What is the maximum weight limit for a 5-axle combination vehicle?
  • 80,000 pounds
  • 34,000 pounds
  • 20,000 pounds
  • 100,000 pounds
This is a question from page 4 - click here to look up the answer

Quote From Page 10 Of The Illinois CDL Manual:

Weight

The maximum weight limits on both designated and non-designated streets and highways are:

  • 20,000 pounds on a single axle.
  • 34,000 pounds on a tandem, and
  • Up to 80,000 pounds of total weight on a 5-axle combination, depending upon axle spacing.
  • 20,000 pounds on a single axle
  • 34,000 pounds on a tandem
  • 80,000 pounds on a 5-axle combination, depending upon axle spacings.

TruckingTruth's Advice:

A "tandem" is a reference for a pair of axles. For example, the rear 2 axles on a tractor and the rear two axles on the trailer are considered tandems. So a single axle (such as the front axle) can have a maximum of 20,000 pounds. A tandem (two axles in close proximity) may have 34,000 pounds. But the entire weight of the vehicle can not exceed 80,000 pounds.

Following too closely is considered a serious traffic violation. Which of these is considered following too closely?
  • Less than 12 seconds of following distance
  • Failure of a truck to leave sufficient distance for being overtaken by another vehicle
  • Less than 8 seconds of following distance
  • Less than 400ft of following distance
This is a question from page 3 - click here to look up the answer

Quote From Page 9 Of The Illinois CDL Manual:

Following Too Closely:

  • Following the vehicle ahead too closely.
  • Failure of a truck to leave sufficient distance for being overtaken by another vehicle.

TruckingTruth's Advice:

While the CDL manual specifically states "failure of a truck to leave sufficient distance for being overtaken by another vehicle" there are many scenarios in which a driver can be charged with following too closely. But that is the answer you'll most likely see if asked on an exam.

Following too closely is considered a serious traffic violation and carries with it additional consequences. Two serious traffic violations within a three-year period results in a two-month disqualification. Three serious traffic violations in the same period results in a four-month disqualification.

Following too closely is one of the most dangerous things you can do. Keeping plenty of following distance is absolutely critical to safe driving.
