DOVER - Three young brothers were injured in a single vehicle crash Sunday night, including an 8-year-old boy who was hospitalized in critical condition with a head injury, police said.

According to Dover Police, the boys’ mother, Ashley Shaffer, 31, of Smyrna, was charged with multiple traffic offenses after her vehicle crashed while traveling northbound on Bay Road at approximately 6:40 p.m. The Chevrolet Blazer was approaching the north intersection of the Blue Hen Corporate Center when it swerved to the left, then right before rolling over at least three times, authorities said.

The three boys ages 4, 5, and 8 were ejected from the vehicle, Dover Police said. All three children had been seated in the rear of the vehicle but were not wearing seat belts and car seats/booster seats were not in the vehicle, according to spokesman Master Cpl. Mark Hoffman.

Ms. Shaffer allegedly said she was changing the radio as she approached the intersection and noticed the light had turned red, police said. The driver suddenly swerved to avoid traffic that was in the intersection at the time, police said.

The 4- and 5-year-old children were treated and released from Bayhealth-Kent General Hospital with minor injuries. The 8-year-old was listed in critical condition at A.I. DuPont Children’s Hospital on Monday.
