Regulations and Compliance Flashcards

A carrier operating under a lease agreement receives a citation for an HOS violation committed by a leased owner-operator. Under 49 CFR Part 376, who bears primary regulatory responsibility for the violation?

Answer: The authorized carrier whose operating authority the owner-operator was dispatched under

Under 49 CFR Part 376 (Lease and Interchange of Vehicles), when an owner-operator is leased to an authorized carrier, the carrier assumes full regulatory responsibility for the operation of that vehicle during the lease period, including HOS compliance. The carrier's name and operating authority must appear on the vehicle, and the carrier is the entity the FMCSA holds accountable.

A driver transporting a load of consumer fireworks (UN 0336, Division 1.4G) requests dispatch through a tunnel in a major city. Under the Hazardous Materials Regulations (49 CFR Part 397), which statement is most accurate regarding tunnel routing?

Answer: The carrier must consult state and local tunnel authority restrictions, which may prohibit or restrict passage even for 1.4G materials

While 49 CFR 397.9 establishes federal routing rules for hazardous materials, it explicitly preserves state and local authority to restrict or prohibit tunnel passage for explosive materials, including Division 1.4. Many major tunnels prohibit all explosive divisions. Dispatchers must check tunnel-specific authority rules — federal preemption does not override local tunnel restrictions for explosives.

A dispatcher is planning a trip for a driver who is currently in the 60-hour/7-day cycle. The driver has 8 hours remaining. The planned trip requires 10 hours of driving. Which regulatory provision, if applicable, would legally allow the driver to complete this trip without taking a 34-hour restart?

Answer: There is no provision — the driver must go off-duty until enough hours free up via the rolling 7-day calculation

The 60-hour/7-day (or 70-hour/8-day) limit is a cumulative cap on on-duty time within a rolling window. None of the standard exceptions — not the 16-hour short-haul exception, not the adverse conditions extension, and not the short-haul exemption — add hours to the weekly cycle limit. Only a 34-hour restart or waiting for older on-duty hours to drop off the rolling 7-day window can legally free up enough hours. The dispatcher must restructure the load or wait.

Under 49 CFR Part 382 (FMCSA Drug & Alcohol Testing), a dispatcher is notified that a CDL driver has just been involved in a non-fatal accident where a vehicle was towed from the scene but no citations were issued. What is the correct post-accident testing obligation?

Answer: Alcohol testing is required within 8 hours; drug testing within 32 hours — citation issuance is irrelevant when a vehicle is towed

Under 49 CFR 382.303, post-accident testing is triggered by specific criteria — one of which is a vehicle being towed from the scene, regardless of whether a citation was issued. When a CMV is involved in an accident where any vehicle requires towing, alcohol testing must occur within 8 hours and drug testing within 32 hours. Citation issuance is only relevant to the third criterion (bodily injury with immediate medical treatment); it does not apply to the tow-away scenario.

A freight broker dispatches a load to a carrier that is later found to have had its operating authority revoked two days prior to the load being tendered. Under FMCSA regulations, what is the broker's potential liability exposure?

Answer: The broker may face FMCSA civil penalties and shipper claims for failing to verify active authority at the time of load tender

Under 49 CFR Part 371 and FMCSA guidance, brokers have an ongoing duty of reasonable care in selecting carriers, which includes verifying active operating authority at or near the time of load tender — not merely at initial setup. Brokering freight to a carrier with revoked authority exposes the broker to civil penalties from the FMCSA and potential negligent selection claims from shippers or cargo claimants. Real-time SAFER/L&I verification is considered industry standard practice.

A dispatcher is planning a multi-state oversize/overweight (OS/OW) move for a load that is 14 feet wide. One state en route requires a sealed permit with a specific escort configuration and mandatory travel hours. The driver calls mid-trip to report the escort vehicle has broken down. What is the legally correct action?

Answer: The driver must immediately stop movement and remain stationary until the required escort configuration is restored or the state permit office authorizes an alternative

OS/OW permits are issued with specific conditions — including escort requirements — that are legally binding. If a mandatory escort vehicle becomes unavailable mid-trip, the permitted move is no longer in compliance with the permit terms. The load must stop until full compliance is restored or the issuing state permit authority grants an amendment or exception. No federal or state provision allows a dispatcher or driver to unilaterally waive escort requirements; continuing movement would constitute a permit violation subject to fines and potential permit revocation.
