Regulations and Compliance Flashcards

A driver has been on duty (not driving) for 3 hours, then drives for 8 hours, takes a 30-minute break, then drives 1 more hour. A shipper requests an additional 2-hour delivery run immediately after. Under FMCSA HOS rules, which regulation specifically prevents this?

Answer: The 11-hour driving limit — the driver has reached 9 hours of driving and needs a 10-hour off-duty reset before any further driving

The driver has accumulated 9 hours of driving (8 + 1). The FMCSA 11-hour driving limit means only 2 hours of driving remain. However, the shipper is requesting a 2-hour run — which would exactly hit the 11-hour cap — but the 30-minute break only satisfies the break requirement after 8 cumulative hours of driving, not a full reset. The driver cannot exceed 11 hours of driving in a 24-hour period, and with 9 hours used, a 2-hour run is technically within limits. The actual binding constraint here is that the 14-hour window (3 on-duty + 8 driving + 0.5 break + 1 driving = 12.5 hours elapsed) leaves less than 2 hours before the window closes — making the 14-hour window the real blocker. Wait — re-evaluating: 3 on-duty + 8 driving + 0.5 break + 1 driving = 12.5 hours on the 14-hour clock. A 2-hour run would push to 14.5 hours — exceeding the 14-hour rule. Answer A is correct.

Under 49 CFR Part 391, a motor carrier discovers that a newly hired CDL driver's medical certificate expired 8 days ago. The driver has already made two interstate runs this week. What is the dispatcher's immediate compliance obligation?

Answer: Remove the driver from all interstate service immediately; the driver is legally disqualified and every mile driven was an undetected violation

Under 49 CFR §391.41, a driver must have a valid medical examiner's certificate to operate a CMV in interstate commerce. An expired certificate means the driver is medically disqualified — there is no FMCSA grace period or extension mechanism available to carriers. The dispatcher must immediately pull the driver from service. The prior runs constitute violations the carrier must document and may need to self-report depending on audit context. Intrastate reassignment does not cure the federal disqualification, and no DVIR process addresses medical certificate lapses.

A flatbed carrier hauls a load of steel coils weighing 78,000 lbs gross vehicle weight. At a weigh station, the axle weight inspection reveals the drive axles are at 34,200 lbs. The legal limit is 34,000 lbs per tandem axle group. The driver calls dispatch. Which action is the dispatcher legally and operationally correct to recommend?

Answer: Instruct the driver to shift cargo rearward to transfer weight from the drive axles to the trailer axles, then request a reweigh

The correct action is to adjust the load distribution. On flatbed loads, coil placement can often be shifted to move weight off the drive axles onto the trailer's rear axles. After redistribution, the driver requests a reweigh. There is no universal 0.5% enforcement tolerance — enforcement tolerance varies by state and is at the officer's discretion, not a legal safe harbor. Overweight permits are obtained in advance, not at a weigh station counter for standard loads. State scale laws apply to all public roads, not just interstates.

A broker books a hazmat shipment of Class 3 flammable liquids (UN1993) and tenders it to a carrier. The carrier's dispatcher realizes the driver holds a CDL with a Hazardous Materials endorsement, but the carrier's operating authority does not include hazmat on its MC registration. What is the correct course of action?

Answer: Refuse the load; the carrier must have hazmat listed on its operating authority and maintain a current hazmat registration with FMCSA before tendering hazmat freight

Under 49 CFR Part 385 and the Hazardous Materials Regulations, a motor carrier transporting hazmat must have hazmat authority registered with FMCSA (shown on its operating authority) and must maintain a current hazmat registration (and pay the required fee) under 49 CFR Part 107, Subpart G. A driver's CDL-H endorsement qualifies the individual to operate the vehicle but does not substitute for the carrier's corporate-level hazmat registration. Tendering this load exposes both the carrier and broker to significant penalties under PHMSA and FMCSA regulations.

A dispatcher at a trucking company receives a request from a shipper to back-date a Bill of Lading to make a shipment appear to have departed two days earlier than it actually did, in order to meet a contractual delivery window. The shipper offers a $500 bonus. Under federal law, what is the most precise characterization of this act?

Answer: It constitutes falsification of a shipping document and may constitute mail or wire fraud under 18 U.S.C. §§ 1341/1343 if transmitted electronically or by mail, exposing the dispatcher and carrier to federal criminal liability

Back-dating a Bill of Lading to misrepresent shipment dates is falsification of a commercial document. When that document is transmitted electronically (email, EDI, TMS) or by mail, it satisfies the elements of mail fraud (18 U.S.C. §1341) or wire fraud (18 U.S.C. §1343), both federal felonies. The dispatcher who authorizes or executes this act faces personal criminal exposure, not just civil liability. No provision of 49 CFR Part 373 (freight bills) permits retroactive date falsification. The ICC was abolished in 1995 and no longer regulates trucking tariffs.

Under the FMCSA's Drug and Alcohol Clearinghouse (49 CFR Part 382, Subpart G), a carrier hires a CDL driver who was previously employed by another carrier. The driver's Clearinghouse record shows a drug violation from 14 months ago with a Return-to-Duty (RTD) test recorded but no negative follow-up test results yet logged. What must the dispatcher's carrier do before allowing this driver to operate a CMV?

Answer: The carrier must conduct a full query of the Clearinghouse, confirm the driver has completed the SAP's follow-up testing program (including all required follow-up tests), and may not use the driver until the SAP's program is complete and documented in the Clearinghouse

Under 49 CFR §382.703 and the Clearinghouse rules, a driver with a drug/alcohol violation is prohibited from performing safety-sensitive functions until they have: (1) completed the SAP evaluation, (2) passed an RTD test, and (3) completed all follow-up tests as prescribed by the SAP (which can include up to 6 tests in the first 12 months). An RTD test alone does not clear the driver — the full follow-up testing plan must be completed. The new employer inherits the obligation to verify Clearinghouse status via a full query and may not dispatch the driver until the SAP program is fully satisfied and documented. Follow-up testing responsibility transfers to the new employer under §382.605.
