2. You are driving a 40-foot vehicle at 35mph. The road is dry, and visibility is good. What is the least amount of space you should keep in front of your vehicle to be safe?
Detailed Explanation
Allow four seconds: 40 feet divided by 10 equals four. At 35 mph, the additional second for speeds above 40 mph does not apply.
Official reference: New York CDL-10, Section 2.7.1: Space AheadCorrect Answer: 4 seconds
Why This Matters on the CDL Test
Measure the gap by timing passage of a fixed roadside landmark.
How to Remember It
Length first, then speed; slippery roads need more space.

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.
