Quote From Page 8 Of The Illinois CDL Manual:

Excessive Speeding Excessive speeding involving any single offense for any speed of 15 mph or more above the posted speed limit.

  • Failure to reduce speed to avoid an accident.
  • Driving too fast for conditions.
  • Exceeding the speed limit in a school zone.

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.

So make sure you get all of the endorsements.
