The document summarizes recent developments regarding hours of service regulations and the Compliance, Safety, Accountability (CSA) program in the mid-2013 timeframe. Regarding hours of service, the American Trucking Associations lawsuit challenging changes to the rules was largely unsuccessful, though the 30-minute break requirement was overturned for short-haul drivers. The CSA Advisory Subcommittee issued recommendations on how to improve the CSA program, including whether to include non-preventable crashes in scoring and whether to publicly display certain scores. Additionally, a lawsuit was filed challenging FMCSA guidance on the use of CSA data by shippers, brokers, and insurers.
