The FMCSA revises its regulations concerning protection against shifting and falling cargo for commercial motor vehicles (CMVs) engaged in interstate commerce. The new cargo securement standards are based on the North American Cargo Securement Standard Model Regulations, reflecting the results of a multi-year comprehensive research program to evaluate current U.S. and Canadian cargo securement regulations; the motor carrier industry’s best practices; and recommendations presented during a series of public meetings involving U.S. and Canadian industry experts, Federal, State and Provincial enforcement officials, and other interested parties. The new rules require motor carriers to change the way they use cargo securement devices to prevent articles from shifting on or within, or falling from, CMVs. In some instances, the changes may require motor carriers to increase the number of tiedowns used to secure certain types of cargoes. However, the rule generally does not prohibit the use of tiedowns or cargo securement devices currently in use. Therefore, motor carriers are not required to purchase new cargo securement equipment to comply with the rule. The intent of this rulemaking is to reduce the number of accidents caused by cargo shifting on or within, or falling from, CMVs operating in interstate commerce, and to harmonize to the greatest extent practicable U.S., Canadian, and Mexican cargo securement regulations.
