What violation occurs if a driver does not yield to a bicycle, motor scooter, or motorcycle?

When a driver fails to yield to a bicycle, motor scooter, or motorcycle, this violation is typically categorized under the rules governing right-of-way for vehicles and non-motorized road users. This is consistent with traffic laws designed to protect more vulnerable road users, such as cyclists and motorcyclists.

The correct choice indicates that such a violation incurs 4 points on the driver's record. Accumulating points is a common method used by states to track driving behavior and to penalize unsafe practices on the road. The accumulation of points can lead to further consequences, such as increased insurance rates or even suspension of driving privileges if a driver reaches a certain threshold of points. Thus, the severity of the action—failing to yield—which can lead to accidents, justifies a heavier penalty in terms of point accumulation.

The other options reflect either a lighter penalty or a warning, which do not adequately account for the seriousness of the infraction related to yielding to other vulnerable road users.
