Commercial-driver knowledge preparation

About this practice suite

This suite prepares candidates for commercial-driver knowledge preparation selection in the rail, transit, road transport, maritime, and logistics sector with 5 skill areas: critical thinking, numerical reasoning, situational judgment, attention and concentration and data checking and clerical accuracy. Every question was written by Novus editors for this suite — none are taken from live or leaked exams — and the full bank holds 52 scored questions across three modes, plus 8 reserve questions used to vary repeat attempts. Answer keys never ship to the browser: your answers are scored server-side, and results stay on your device.

Skills this suite practises

• Critical thinking — Evaluating evidence, assumptions, arguments, credibility, and alternative explanations.
• Numerical reasoning — Arithmetic, fractions, percentages, ratios, rates, estimation, word problems, and number relationships.
• Situational judgment — Evaluating workplace responses against role-relevant principles.
• Attention and concentration — Sustained focus, selective attention, and accuracy under time pressure.
• Data checking and clerical accuracy — Matching, filing, coding, record checking, and identifying discrepancies.

Sample questions from the guided bank

Two of the 10 guided-practice questions, shown exactly as they appear in a session. Answers and explanations are not printed here — keys stay on the server — so open guided practice to answer them and see how you did.

1. Before every trip, a commercial driver should complete:

   • A. Passenger ticket audit
   • B. Only a fuel top-up
   • C. A systematic pre-trip vehicle inspection
   • D. Random engine swap

2. You find a steering fluid leak during pre-trip. What is best?

   • A. Do not drive; report defect for repair
   • B. Drive slowly to destination
   • C. Top up and ignore
   • D. Disable steering warning light

Practice modes and timing

Guided practice is untimed-feeling and instructional; the mini-test is a short timed check; the full simulation mirrors a complete sitting. All three draw on separate question sets, so moving up a mode never repeats what you practised.
