How long you’ll need an SR-22 will vary by state and situation. Most states require an SR-22 for three years. During those three years, you’re required to pay for and file a new SR-22 each time you renew your policy.
If in those three years you commit any dangerous driving offenses, you could be required to extend the length of time you need an SR-22. If you’ve remained free of accidents, you can forfeit the certificate and get back to purchasing regular, low-risk insurance coverage.
