UPDATE45:15 p.m. 12/14/2021: The Calvert County Sheriff’s Office Crash Reconstruction Unit has been working throughout the night to determine the causation and contributing factors to the fatal crash that occurred on Rt. 4 at Calvert Beach Road in St. Leonard, MD on December 13, 2021.

Based on the numerous witness statements from citizens who saw the collision occur, physical evidence collected on the scene, and vehicle evidence, it has been determined that the driver of the Jeep Compass Failed to Stop at a Dedicated Left Turn Light, Failed to Obey a Traffic Control Signal and Failed to Yield the Right of Way. At the time of the crash, the signal was a solid red left-turn arrow. The Ford F-250 vehicle that was traveling northbound on MD Route 4 entered the intersection on a green signal.

The Calvert County Sheriff’s Office Crash Reconstruction Unit is continuing the investigation and a full report will be forthcoming once all the evidence is analyzed and reports from partner agencies are obtained.
