The crash happened on North Ocean Avenue in Holbrook at about 10:20 p.m. on Thursday, April 21, the Suffolk County Police Department said.
SCPD said Pauline Ross was driving a 2020 Hyundai Elantra south when the car struck a 50-year-old Medford man who was walking in the roadway.
The man was hospitalized for serious, non-life-threatening injuries, police said.
