General Knowledge for the CDL Exam — Visayas candidates

20% of the CDL test plan. The General Knowledge test (50 multiple-choice questions) is required for every CDL class and covers vehicle systems, road rules, and emergency procedures. Calibrated for Visayan Filipino 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. General Knowledge sits at roughly 20% of the Commercial Driver License content distribution — Every CDL applicant takes General Knowledge. Topics include vehicle inspection, basic control, shifting, communicating with other drivers, accident procedures, and driver wellness. Pass rates for the CDL are published annually by the awarding body and vary by cohort and locale. For Visayas candidates preparing for CDL, the calibration of study to local context matters: Cebu City is the second-largest test-taker hub in the Philippines for NCLEX, IELTS, and TOEFL. Visayas-based nurses commonly sit NCLEX in Cebu before applying for U.S. work visas.

Pass rates for CDL (Visayas, Philippines) 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.

  • !Misidentifying the controlled-braking vs stab-braking technique
  • !Confusing the proper following distance rule (1 second per 10 ft of vehicle length, plus 1 second above 40 mph)
  • !Wrong answer on hazardous-conditions reduced-speed rules
  • !Confusing the disqualification offences (DUI, reckless, leaving the scene)

Study tips

  • 1Drill following-distance math: 50 ft trailer at 35 mph = 5 seconds; at 50 mph = 6 seconds.
  • 2Memorize disqualification offences and their durations — first DUI = 1 year, second = lifetime.
  • 3Practice stab-braking vs controlled braking with the FMCSA definition.
  • 4Know the wellness requirement: 8 hours sleep, no driving over 11 hours after 10 off.
  • 5NCLEX-RN must currently be taken in Manila — there is no Pearson VUE NCLEX site in the Visayas. Budget Manila travel and accommodation when planning your test date.
  • 6IELTS is available in Cebu at British Council and IDP centres; Cebu speaking-test slots are typically less booked than Manila and quicker to schedule.
  • 7For nursing English-language preparation: PRC (Professional Regulation Commission) cebu hosts review centres that align both NCLEX and IELTS preparation tracks.

    You should keep how many seconds of following distance for every 10 feet of vehicle length at speeds below 40 mph?

    • A1 secondCorrect
    • B2 seconds
    • C3 seconds
    • D5 seconds
    Why this answer?

    The CDL rule is 1 second per 10 feet of vehicle length below 40 mph. Above 40 mph, add 1 second. A 60-foot rig at 55 mph thus needs 7 seconds of following distance.
