Question

with a graduated driver licensing system, a new driver:
must be 18 years old to drive alone
is punished less severely than an experienced driver for traffic violations
increases their driving skills and privileges gradually

Explanation:

A graduated driver licensing (GDL) system is designed to help new drivers gain skills and privileges in stages (like learner's permit, intermediate license, full license) to reduce risks. The first option is incorrect as GDL age requirements vary but focus on stages, not just age 18. The second is wrong as penalties for violations in GDL often are stricter or same, not less. The third option matches the definition of GDL: new drivers progress in skills and privileges over time.

Answer:

increases their driving skills and privileges gradually
