The first of the major snow storms to hit Maryland had just started to fall on Friday, February 5, 2010, when a 2002 Chevrolet Ventura being operated by Carrie Ann Brown drifted to the right and struck a 1987 Mack dump truck. The dump truck, which was under contract with the Maryland State Highway Administration and being operated by Robert Singleton, Jr. of Forest Hill, was parked on the shoulder of the road on standby for the pending snow storm. The accident occurred on Paradise Road in Aberdeen near the I-95 overpass.
The driver of the Chevrolet and her 15 year old daughter were both taken to Bayview Hospital in Baltimore City in serious condition. Brown's two other children were also transported to nearby medical facilities for less serious injuries. Hazardous road conditions were believed to be the cause of the accident.
