Getting your CDL for the first time can feel overwhelming — there are written tests, skills tests, medical exams, training requirements, and a dozen acronyms to learn. This guide walks you through the entire process from zero experience to CDL in hand, in the right order.

Step 1: Verify Basic Eligibility

Before anything else, confirm you qualify:

Step 2: Get Your DOT Medical Certificate

Before you can obtain your CDL (or in some states, even your CLP), you need a DOT medical exam performed by a certified medical examiner. The exam checks:

Cost: $50–$150. Find a certified medical examiner at fmcsa.dot.gov/medical-programs/nrcme. Your certificate is valid for 2 years (or less if your doctor notes health conditions to monitor).

Step 3: Study for the Written Tests

This is where most people start — and where you'll spend the most time before the DMV. You need to pass:

Study timeline: 10–14 days of focused preparation is enough for most drivers. Use greenlightcdl.com/test/ for 482 practice questions built from the official CDL manual.

Step 4: Get Your Commercial Learner's Permit (CLP)

Visit your state's DMV with:

Pass all your written tests at the DMV and you'll walk out with your Commercial Learner's Permit. Federal law then requires a minimum 14-day hold before you can take the CDL skills test.

Step 5: Complete ELDT (Entry-Level Driver Training)

Since February 2022, all new CDL applicants must complete ELDT through a federally registered provider before taking the skills test. ELDT has two parts:

Complete ELDT during your 14-day CLP hold period to avoid delays. Your provider reports completion electronically to the federal Training Provider Registry.

Step 6: Schedule and Pass Your CDL Skills Test

The skills test has three parts:

  1. Pre-trip inspection: Walk around the vehicle and verbally identify and check all major components (30–45 minutes)
  2. Basic vehicle control: Straight-line backing, alley dock or offset backing, and possibly parallel parking on a closed course
  3. On-road driving: 30–60 minutes of actual road driving with an examiner. Covers traffic, turns, lane changes, intersections.

Book your skills test appointment the same day you receive your CLP — scheduling backlogs can be 2–4 weeks in many states.

Step 7: Apply for Your CDL

After passing the skills test, return to the DMV (or in some states, you're issued the CDL at the test site) to officially convert your CLP to a full CDL. You'll pay a CDL issuance fee ($25–$60).

What Does a CDL Cost?

The single best investment you can make before the DMV is thorough written test preparation. Most drivers who fail the written test lose a week or more of progress waiting to retest. Pass it the first time. Start studying at greenlightcdl.com/test/ today.
