Nebraska CDL Practice Test

A Nebraska feed-hauling combination is rated at 29,200 pounds in total, and its trailer is rated at 12,400 pounds. Which CDL class covers it?

1. AClass A, because the combination is at least 26,001 pounds and the trailer exceeds 10,000 poundsCorrect
2. BClass B, because every agricultural trailer is treated as part of one straight vehicle
3. CClass C, because only the trailer rating matters when classifying a combination
4. DNo CDL class, because a combination must reach 40,001 pounds before classification

Why: Class A, because the combination is at least 26,001 pounds and the trailer exceeds 10,000 pounds best manages the described risk. Class A covers a combination rated at least 26,001 pounds when the towed vehicle or vehicles have a gross vehicle weight rating above 10,000 pounds.

A car looks small in the tractor's convex mirror as it approaches from the rear. What judgment should the driver make?

1. AThe car is probably closer than it appears, so the mirror check should be brief and interpreted cautiouslyCorrect
2. BThe car must be farther away than a flat mirror would show, so a lane change is immediately safe
3. CConvex mirrors show exact distance and make speed judgment unnecessary
4. DThe driver should stare at the mirror until the car disappears from forward vision

Why: The car is probably closer than it appears, so the mirror check should be brief and interpreted cautiously best manages the described risk. Mirror checks should be brief, and convex mirrors require judgment because they make objects appear smaller and farther away than they are.

A warehouse employee loads and seals a trailer before the driver arrives. Who remains responsible for making sure the cargo is properly secured for travel?

1. AThe driver remains responsible for the cargo's safe loading and securementCorrect
2. BOnly the warehouse employee, because a sealed trailer removes all driver responsibility
3. CThe first highway patrol officer who sees the vehicle
4. DThe consignee, but only after the trailer reaches its destination

Why: The driver remains responsible for the cargo's safe loading and securement best manages the described risk. Even when another person loads the vehicle, the driver remains responsible for inspection, overload and balance recognition, securement, clear visibility, and access to emergency equipment.

The prior bus driver left a vehicle-condition report before changing shifts. What must the incoming driver verify?

1. AEvery listed condition is automatically safe if the bus starts normally
2. BThe incoming driver needs only a verbal summary from a passenger
3. CAny listed defect was repaired or certified as not requiring repair, and the incoming driver signs the report when requiredCorrect
4. DThe report may be discarded unopened because only the prior driver can use it

Why: Any listed defect was repaired or certified as not requiring repair, and the incoming driver signs the report when required best manages the described risk. A bus driver signs the previous driver's inspection report only after listed defects have been certified as repaired or certified as not requiring repair.

A combination vehicle is being loaded with dense machine parts. Which placement helps it resist rollover?

1. ASuspend the weight above the trailer floor so it can swing
2. BConcentrate everything at the highest rear corner
3. CKeep the heavy material low and centered between the sidesCorrect
4. DStack the dense parts against the roof and one side

Why: Keep the heavy material low and centered between the sides best manages the described risk. Combination cargo should be kept low, centered, and distributed because a high or side-biased center of gravity increases rollover risk.

A hazmat driver finds a leaking package and shipping papers that do not support the offered load. What should the driver do?

1. ACover the leak with an unrelated label and omit it from the papers
2. BAccept any package chosen by the shipper because the driver has no hazmat responsibility
3. CReject the defective or undocumented shipment and accept only cargo that can be transported with correct papers, markings, and placardsCorrect
4. DLoad the leaking package first and correct the documents after delivery

Why: Reject the defective or undocumented shipment and accept only cargo that can be transported with correct papers, markings, and placards best manages the described risk. The hazardous-material driver rejects leaking or improperly prepared packages, maintains required placards and papers, and transports the shipment safely after shipper and carrier checks.
