How many tiedowns are required for every feet of cargo to prevent shifting?

Answer: B — 10

For every 10 feet of cargo, a minimum of two tiedowns is required to prevent shifting. This establishes a clear guideline for safely securing cargo. The logic behind this requirement is based on the need to maintain stability during transit. If the cargo is longer, it increases the risk of shifting, which can result in dangerous driving conditions. Since the question specifically asks how many tiedowns are necessary for every foot of cargo, it can be interpreted as needing a tiedown for every 5 feet; thus, two tiedowns for each 10 feet. Therefore, if we consider the overall regulation for securing loads, the requirement effectively translates to a accurately way of securing loads to mitigate shifting during travel. Adhering to these standards is crucial for safe transportation, as unsecured cargo can lead to accidents, not only for the driver but also for others on the road. This requirement reflects the safety protocols in place to protect all road users.
