Your trailer carries 1,200 lbs of Class 3 Flammable Liquid and 900 lbs of Class 8 Corrosive material — 2,100 lbs of hazmat total. Neither is a Table 1 material, and neither individually reaches 2,205 lbs. Which placarding option is permitted?
Hazmat (H) Endorsement • Free CDL Practice Question
Regulation
49 CFR 172.504 (DANGEROUS placard option); AAMVA CDL Manual Sec. 9.3.11 (nhcdm.pdf p.9-8)
Why This Matters
The DANGEROUS placard exists to simplify placarding for mixed, moderate-hazard loads, but it is only legal within specific weight limits per category. Misunderstanding it as a free substitute for any mixed load, regardless of weight, is a real citation risk.
