Sample Wisconsin CDL Test Questions - General Knowledge

Question 1

When selecting a parking position, what should you try to arrange?

  1. A Easy access to the vehicle's cargo doors
  2. B A forward-moving departure without backing
  3. C A backing distance of no more than 10 feet
  4. D A space immediately beside an entrance ramp

Correct answer: B – A forward-moving departure without backing

Backing is dangerous because the driver cannot see everything behind a commercial vehicle. When possible, park where you can move forward when leaving. If backing is unavoidable, inspect the path, back slowly, use both mirrors, favor the driver's side, and use a helper when one is available.

Question 2

What does a yellow NARROW BRIDGE warning sign indicate?

This sign warns drivers that _____________.
  1. A The bridge roadway is narrower than the approaching travel lanes
  2. B The bridge structure is unstable
  3. C All traffic must stop and wait for an escort
  4. D Drivers should accelerate before reaching the bridge

Correct answer: A – The bridge roadway is narrower than the approaching travel lanes

In Wisconsin, the NARROW BRIDGE sign warns that the bridge's driving area is narrower than the approach lanes or meets specified narrow-width conditions. It does not identify an unstable structure. It also does not necessarily mean opposing vehicles cannot pass; a ONE LANE BRIDGE sign provides that separate warning.

Question 3

Which vehicle configuration is especially likely to become hung up on a raised railroad crossing?

  1. A A commercial vehicle with a damaged tire
  2. B A straight truck with worn shock absorbers
  3. C A low-slung trailer or a single-axle tractor pulling a long trailer
  4. D A vehicle equipped with a manual transmission

Correct answer: C – A low-slung trailer or a single-axle tractor pulling a long trailer

Low-slung units such as lowboys, car carriers, moving vans, and possum-belly livestock trailers can become stuck on raised crossings. A single-axle tractor pulling a long trailer may also hang up when the landing gear is positioned for a tandem-axle tractor. Drivers must consider underbody clearance before crossing.

Question 4

A yellow warning sign showing a truck descending a steep slope means:

This sign warns drivers ______________.
  1. A A downgrade is ahead; prepare to control your speed
  2. B You must yield to trucks entering the highway
  3. C Water-hauling vehicles frequently cross ahead
  4. D Commercial vehicles are prohibited beyond the sign

Correct answer: A – A downgrade is ahead; prepare to control your speed

The hill sign warns of a significant grade ahead. A commercial driver should select a safe speed and shift to the proper low gear before beginning a downgrade. Vehicle weight, grade length and steepness, road conditions, and weather all affect the safe descent speed.

Question 5

For cargo subject to driver inspection, when must the load and its securement be checked?

  1. A Only before beginning the trip
  2. B At departure and at the first scheduled fuel stop
  3. C Before driving, within 50 miles, and later at duty-status changes or after 3 hours or 150 miles, whichever occurs first
  4. D Only after the first 25 miles

Correct answer: C – Before driving, within 50 miles, and later at duty-status changes or after 3 hours or 150 miles, whichever occurs first

Federal regulations require the driver to confirm that cargo is properly distributed and secured before driving. The cargo and securement must be reinspected within the first 50 miles and when duty status changes or after three hours or 150 miles, whichever comes first. Limited exceptions apply to sealed loads and cargo that is impracticable to inspect.

Question 6

Which condition is a suspension-system defect?

  1. A A leaking shock absorber
  2. B An underinflated tire
  3. C A loose wheel lug nut
  4. D A cracked brake cylinder

Correct answer: A – A leaking shock absorber

The Wisconsin CDL manual lists leaking shock absorbers among the suspension defects a driver should look for during an inspection. Tires and lug nuts are wheel or tire inspection items, while a brake cylinder belongs to the braking system. Suspension components support the vehicle and keep its axles properly positioned.
