TRIP Transportation Operations & Safety 2 — Questions and Answers
Question 1: What is the primary regulatory purpose of the FMCSA's Electronic Logging Device (ELD) mandate?
- To track vehicle fuel consumption and emissions
- To automatically record a commercial driver's hours of service (Correct answer)
- To monitor cargo weight distribution in real time
- To schedule and document preventive vehicle maintenance
Correct answer: To automatically record a commercial driver's hours of service
The ELD mandate requires devices that automatically record driving time, replacing paper logbooks to improve hours-of-service compliance and reduce fatigue-related crashes.
Question 2: Under FMCSA drug and alcohol regulations, a commercial driver is prohibited from operating a CMV if their blood alcohol concentration (BAC) is at or above:
- 0.02%
- 0.04% (Correct answer)
- 0.08%
- 0.10%
Correct answer: 0.04%
FMCSA sets a 0.04% BAC threshold for commercial drivers—half the standard 0.08% limit—reflecting the higher public safety responsibility of CMV operators.
Question 3: Which sections of Title 49 CFR contain the Hazardous Materials Regulations (HMR) governing transportation of dangerous goods by motor carrier?
- Parts 171–180 (Correct answer)
- Parts 382–395
- Parts 390–396
- Parts 400–410
Correct answer: Parts 171–180
The HMR are codified in 49 CFR Parts 171–180 and cover hazmat classification, packaging, marking, labeling, placarding, and incident reporting requirements.
Question 4: What is the meaning of a 'Satisfactory' safety rating issued by the FMCSA following a compliance review?
- The highest rating, indicating the carrier has adequate safety management controls in compliance with regulations (Correct answer)
- A mid-level rating indicating minor violations that must be corrected within 90 days
- The lowest passing rating before a carrier receives a Conditional designation
- A provisional rating pending completion of a full investigation
Correct answer: The highest rating, indicating the carrier has adequate safety management controls in compliance with regulations
'Satisfactory' is the highest FMCSA safety rating, confirming that the carrier's safety management controls meet or exceed federal regulatory standards.
Question 5: In freight transportation, 'intermodal transportation' is best described as:
- The exclusive use of rail and truck for domestic freight
- Moving cargo in standardized containers across multiple transport modes without unloading the goods (Correct answer)
- Air freight combined exclusively with ocean shipping for international trade
- Transportation limited to shipments crossing international borders
Correct answer: Moving cargo in standardized containers across multiple transport modes without unloading the goods
Intermodal transportation uses standardized containers that transfer seamlessly among truck, rail, and ocean vessels, reducing handling costs and transit time.
Question 6: What is the maximum gross vehicle weight allowed for a standard five-axle tractor-trailer combination on U.S. federal interstate highways?
- 72,000 pounds
- 78,000 pounds
- 80,000 pounds (Correct answer)
- 85,000 pounds
Correct answer: 80,000 pounds
The federal Bridge Formula and weight statutes set the maximum gross vehicle weight for a standard five-axle combination at 80,000 pounds on interstate highways.
Question 7: Within the CSA program, which tool does FMCSA use to prioritize motor carriers with the worst safety performance for interventions and investigations?
- New Entrant Safety Assurance Program
- Compliance Review Program
- Motor Carrier Safety Rating System
- Intervention Selection Model (ISM) (Correct answer)
Correct answer: Intervention Selection Model (ISM)
The ISM uses SMS BASIC percentile scores to rank carriers by safety risk and determine which ones should receive targeted FMCSA interventions, from warning letters to full investigations.
