The shippers package hazardous materials, they must certify that this was done according to the regulations. The only exception is when:
- The driver is given a sealed cargo compartment
- The shipper is a private carrier carrying his or her own product
- The shipment is a hazardous waste
When companies send out dangerous goods, they must follow rules to pack them safely. The only time they don't have to is if the company is moving its own products and not selling the service.
How many hazard classes are there?
- 3
- 9
- 10
There are 9 different types of dangers or hazard classes that truck drivers need to know about when they are carrying goods. These classes help them understand what kind of special care or rules they need to follow to keep the roads safe.
Apart from the shipping papers and the packages, what other two locations must display the hazardous material identification number?
- on the front bumper and on the inside of the cab door.
- on the exhaust system and on a decal on the dashboard.
- on the driver’s door and on the steering column.
- on all bulk packaging and on the cargo tanks.
Beyond shipping papers and packages, the hazardous material identification number is also required to be shown on cargo tanks and on all bulk packaging.
A driver places placards on their vehicle in order to:
- to show the vehicle’s maximum legal weight.
- to advertise the company hauling the load.
- to communicate risk.
- to indicate the driver’s route and destination.
Placards are exterior signs on a vehicle that alert others to the presence of hazardous materials and indicate the hazard class of the load.
Why is the shipper required to sign the shipping paper?
- To confirm the carrier has inspected and approved the shipment for transport
- To certify that it has prepared the shipment in accordance with regulations
- To confirm the carrier has received payment for transporting the shipment
The shipping paper has to contain the shipper’s certification, signed by the shipper, confirming the shipment was prepared in compliance with the applicable regulations.
Carriers must provide each driver who hauls Division 1.1, 1.2, or 1.3 materials with:
- a written list of emergency response phone numbers for local fire departments.
- a copy of FMCSR Part 397.
- a copy of the shipper’s facility address and receiving hours.
Carriers are required to give drivers transporting explosives a copy of 49 CFR 397, “Transportation of Hazardous Materials; Driving and Parking Rules.” This part includes rules on hazardous materials routing, including factors to consider when selecting an appropriate route.
Hazardous material identification numbers must be shown on portable tanks, cargo tanks, and other bulk packages. Regulations require black ______ numbers.
- 75 mm
- 125 mm
- 100 mm
Hazardous material identification numbers must appear on portable tanks, cargo tanks, and other bulk packaging. The rules specify black 100 mm (3.9 inch) numbers on orange panels, placards, or on a white diamond-shaped background when placards are not required.
Helium is classified as a Class ____ hazardous material.
- 2
- 9
- 1
A hazardous material’s class indicates the type of risk it presents. There are nine hazard classes in total. Class 2 covers gases, including flammable gases (2.1) like propane, non-flammable gases (2.2) like helium, and toxic gases (2.3) such as compressed fluorine.
Who must select the safest route when transporting placarded radioactive materials?
- The state highway department
- The receiver/consignee
- The carrier
If placarded radioactive materials have to be transported, the carrier is responsible for choosing the safest route. Once the route is selected, the carrier must inform the driver about the radioactive materials and provide the driver with the planned route.
With most hazardous materials, you may park within 5 feet of the road briefly. If your work requires it. The materials that are the exception and do not allow parking this close to the road are?
- Acids and poisons
- Corrosives and oxidizers
- Explosives 1.1 thru 1.3
When it comes to parking near the road with hazardous materials, you usually can if it's quick and needed for work. But, don't do this with very explosive materials (like fireworks or dynamite), flammable stuff (like gasoline or propane), because it's too dangerous.
A truck as hazardous material, when can it be moved without the placards on the truck?
- Never
- When the shipper says it's ok
- To protect life or property
If a truck is carrying dangerous materials, it usually must have special signs (placards) on it to show that it is hazardous. However, there is one exception to this rule. The truck can be moved without these signs only if it is necessary to protect people's lives or to prevent property from being damaged. This means safety is the top priority, and in an emergency situation, the truck can be moved even without the placards.
Which option lists a required criterion for a package to qualify as non-bulk packaging?
- A water capacity of 454 kg (1,000 pounds) or less if it is used as a receptacle for a gas
- A maximum net mass of 400 kg (882 pounds) or less and a maximum capacity of 450 L (119 gallons) or less if it is used as a receptacle for a solid
- A maximum capacity of 450 L (119 gallons) or less if it is used as a receptacle for a liquid
- All of the above
Non-bulk packaging must meet defined limits when used as a container for solids, liquids, or gases. It qualifies as non-bulk if it is: 450 L (119 gallons) or less for liquids; 400 kg (882 pounds) or less and 450 L (119 gallons) or less for solids; and 454 kg (1,000 pounds) or less for gases.
If you are transporting Division 1.2 or 1.3 materials, what is the minimum distance you must park from a bridge, tunnel, or building?
- 300 feet
- 150 feet
- 250 feet
- 50 feet
With a load of Division 1.2 or 1.3 explosives, you are required to park no closer than 300 feet from any bridge, tunnel, or other structure.
Under what circumstances may a shipper shorten (abbreviate) the proper shipping name or hazardous material identification number on a shipping paper?
- Only if regulations specifically authorize the shipper to do it
- Only when the shipment is moving by highway within the same state
- Only when the material is non-flammable and low hazard
A shipper is not allowed to abbreviate a hazardous material’s identification number, hazard class, or proper shipping name unless the regulations explicitly permit that abbreviation. Abbreviations can interfere with correct identification and create safety risks.
You must stop before a railroad crossing if your vehicle is transporting _______ of chlorine.
- at least 100 gallons
- any amount
- more than 110 gallons
If you are transporting any quantity of chlorine gas, you are required to stop at every railroad crossing and use extra caution before crossing. A train collision could cause a chlorine release, which is very dangerous because chlorine gas is poisonous. (If chlorine is being hauled in cargo tanks, a gas mask must be available in the cab.) Chlorine is also a strong oxidizer and can react with flammables to start fires, which may spread corrosive or toxic gases.
You may allow another person to watch your vehicle only when it is…
- parked at a public rest area while you take a break.
- being watched by any licensed driver.
- on the property of the shipper, carrier, or receiver.
You may let someone else watch your vehicle only when you are on the property of the shipper, carrier, or consignee/receiver, since those parties understand the hazards and how to handle them.
Which hazard class covers both flammable gases and non-flammable gases?
- 2
- 4
- 9
A material’s hazard class indicates the type of risk it presents. There are nine hazard classes. Hazard Class 2 is for gases, including flammable gases (2.1) like propane, non-flammable gases (2.2) like helium, and toxic gases (2.3) such as compressed fluorine.
If you think there may be a cargo fire in your trailer and the cargo doors feel hot, what should you do?
- crack the doors slightly to let heat and smoke escape.
- leave the doors closed.
- swing the doors fully open to ventilate the trailer.
Hot cargo doors make it more likely a fire is burning inside. Opening the doors would add oxygen and can intensify the fire. Keeping the doors shut limits oxygen, so the fire may only smolder until firefighters arrive.
By law, how regularly must employees involved in transporting hazardous materials be tested?
- Within 90 days of hire and then every 3 years
- Within 90 days of hire and then every 6 months
- At least every 5 years
People who transport dangerous stuff must be tested within 90 days of starting their job and then every 3 years to make sure they know how to handle these materials safely.
Symbol column, the letter "G" stands for?
- Identifies the proper shipping name for which one or more technical names of the hazardous material must be entered in parentheses, along with the basic description
- Identifies the proper shipping name
- Gases
The letter "G" means you need to write the hazardous material's specific name next to its general name when shipping it.

