Which offense leads to mandatory revocation by DMV?

Answer: B — Manslaughter

The offense that leads to mandatory revocation by the DMV is manslaughter. This is because manslaughter involves taking another person's life, often as a result of reckless or negligent driving behavior. Such a severe offense indicates an extreme disregard for the safety of others on the road, and as per North Carolina law, it warrants a serious consequence that includes the mandatory revocation of the individual's driving privileges. In contrast, driving without a valid permit, while illegal, typically results in fines or other administrative penalties rather than mandatory revocation. Speeding violations, depending on their severity, might lead to points on a driving record or increased insurance premiums but do not automatically cause a mandatory license revocation. Driving below the speed limit is not an offense at all and would not result in any penalties related to license revocation. Thus, manslaughter stands out as the offense that triggers automatic revocation due to its serious nature.
