The Hazardous Materials (H) endorsement exam is widely considered the most difficult written test in the trucking industry. Unlike General Knowledge, you cannot rely on common sense. You must memorize specific federal regulations found in 49 CFR Parts 171-180.
You must know how to package, load, and secure hazardous products so they do not leak or escape during transit.
This is the #1 tested topic. You must use Shipping Papers and Placards to tell emergency responders exactly what is in your trailer.
This is where 50% of students fail. You must know the difference between Table 1 and Table 2 materials.
