To get a Tank Vehicles (N) endorsement for your CDL (Commercial Driver’s License), you must pass a 20-question knowledge exam on the safe operation of tankers. Your knowledge of liquid cargo handling, tanker vehicle safety practices, and commercial driving regulations will be evaluated at an DMV office, where you’ll take the official Tank Vehicles Knowledge exam. To prepare for this exam, you should read the official Commercial Driver’s License Manual (Arkansas CDL Handbook 2026), specifically Section 8 (Tank Vehicles).