About the HazMat Test in Georgia
The HazMat endorsement test is required in Georgia for drivers who transport hazardous materials. It covers placarding, labeling, loading procedures, emergency response, and compliance with federal hazmat regulations. A TSA background check is also required.
The HazMat test is part of the CDL written exam administered by the Georgia Department of Motor Vehicles. You must pass this test along with the other required written tests to receive your Commercial Learner's Permit (CLP) in Georgia.
Our practice questions are built from the official Georgia CDL handbook and federal FMCSA regulations. Each question includes a detailed explanation to help you understand the material, not just memorize answers.

How to add the HazMat endorsement in Georgia
- Already hold a full Georgia CDL (or be ready to hold one) — Georgia’s own endorsement table marks the H (Hazardous Materials) endorsement as not allowed on a permit. Source
- Apply through TSA’s Universal Enroll program and get fingerprinted at a TSA-approved Georgia location. Source
- Wait for the TSA security threat assessment and fingerprint-based background check — DDS says this takes approximately 60–90 days, and the endorsement cannot be added until TSA’s result reaches DDS. Source
- Pass the hazardous-materials knowledge test at a DDS Customer Service Center (80% correct, like every Georgia knowledge test). Source
- Once added, the Hazmat endorsement is valid for 5 years from your TSA Threat Assessment date, and renewing it repeats the TSA background check and fingerprints — it is also the one endorsement that does NOT transfer automatically when you move your CDL from another state. Source

Georgia CDL questions
- What score do I need on Georgia’s CDL knowledge tests, and what if I fail?
- Every Georgia CDL knowledge test needs 80% correct. If you fail, the wait to retest is two days — the same wait applies to the first failure and every one after it. Source
- What does Georgia require for a Hazmat (H) endorsement?
- You cannot add H to a permit — you need a full CDL first. Apply through TSA’s Universal Enroll, get fingerprinted, and wait roughly 60–90 days for the TSA background check and threat assessment. Then pass the hazmat knowledge test (80%) at a DDS Customer Service Center. Once issued, the endorsement is valid 5 years from your TSA Threat Assessment date, and it is the one endorsement that will NOT transfer automatically if you move your CDL from another state. Source
- How much does Georgia’s Hazmat endorsement cost?
- Nothing extra if you add it at the same time as your initial CDL — Georgia’s renewal page says plainly that no fee applies then. Added later, it costs a one-time $5, the same as the state’s other endorsements. On top of that you pay TSA directly for the federally required background check and threat assessment ($85.25, or $41 with a valid TWIC). Renewing the endorsement itself needs a fresh Hazmat knowledge test and a fresh TSA background check every 5 years — it does not renew automatically with the rest of your CDL the way other endorsements do.
