Theory is the classroom (or online) part of ELDT; range and public road are the two behind-the-wheel parts. A school can register different locations for different parts, so ask where each part happens.

Verify before you pay. FMCSA adds and removes providers every day, and has removed thousands since late 2025. Search the provider name on the FMCSA Training Provider Registry the week you enroll.
