Sample Georgia CDL Tanker Test Practice Questions

Try these sample questions to test your Georgia CDL Tanker Test exam readiness. Each question includes a detailed explanation. Start the interactive quiz above for the full 300+ question experience with AI tutoring.

1When does Georgia Section 8 say a Class A or B CDL driver needs a tank vehicle endorsement?

A.Only for hazardous liquids

B.For liquid or gaseous material in tanks over 119 gallons each with 1,000 gallons or more aggregate capacity

C.Only for permanently mounted gasoline tanks

D.Only for tanks over 10,000 gallons

Explanation: Georgia Section 8 follows the federal tank vehicle definition for Class A and B CDL drivers. The liquid or gas does not have to be hazardous if the tank capacity thresholds are met.

2Which CDL endorsement code is used for tank vehicles?

A.H - hazardous materials

B.N - tank vehicles

C.P - passenger

D.T - double/triple trailers

Explanation: Georgia DDS and FMCSA use endorsement code N for tank vehicles. H is hazardous materials, P is passenger, and T is doubles/triples.

3What Georgia DDS test requirement is listed for adding the N Tanker Endorsement?

A.Knowledge test only

B.Skills test only

C.Knowledge and road tests

D.No test if the tank is empty

Explanation: Georgia DDS lists the N Tanker Endorsement as a knowledge-test-only endorsement. A separate tanker skills test is not listed for adding N.

4A Georgia driver wants both tank vehicle and hazardous materials privileges. Which endorsement combination is used?

A.N - tank vehicles only

B.H - hazardous materials only

C.X - tank vehicles and hazardous materials

D.T - double/triple trailers

Explanation: The X endorsement combines tank vehicle and hazardous materials authority. N alone is the tank vehicle endorsement and H alone is hazardous materials.

5Can non-hazardous liquid cargo require the N endorsement?

A.Yes, if the CDL class and tank capacity thresholds are met

B.No, only placarded hazardous materials count

C.Only if the liquid is flammable

D.Only if the route crosses state lines

Explanation: Georgia Section 8 states that the liquid or gas does not have to be hazardous. The endorsement issue depends on CDL class and tank capacity thresholds.

6Under FMCSA rules, how may a CLP holder with an N endorsement operate a tank vehicle?

A.Loaded with any liquid

B.Empty only, and not with unpurged hazardous-material residue

C.Only on private property

D.Only with passengers

Explanation: FMCSA limits CLP holders with an N endorsement to empty tank vehicles. A tank that previously held hazardous materials must be purged of residue before CLP operation.

7Which Georgia CDL manual section is titled Tank Vehicles?

A.Section 2

B.Section 5

C.Section 8

D.Section 13

Explanation: Georgia DDS Section 8 is the Tank Vehicles section. It is the primary source for Georgia tanker endorsement study.

8What minimum score is required on CDL knowledge tests under 49 CFR 383.135?

A.60 percent

B.70 percent

C.80 percent

D.90 percent

Explanation: 49 CFR 383.135 requires applicants to correctly answer at least 80 percent of the questions on each CDL knowledge test. Georgia CDL testing operates under these federal standards.

9What is the most important tank-specific item to check on every tank vehicle?

A.Leaks

B.Paint color

C.Radio reception

D.Seat adjustment

Explanation: Georgia Section 8 says leaks are the most important item to check on tank vehicles. A leaking tank may lead to citations, being stopped, and cleanup liability.

10What should you do if a tank body is leaking before the trip?

A.Drive slowly to the receiver

B.Do not carry liquid or gas in the leaking tank

C.Open the vents and continue

D.Add product to seal the leak

Explanation: Georgia Section 8 warns not to carry liquids or gases in a leaking tank. The leak must be corrected before the vehicle is operated.

About the Georgia CDL Tanker Test Exam

The Georgia CDL Tanker Vehicles Endorsement Test covers the knowledge needed to operate commercial motor vehicles transporting liquid or gaseous materials in qualifying tanks. Georgia DDS Section 8 emphasizes tank inspections, leaks, valves, hoses, manhole covers, vents, special equipment, high center of gravity, liquid surge, slippery-surface stopping risk, bulkheads, baffled tanks, smooth-bore tanks, outage/ullage, expansion, dense-liquid weight, and legal loading limits. DDS administers the knowledge test under FMCSA CDL standards, and federal rules require at least 80 percent correct on CDL knowledge tests.

Assessment

Multiple-choice CDL written knowledge exam for the N Tanker endorsement, covering Georgia CDL Manual Section 8 tank vehicles plus related driving-safety, air-brake, combination-vehicle, and hazardous-materials sections when applicable. 49 CFR 383.119 requires tanker applicants to know surge causes and effects, braking when empty/full/partially full, baffled and non-baffled handling, tank construction, product-density effects, grades and curves, emergency systems, retest/marking requirements for DOT specification tanks, and operating procedures.

Georgia CDL Tanker Test Study Tips from Top Performers

1Read Section 8 once for structure, then reread the subsections on inspection, high center of gravity, surge, bulkheads, baffles, unbaffled tanks, outage, and loading amount.

2Memorize the endorsement threshold: tanks over 119 gallons each and 1,000 gallons or more aggregate capacity for Class A/B CDL tank vehicle operation.

3Treat surge questions as handling questions: partial load, smooth inputs, extra following distance, early braking, and low curve speed.

4Separate baffles, bulkheads, and smooth-bore tanks; baffles reduce forward/back surge, bulkheads divide compartments, and smooth-bore tanks have the strongest surge.

5Do not overlook Georgia logistics: $10 permit/testing fee, $35 CAP fee, 14-day CLP hold before skills testing, 365-day CLP validity, and the federal 80 percent pass standard.
