What consequence might a driver face for a drug-related infraction?

A driver involved in a drug-related infraction may face license suspension as a significant consequence. This action is taken to prevent unsafe driving and ensure public safety, as driving under the influence of drugs can impair a person's ability to operate a vehicle effectively. When a driver is caught violating laws related to controlled substances—whether through possession or operating a vehicle while impaired—the authorities may impose a suspension of the driver’s license in addition to other penalties.

In contrast, the other options represent less severe outcomes that do not adequately reflect the serious nature of drug-related offenses. Just fines may apply in some cases, but they typically accompany more severe consequences like license suspension. A warning only would not be appropriate for a drug-related violation, given the potential risks involved. Vehicle inspection does not directly address the infraction and would not be a related consequence for drug use or possession while driving. Thus, license suspension serves as a necessary disciplinary measure to maintain road safety.
