Which of the following violations warrants 12 points on your driving record?

Manslaughter or negligent homicide resulting from the operation of a motor vehicle is a severe offense that involves causing the death of another person due to negligent or reckless driving behavior. In Maryland, such serious violations are treated with the utmost severity and can lead to a significant accumulation of points on an individual's driving record, specifically 12 points. This high point assessment reflects the dangerous and life-threatening nature of the offense, as it involves the loss of life and emphasizes the responsibility that drivers have to operate vehicles safely and considerately.

In contrast, the other options, while certainly dangerous and subject to penalties, do not carry the same level of severity in terms of consequences and point accumulation. Speeding, running a red light, and failure to yield are serious infractions that can lead to accidents and injuries, but they do not inherently involve the same degree of reckless behavior leading to fatal outcomes. Therefore, they result in fewer points on a driving record when compared to the offense of causing death through negligent operation of a vehicle.
