At pickup, a hazardous-material package visibly leaks its contents, with no authorized venting or other exception. What should the driver do?
Correct answer: Refuse it and have the problem resolved before transport.
Without an authorized exception, visible release during normal transportation does not meet the package requirements. Refuse the leaking package and have its condition properly resolved before transport.

Hazardous-material packages are not permanently attached to the vehicle. What must their securement prevent during normal transportation?
Correct answer: Shifting, including movement relative to other packages.
Packages must be secured against normal transit movement. Loading must also minimize the chance of damage to valves and fittings.

Before loading or unloading hazardous material, what must be done to prevent the vehicle from moving?
Correct answer: Securely set the parking brake and take other reasonable precautions.
Set the parking brake securely and take other reasonable precautions to prevent movement. Neither apparently level ground nor transmission position replaces the required brake application.

An ordinary hazardous-liquid cargo tank still contains product. One manhole is unsecured. May it be driven a short distance to the exit?
Correct answer: No; secure the manhole before moving the tank.
The cargo-tank rule requires manhole closures closed and secured regardless of the quantity carried, subject to its stated empty-tank exception. A short distance is not itself an exception.

A truck containing Division 1.2 material is parked four feet from the traveled part of a public highway. Is this allowed under the parking rule?
Correct answer: No; it cannot be parked on or within five feet.
For a vehicle containing Division 1.1, 1.2 or 1.3 material, the parking rule prohibits parking on or within five feet of the traveled portion of a public street or highway. Four feet is inside that prohibited zone.

A driver of a placarded Class 3 vehicle wants to park within five feet of the traveled roadway for personal shopping. Does the brief operational-necessity exception cover that stop?
Correct answer: No; personal shopping is not the stated operational necessity.
The exception requires a brief operational necessity and impracticability of parking elsewhere. It does not provide a general convenience-parking exemption.

A Division 1.1 vehicle is to be parked 200 feet from a dwelling, with no qualifying operational necessity. Is that within the prohibited zone?
Correct answer: Yes; the rule uses 300 feet in these circumstances.
The rule restricts parking within 300 feet of bridges, tunnels, dwellings and places where people work or assemble, with a narrowly stated brief operational exception.

A truck containing covered hazardous materials stops to refuel its own fuel tank. What does the hazmat fueling rule require?
Correct answer: Engine off, with a person controlling the fueling at the fill point.
397.15 concerns fueling the motor vehicle itself. It requires the engine not to operate and a person to control the fueling process where the fuel tank is filled.

Before offering hazardous material in a package, who must ensure the package materials are compatible with its contents?
Correct answer: The offeror, as required by the packaging compatibility rule.
The offeror must ensure that the packaging is compatible with the hazardous material. A correct label or intact exterior does not by itself establish that the contents and packaging materials are compatible.

A closed hazardous-material package has hazardous residue adhering to its outside. Does a tight closure alone make this acceptable for ordinary transport?
Correct answer: No; the general packaging rule also prohibits hazardous residue outside.
General packaging requirements include no hazardous-material residue adhering to the package exterior during transport. Preventing leakage through the closure does not excuse contamination already outside.

When does the tire rule for covered hazardous-material vehicles require examination of each tire?
Correct answer: At the start of each trip and each time the vehicle is parked.
397.17(a) specifies trip-start and each-parking examinations. It does not replace the driver's other inspection duties.

A transportation incident meets 171.15's NRC telephone-report criteria. When must the person in physical possession notify the NRC?
Correct answer: As soon as practical, no later than 12 hours after occurrence.
The telephone deadline is as soon as practical and within 12 hours. This is not permission to delay emergency assistance; the detailed written report has a separate deadline.

A hazardous-material incident closes an interstate on-ramp for exactly one hour while the main lanes stay open. Does that meet the road-closure reporting trigger?
Correct answer: Yes; the one-hour-or-more rule includes access ramps.
PHMSA treats highway access ramps as parts of a major transportation artery. Closure for one hour or more can trigger NRC notice; exactly one hour qualifies, even when the main lanes remain open.

After filing a required detailed hazardous-material incident report, how long must the reporting person retain a copy?
Correct answer: Two years, with the required access for an authorized DOT request.
The rule requires retaining a copy for two years at the principal place of business. If stored elsewhere, it must be made available there within 24 hours of an authorized DOT request. Filing does not remove the retention obligation.

After delivery is complete and the carrier has left, the consignee unloads and spills material. Which reporting statement is correct?
Correct answer: HMR transportation reporting need not apply; other reporting laws may.
PHMSA distinguishes unloading after transportation ends. Environmental and other reporting obligations can still apply.

During hazardous-material loading into a cargo tank, may the responsible person leave the operation without any qualified attendance?
Correct answer: No; qualified attendance is required throughout loading.
The person responsible for loading must ensure qualified attendance throughout the process. This does not mean that unapproved remote observation or leaving equipment running unattended is acceptable.

A carrier has fulfilled its transport obligation and placed the cargo tank on the consignee premises, but the tractor remains there. Has the three-condition unloading-attendance release in 177.834(i)(2) been met?
Correct answer: No; motive power must also be removed from the tank and from the premises.
All three conditions must be met: the transport obligation fulfilled, the tank on the consignee premises, and motive power removed from both the tank and the premises. Mere arrival or engine shutdown is insufficient.

A qualifying remote-monitoring system was used to load a cargo tank. What check must a qualified person personally perform before departure?
Correct answer: A visual inspection for damage that may have occurred during loading.
The remote-monitoring alternative still requires a qualified person to inspect each loaded cargo-tank vehicle personally for loading damage before it leaves. Remote observation does not remove that departure check.
