington in the crosswalk, according to a Sonora Police Department news release.

Both the mother and the son sustained moderate to severe injuries and were transported out of the county for treatment.

The police department said their injuries are not life threatening.

The cause of the collision was not known Wednesday afternoon, and the investigation is ongoing, police said.

According to Sonora Police Department logs, the collision was reported at 7:55 p.m. when a witness saw a “female pulled out from under a truck.”

Sgt. Tim Wertz at the Sonora Police Department said the department was not yet announcing names of the parties involved in the accident, and that pending call volumes in the coming days, a detailed report could be released within a week.

Wertz said witnesses reported that the woman was following a group of nine other people. The driver did not see her, and struck both her and the child at the same time.

Wertz added that the department was still garnering and analyzing witness statements to determine where the child was, but they did know the child did not fly through the air after the impact.

At least seven people saw the accident, he said.

During the course of the investigation, the officers marked where the car ended up after the accident, Wertz said.

The child was transferred to UC Davis Medical Center in Sacramento, while the woman was transferred to a Modesto area hospital.

The pedestrian accident comes just days after the second joint California Highway Patrol and Sonora Police Department pedestrian safety enforcement operation conducted at various sites around Sonora, including Washington Street.

The most recent pedestrian safety operation, held on Sept. 8, garnered 30 total citations for crosswalk violations, cellphone use and seatbelt violations.

Law enforcement conducted the operation on Washington Street at Elkin Street, Greenley Road at Guzzi Lane, and Parrotts Ferry Road at State Street.

During the first of the operations, held on Aug. 29, law enforcement issued eight crosswalk right-of-way citations, among 35 tickets for cellphone and seatbelt violations.

The sites of the operation included the intersection of Highway 49 and School Street, Greenley Road and Guzzi Lane, and North Washington Street and Dodge Street.

Pedestrians could also be warned for crosswalk violations if they suddenly stepped into the path of an approaching vehicle and constituted a hazard for either themselves or the motorists, but none were issued during either operation.

The pedestrian safety operations were initiated after a spate of vehicle on pedestrian accidents raised an outcry from the community regarding vehicle safety on thoroughfares frequently used by pedestrians.

A Statewide Integrated Traffic Records System (SWITRS) heat map distributed by a Caltrans official at a city of Sonora merchants meeting at the end of June indicated that 50 collisions occurred on Washington Street between Stockton Road and Elkin Street in downtown Sonora from 2010 to 2016.

The heat map from SWITRS was based on provisional data provided to the state and came from a different database system than is used by Caltrans.

Caltrans previously identified 17 collisions occurred between vehicles and pedestrians or vehicles and bicycles between 2010 and 2014, based on a March Traffic Safety Division investigation of Highway 49 in Sonora, which includes data from unidentified side streets also in the downtown area.

About 16,250 vehicles travel on the street each day, of which about 7 percent are commercial trucks. About 1,600 vehicles travel on the street per hour during peak times of the day.
