Arguments for Raising the Driving Age to 21

Evidence-Based Reasons

1. Crash Risk: Teens (16–19) have 3× fatal crash rate per mile vs. 20+ (NHTSA).
2. Risk Behaviors: Higher speeding, DUI, seat-belt non-use, distraction (phone, peers).
3. Lives Saved: IIHS estimates 13% fewer teen fatal crashes → ~1,300 lives/year.
4. Brain Development: Prefrontal cortex (judgment, impulse control) matures mid-20s; 21 closer to maturity.
5. Parental Supervision: Longer learner period = more coached practice.
6. Insurance Costs: Lower teen crash rates reduce societal premium burden.
7. International Precedent: Many countries set minimum at 18–21 with better safety records.
8. Graduated Licensing Enhancement: Extends supervised phase before full independence.
9. Public Support: Polls often show majority favor higher age.
10. Consistency: Aligns with legal adulthood for alcohol, firearms, contracts.
