Class A vs. Class B (License Class Selection) for the CDL Exam — French candidates

5% of the CDL test plan. Class A allows combination vehicles (truck + trailer >10,000 lb GVWR); Class B is single-vehicle only. Selecting the right class up-front saves money and matches career intent. Calibrated for French candidates.

Most exam coaching covers the curriculum at the same depth across all topics. That misses the asymmetry of high-stakes testing: a few topics carry disproportionate weight on the score. Class A vs. Class B (License Class Selection) sits at roughly 5% of the Commercial Driver License content distribution — Class A is required for over-the-road tractor-trailer driving (the dominant CDL career path). Class B covers straight trucks, dump trucks, school buses, and most municipal vehicles. A Class A holder can drive any Class B vehicle (with appropriate endorsements); a Class B holder cannot drive Class A combinations. Pass rates for the CDL are published annually by the awarding body and vary by cohort and locale. For French candidates preparing for CDL, the calibration of study to local context matters: France's domestic credentials are the Baccalauréat (school leaving) and DELF/DALF (French proficiency). IELTS and Cambridge are common for English certification.

Pass rates for CDL (France) are published periodically by the awarding body.

Common failure modes

These are the patterns that cause most candidates to lose marks on this topic. Recognising them in advance is half the work.

  • !Choosing Class B because the training is shorter, then realising the desired employer requires Class A
  • !Confusing GCWR (combination weight rating) with GVWR (single vehicle weight rating)
  • !Not realising school bus drivers need a Class B with P+S endorsements (or Class A in larger districts)

Study tips

  • 1Check 5+ job postings for your target employer/role and confirm whether they require Class A or Class B before selecting your training program.
  • 2If undecided, choose Class A — it covers everything Class B does plus combination vehicles.
  • 3For local delivery and municipal jobs, Class B with appropriate endorsements (P, S, T, N, X, H) is often sufficient.
  • 4Les candidats français préparant le CDL doivent privilégier les ressources alignées sur le CECRL — les niveaux B2 et C1 sont systématiquement attendus pour les programmes de mobilité internationale.
