ELDT Theory vs Behind-the-Wheel Training
ELDT is the federal training program. Theory and Behind-the-Wheel are the two course types you need to complete. Here's exactly what each one covers — and where to get them.
ELDT: One Program, Two Types of Training
Entry Level Driver Training (ELDT) is the federally mandated training program required by FMCSA for new CDL applicants. Under this program, there are two distinct types of training you must complete:
Theory Training
Also called “knowledge training” or “classroom instruction.” The textbook side of learning to drive commercially.
- Done online or in a classroom
- Self-paced or instructor-led
- Free at CDL Study Buddy
Behind-the-Wheel (BTW)
Also called “range and road training.” The hands-on driving side of learning.
- In-person only — range + public roads
- Instructor-supervised at all times
- Paid — through a driving school
ELDT Theory Training — In Detail
Theory training is the knowledge-based component of ELDT. Think of it as the “book learning” portion — you're studying the rules, systems, and concepts before you ever touch a steering wheel.
What Theory Training Covers
FMCSA requires Theory training to cover five major curriculum areas (for Class A and B):
Basic Operation
~8 hoursVehicle control systems, dashboard instruments, pre-trip and post-trip inspection procedures
Safe Operating Procedures
~7 hoursVisual search, communications, speed management, space management, night operation, extreme driving conditions
Advanced Operating Practices
~6 hoursHazard perception, skid control and recovery, railroad-highway grade crossings, jackknifing and other emergencies
Vehicle Systems & Malfunctions
~4 hoursIdentification and diagnosis of major vehicle system malfunctions, roadside inspection procedures
Non-Driving Activities
~6 hoursHours of service, driver wellness, post-crash procedures, cargo handling, environmental compliance
How Theory Training Works
- Format: Online (self-paced) or in-person classroom. FMCSA permits either format as long as the provider is TPR-registered.
- Time commitment: Class A: ~31 hours of curriculum. Class B: ~22 hours. Endorsements: 6–10 hours each. No minimum time requirement — you work at your own pace.
- Assessment: Section quizzes (80% pass requirement). Retake as needed until you pass.
- Cost: Free at CDL Study Buddy. Other providers charge $50–$300+ for Theory-only courses.
- Completion reporting: Automatic submission to the FMCSA Training Provider Registry upon passing all quizzes.
ELDT Behind-the-Wheel (BTW) Training — In Detail
Behind-the-Wheel training is the hands-on, practical component of ELDT. This is where you actually get in the truck and learn to operate it under the supervision of a certified instructor.
What BTW Training Covers
BTW training has two parts — range exercises and public road driving:
Range Exercises
- Vehicle inspection (pre-trip)
- Straight-line backing
- Offset backing (alley dock)
- Parallel parking
- Coupling and uncoupling (Class A only)
Public Road Driving
- Urban and rural streets
- Expressways and highways
- Lane changes and merging
- Turns and intersections
- Railroad crossings
How BTW Training Works
- Location: In-person only. You must physically attend a training facility with a practice range and road access. BTW cannot be completed online.
- Time commitment: No federally mandated minimum. Most programs include 30–160+ hours depending on the school and your starting skill level. Training continues until your instructor certifies you as proficient.
- Instructor requirement: Must be supervised at all times by a qualified instructor registered with a TPR-listed provider. No self-directed BTW is allowed under the ELDT mandate.
- Cost: BTW training is not free. Driving school programs range from $25,000+–$10,000. Some trucking companies offer “paid CDL training” where they cover the cost in exchange for a 1–2 year employment commitment.
Theory vs Behind-the-Wheel: Side-by-Side
Who Needs Theory vs Who Needs BTW?
Not everyone needs both. Here's the breakdown by applicant type:
How to Complete Both Types of Training
The most cost-effective path for most students:
Start with Theory — Free Online
Complete your ELDT Theory training first with CDL Study Buddy — it's free and you can do it from your phone. This gets the knowledge portion done before you spend a dime.
Find a BTW Provider
Search the FMCSA Training Provider Registry for BTW providers near you. Look for driving schools that offer BTW-only packages — you already have your Theory done, so you shouldn't pay for it twice.
Complete BTW Training
Attend scheduled sessions, practice on the range, drive on public roads. Your instructor certifies you when you're proficient in all required skills.
Schedule Your CDL Skills Test
With both Theory and BTW completions now on file in the TPR, you can schedule your CDL skills test at your state DMV. Both records will be verified before you test.
Common Misconception
Many students think they can skip Theory if they have driving experience. You can't — FMCSA requires formal ELDT Theory training from a registered provider regardless of your background. Even if you've driven trucks on a farm or in the military, you must complete a registered Theory course before testing.
CDL Study Buddy provides free ELDT Theory training for all Class A, Class B, and endorsement applicants. Complete your Theory online, then find a local BTW provider through the TPR.
