Police said the 35-year-old mother was distracted by her kids in the back seat of her vehicle last September when she crashed into 22-year-old Shomette on Bland Boulevard.
Shomette stopped on the side of the road to help a family stuck on the side of the road with a flat tire.
A Newport News traffic court judge sentenced Stappert to 12 months in jail, but suspended 11 months, leaving her with a month to serve on the weekends.
Online court records said Stappert's license will be restricted for six months.
Judy Dunn, Shomette's grandmother, told NewsChannel 3 she would rather Stappert's license be permanently revoked instead of her receiving any jail time.
Attempts to reach Stappert for comment have not been returned.
