How we check

• Official sources only. Test sites come from the state licensing agency's own published list (DMV, OMV, DPS or similar). Rules come from the state agency, FMCSA or the federal regulations. Tester details come only from the state list or the tester's own website.
• No guide sites. We don't copy from CDL guide sites, school-review sites or job boards. Our build refuses to publish anything sourced from one.
• No guesses. If the state doesn't publish an address or a fee, we write "Not published".
• Dated. Every entry shows when we last checked it.
• Independent. We're not affiliated with any state agency, FMCSA, school or tester.
• Corrections welcome. Saw something different? Email toffee@mail.grokbot.com.
