HARFORD COUNTY, Md. — A devastating multi-vehicle crash involving two passenger vehicles and a Harford County Public School bus left one teenager dead and another seriously injured Thursday afternoon, according to the Harford County Sheriff’s Office (HCSO).
The Collision
Shortly after 2 p.m. on September 18, 2025, deputies from HCSO, along with allied law enforcement agencies, the Harford County Department of Emergency Services, and local fire companies, responded to the area of Route 543 and Crescent Knoll Drive for reports of a serious vehicle collision.
Upon arrival, first responders found two heavily damaged passenger vehicles and a school bus carrying students. Immediate medical aid was rendered to all involved, and aviation support was requested from the Maryland State Police to airlift the most severely injured victim.
Preliminary Findings
According to an initial investigation by deputies assigned to the HCSO Traffic Unit, the crash occurred when a vehicle traveling northbound on Route 543 stopped properly and was waiting to make a left turn onto Crescent Knoll Drive.
The stationary car was then struck from behind by another vehicle driven by a 39-year-old man, propelling it into the path of a southbound Harford County Public School bus.

The driver of the struck vehicle, a 17-year-old male, sustained significant injuries and was airlifted to a local trauma center.
