Q1. Under 49 CFR 393 Subpart I, what is the fundamental
principle of cargo securement that all regulations are based
upon?
A) Cargo should be protected from weather
B) Cargo must be immovable under all foreseeable driving
conditions
C) Cargo must be loaded evenly on the trailer
D) Cargo must be covered with a tarp
✅ Answer: B) Cargo must be immovable under all
foreseeable driving conditions
🧠 Rationale: The fundamental principle of the North American
Cargo Securement Standard, adopted by FMCSA, is that cargo
must be secured so it cannot shift or fall from the vehicle under
,Page 2 of 205
all conditions of acceleration, deceleration, turning, and road
surface irregularities that a driver would reasonably encounter
during transit.
Q2. The FMCSA cargo securement regulations apply to which
vehicles operating in interstate commerce?
A) Only tractor-trailers with three axles
B) All commercial motor vehicles
C) Vehicles over 26,000 lbs only
D) Only flatbed trailers
✅ Answer: B) All commercial motor vehicles
🧠 Rationale: FMCSA cargo securement regulations (49 CFR Part
393, Subpart I, Sections 393.100 through 393.136) apply to all
commercial motor vehicles operating in interstate commerce. They
are not limited to a specific vehicle type or weight class.

Q3. According to the FMCSA, cargo must be secured to
withstand a forward deceleration force equivalent to what
percentage of its weight?
A) 50% (0.5g)
B) 80% (0.8g)
C) 100% (1.0g)
D) 20% (0.2g)
✅ Answer: B) 80% (0.8g)
🧠 Rationale: FMCSA quantifies the required forward restraint
as a deceleration force of 0.8g, meaning the securement system
must be able to withstand a force equal to 80% of the cargo
weight in the forward direction. Rearward and lateral forces are
lower at 0.5g (50% of cargo weight).

Q4. What is the minimum lateral restraint force required by
FMCSA for cargo securement systems?
A) 0.5g (50% of cargo weight)
B) 0.8g (80% of cargo weight)
C) 0.2g (20% of cargo weight)
D) 1.0g (100% of cargo weight)
✅ Answer: A) 0.5g (50% of cargo weight)
🧠 Rationale: Lateral restraint must withstand a force of 0.5g
(50% of cargo weight) to either side. This ensures the cargo does
not shift sideways during turning maneuvers or when the vehicle is
placed on a road with a significant crown.
Q5. The North American Cargo Securement Standard was
developed jointly by which countries?
