Primary sources first
Every guide is built from official sources, such as testing organizations, federal and state agencies, and regulations. We link those sources at the bottom of each page so you can verify anything yourself.
Prices and statistics
Prices (for example eye exam or DOT physical costs) are typical ranges reported by patients and providers. They are not quotes. We label them as estimates and tell you to confirm with your local provider. Pass rates are rounded historical figures from the administering organizations.
Review and updates
Each page shows a “Last reviewed” date. We re-check guides when rules, formats or fees change, and at least once a year.
Not professional advice
Our content is educational. It is not medical, legal or financial advice. For decisions about your health, legal matters or finances, consult a qualified professional.
