Sample Wisconsin CDL Test Questions - General Knowledge

Question 1

When a commercial vehicle is stopped on a one-way or divided highway, where should the three reflective triangles be placed?

  1. A 10 feet, 100 feet, and 200 feet toward approaching traffic
  2. B 25 feet, 100 feet, and 250 feet toward approaching traffic
  3. C 50 feet, 100 feet, and 300 feet toward approaching traffic
  4. D 75 feet, 100 feet, and 400 feet toward approaching traffic

Correct answer: A – 10 feet, 100 feet, and 200 feet toward approaching traffic

The Wisconsin Commercial Driver’s Manual directs drivers to place warning devices 10 feet, 100 feet, and 200 feet toward approaching traffic on a one-way or divided highway. The devices must be set out within 10 minutes when a commercial vehicle is stopped on the roadway or shoulder. This arrangement gives approaching drivers progressively earlier warning.

Question 2

A heavy vehicle is approaching a downhill exit ramp that curves. What should the driver do?

  1. A Enter at the ramp’s posted speed regardless of the load
  2. B Reduce to a safe speed before reaching the curve
  3. C Wait until inside the curve before downshifting
  4. D Shift to a higher gear before entering the ramp

Correct answer: B – Reduce to a safe speed before reaching the curve

Downhill ramps that also curve are particularly hazardous for commercial vehicles. The downgrade makes speed reduction more difficult, and braking while turning can reduce stability. Slow to a safe speed before entering the curved portion of the ramp and select the proper gear before the curve.

Question 3

An unblocked cargo article is longer than 5 feet but no longer than 10 feet. What is the minimum number of tiedowns required?

  1. A 1
  2. B 2
  3. C 3
  4. D 4

Correct answer: B – 2

Federal cargo-securement rules require at least two tiedowns for an article that is longer than 5 feet but no longer than 10 feet when it is not blocked against forward movement. This requirement applies regardless of the article’s weight. A shorter article weighing 1,100 pounds or less may qualify for a one-tiedown minimum.

Question 4

What does an orange WORKERS warning sign indicate?

This sign warns drivers that _____________.
  1. A Only road workers need to obey the sign
  2. B Workers may be in or near the roadway
  3. C The roadway is completely closed ahead
  4. D All traffic must follow a posted detour

Correct answer: B – Workers may be in or near the roadway

In Wisconsin, the WORKERS sign alerts road users that workers may be in or near the roadway. It does not by itself indicate that the road is closed or that a detour is required. Work zones may also contain construction vehicles, narrowed lanes, sharp turns, or uneven surfaces, making slower and more careful driving necessary.

Question 5

What action is directed by a SLOWER TRAFFIC KEEP RIGHT sign?

This sign indicates that drivers ___________.
  1. A Use the right-hand lane when traveling slower than other traffic
  2. B Remain in the right lane for the entire trip
  3. C Pass slower vehicles on their right
  4. D Increase speed until you match the fastest traffic

Correct answer: A – Use the right-hand lane when traveling slower than other traffic

Wisconsin’s SLOWER TRAFFIC KEEP RIGHT sign directs traffic moving more slowly than the general flow to use the right-hand lane. It does not prohibit every lawful use of another lane or authorize passing on the right in all situations. Keeping slower traffic right leaves the left lane available for passing when appropriate.

Question 6

Which hazard classes are listed under closed-cargo-space guidance as prohibited from overhang or tailgate loading?

  1. A Class 1 explosives only
  2. B Class 4 flammable solids only
  3. C Class 5 oxidizers only
  4. D Classes 1, 4, and 5

Correct answer: D – Classes 1, 4, and 5

Classes 1, 4, and 5 are all included in the closed-cargo-space guidance on overhang and tailgate loads. Federal hazardous-materials regulations contain specific loading requirements for Class 1 materials and require Class 4 and Class 5 lading to be contained within the vehicle body, covered, and transported with any tailgate secured, subject to stated exceptions.

Source: Wisconsin Commercial Driver’s Manual — § 9.4, “Use Closed Cargo Space”, 49 CFR § 177.835 — Class 1 (Explosive) Materials, 49 CFR § 177.838 — Class 4 (Flammable Solid) Materials, Class 5 (Oxidizing) Materials, and Division 4.2 (Self-Heating and Pyrophoric Liquid) Materials
