General Knowledge · Question 54

When approaching a curve on a downgrade, you should:

  • A Coast through in neutral
  • B Accelerate to climb out of the curve
  • C Brake hard inside the curve
  • D Reduce speed before the curve and stay in your gear through it Correct answer

Why this is the correct answer

Slow before the curve, then maintain a steady speed through it. Braking inside a curve shifts weight and reduces tire grip.

How this topic appears on the test

The General Knowledge CDL exam covers Speed management as a recurring theme. Test-writers favor questions that probe whether the applicant has internalized the safe operating procedure, not merely memorized the rule. When you encounter a question on this topic, slow down and verify that the answer you've chosen describes what a careful, defensive driver would actually do — not what is technically permissible.

If you missed this question, that's exactly the right outcome of a practice session: the goal is to surface gaps before the actual test. Open your state CDL manual to the Speed management section and re-read the relevant subchapter. Then come back and run through the rest of the General Knowledge practice exam.
