CDL · Following distance
The road is slippery, and it is daytime. What does the CDL manual advise about your following distance?
Correct answer: Leave a much bigger gap than you would in ideal conditions.
Answer options
- ALeave an extra bus length for every 10 mph of your speed
- BLeave a much bigger gap than you would in ideal conditions Correct
- CLeave an extra bus length for every 10,000 pounds of vehicle weight
Why
Slippery pavement means it takes much longer to stop, so the spacing that works on dry roads falls short. Keep far more room than the normal guideline of a second for each 10 feet of length, plus one extra second above 40 mph.
