Final answer:
If someone is caught selling or possessing a controlled substance while operating a vehicle, their driving license may be suspended or revoked, in addition to facing other potential legal penalties such as fines or jail time.
Step-by-step explanation:
Selling or possessing a controlled substance while operating a motor vehicle could get your license suspended or revoked. The specific consequences can vary depending on the laws of the state or country in which the offense occurs, as well as factors such as the amount of the substance, the type of substance, prior offenses, and whether there was an intent to distribute. Generally, a person caught in the act will face legal penalties including fines, jail time, and the loss of driving privileges. Some jurisdictions may offer diversion programs or treatment options as alternatives to incarceration for first-time offenders or those with substance abuse problems.
