The Alabama skills test
Components: Pre-trip vehicle inspection, Basic control skills, On-road driving test.
Test vehicle: You must provide a vehicle representative of the class and type you intend to drive, meeting safety standards with valid registration and insurance; ALEA does not furnish a test vehicle.
Where and how to book: Skills tests are given at ALEA offices and at ALEA-approved third-party skills-test locations (including CDL schools). Knowledge and skills appointments are scheduled online at alea.gov; appointments are recommended.
Waits and retests: ALEA does not publish official wait times. Third-party school testing often offers faster or more flexible scheduling for a fee.
Practice the inspection part with our pre-trip inspection guide. Research dated 2026-10-12; confirm testing details with Alabama.
