What must the BMV require of drivers aged 21 or older convicted of 2 or more traffic offenses within a year?

The correct answer is traffic school. When drivers aged 21 or older accumulate two or more traffic offenses within a year, the Bureau of Motor Vehicles (BMV) mandates that these individuals attend traffic school. This requirement serves to educate drivers on safe driving practices, reinforce adherence to traffic laws, and ultimately reduce the risk of future offenses. Traffic school programs are designed to improve a driver's understanding of road safety and responsible driving behaviors.

Other options, while they address various aspects of driving or legal consequences, do not specifically reflect the BMV's structured program aimed at rehabilitating drivers who have shown a pattern of unsafe driving. Drug testing, community service, and increased insurance coverage could be applicable in different situations or jurisdictions, but they are not standard requirements imposed by the BMV in response to multiple traffic violations for the specified age group.
