CDL Combination Vehicles TestInspecting Combination VehiclesMedium
When inspecting the cargo in a combination vehicle before a trip, you notice that the cargo in the rear of the trailer is not secured tightly against the front bulkhead and appears to have shifted slightly during previous movements. What is the primary concern and required action?
- AViolation of weight distribution regulations; redistribute cargo evenly.
- BRisk of cargo shifting further, impacting vehicle stability and braking; re-secure cargo immediately.
- CIncreased fuel consumption due to improper weight distribution; adjust tire pressure.
- DPotential for minor cosmetic damage to the cargo; continue with caution.
Show answer & explanationAnswer & explanation
Correct answer: B. Risk of cargo shifting further, impacting vehicle stability and braking; re-secure cargo immediately.
Shifting cargo is a significant safety hazard. It can drastically alter the vehicle's center of gravity, affecting stability, steering, and braking, and can lead to damage to the trailer or other vehicles. The cargo must be properly secured before departure.
Why the other options are wrong
- A. While weight distribution is important, the immediate issue here is the lack of securement, not necessarily a violation of weight limits (though it could contribute).
- C. While weight distribution affects fuel, the immediate and primary concern for shifting cargo is safety, not just fuel consumption.
- D. The primary concern is safety, not just cosmetic damage.
Cargo Securement Principles
Proper cargo securement prevents movement during transit, ensuring vehicle stability, preventing damage to cargo, and protecting other road users.
- Cargo must be contained, immobilized, or secured.
- Use appropriate tie-downs, dunnage, and bracing.
- Check securement before, during, and after trips.
- Federal regulations (FMCSA) dictate securement standards.
Memory trick: Loose cargo makes for a loose driver.
