Driving Tank Vehicles — CDL Tank Vehicles Tiếng Việt

What do the baffles in a baffled tank help control?

📚 CDL Manual — Tank Vehicles (§8)

Questions are based on Section 8 (Tank Vehicles) of the official CDL manual (AAMVA model). The Tank Vehicles (N) endorsement is a knowledge test only and is given in ENGLISH (real test); our Chinese & Spanish are study aids to help you learn the English material. The N endorsement is required to haul a liquid or gas in a permanent/temporary tank over 119 gallons (or a portable tank of 1,000 gal+). Federal rules (FMCSA, 49 CFR 391.11) require English proficiency to drive commercially.
