Should a 20-Year-Old Stay on Their Parents' Policy?
For most 20-year-olds in Washington, staying on a parent's policy is the smarter financial choice — often by a large margin.
Separate Policy

Added to Parents' Policy
$306/mo
$3,669/year
Potential Savings: $125/month
20-year-olds in Washington save an average of $1,500/year by staying on their parents' policy vs. buying separately.
When staying on parents' policy makes sense:
- You live at the same address (or at college full-time)
- The car is titled in your parents' name or jointly
- You're still financially dependent on your parents
When you need your own policy:
- You've moved to a different state
- You bought a car in your name only
- Your parents' insurer won't add you
