How must hazardous-material packages be secured inside a vehicle?
Correct answer: C – Secured against shifting during transportation
The Minnesota CDL manual teaches that hazardous-material containers must be braced to prevent movement. Federal regulations require packages that are not permanently attached to the vehicle to be secured against shifting, including relative movement between packages. Packages with valves or fittings must also be positioned to minimize the likelihood of damage.
