Why plan early
An expired license, medical certificate or endorsement can take a driver off the road immediately. Some renewals involve appointments, background checks or exams that take weeks to schedule.
Typical renewal considerations
Requirements vary by credential and jurisdiction. Always confirm with the issuing agency.
- CDL: renewal periods and steps are set by each state licensing agency.
- DOT medical certificate: issued for up to 24 months by a certified medical examiner; keep your state informed of the new certificate.
- Hazmat (H) endorsement: requires a TSA security threat assessment, which can take time to process.
- TWIC and other site credentials have their own expiration dates.
Frequently asked questions
Do you store my dates?
No. The planner runs in your browser and does not save the dates you enter.
How early should I start a hazmat renewal?
Many drivers start 60–90 days ahead because the security threat assessment can take several weeks. Check your state's guidance.
