CDL · Following distance

When you drive in daylight on a slick road, how should you change your following distance, according to the CDL manual?

Correct answer: Increase it well beyond what you would use in ideal conditions.

Answer options

  1. AIncrease it well beyond what you would use in ideal conditions. Correct
  2. BAdd one car length for each 10,000 pounds your rig weighs.
  3. CKeep it the same, since daylight makes up for the slick surface.

Why

The basic rule of one second for each 10 feet of vehicle length, plus one extra second above 40 mph, is meant for good conditions. On a slippery road you need much more room than that, because it takes far more distance to stop.
