280. What should you do if a car coming towards you at night keeps its high beams on?
Detailed Explanation
The correct answer is "Look to the right edge of your lane or the right edge of the road.". This question tests general CDL knowledge and the safest action expected of a commercial driver. The question asks for an action, so choose the step that controls the immediate hazard before convenience or speed.
Correct Answer: Look to the right edge of your lane or the right edge of the road.
Why This Matters on the CDL Test
Use this as part of your General Knowledge review. The real CDL knowledge test rewards drivers who understand the reason behind each rule, not only the answer letter, so read the explanation and then try a few related questions.
How to Remember It
Say the rule in your own words, then explain why the wrong answers are unsafe or incomplete. That habit makes similar General Knowledge questions easier when the exam changes the wording.
Answer Review
Choose "Look to the right edge of your lane or the right edge of the road." because this answer matches the safe CDL action for general knowledge knowledge. On the knowledge test, the safest answer is usually the one that protects space, control, visibility, legal compliance, or inspection accuracy before the vehicle is put at risk.
Why the other answers are weaker
- Flash your high beams at the other driver."Flash your high beams at the other driver." does not best answer this general knowledge knowledge question. When you see a similar option on the CDL permit test, compare it against the exact safety rule and choose the answer that prevents the most immediate risk.
- Slow down and look straight ahead in your lane."Slow down and look straight ahead in your lane." does not best answer this general knowledge knowledge question. When you see a similar option on the CDL permit test, compare it against the exact safety rule and choose the answer that prevents the most immediate risk.
Test-Day Checklist
- Read the question once for the topic, then read it again for the exact CDL action being tested in General Knowledge.
- Eliminate answers that sound convenient but skip an inspection, warning sign, or safety step.
- Say the correct rule out loud before moving on so you can recognize it when the exam changes the wording.
