Frequently Asked Questions

What is the difference between ELDT theory and BTW?

Theory covers classroom knowledge (regulations, safety, vehicle systems) and can be done online. BTW (Behind-the-Wheel) is hands-on driving practice on a range and road, which must be done in person.

How many hours of BTW training are required?

FMCSA doesn't specify minimum BTW hours, but requires proficiency. Most quality schools provide 40-80+ hours. Be wary of schools offering less than 40 hours of actual driving time.

Can I do ELDT theory at one school and BTW at another?

Yes! Many students do online theory separately, then enroll in BTW-only training. Both schools must be registered on the TPR (Training Provider Registry).

Does online ELDT theory count toward my training hours?

Yes, online theory from a TPR-registered provider fulfills the ELDT theory requirement. It will be recorded on the Training Provider Registry and your BTW school can verify completion.
