Priority Open Recommendations: Department of Transportation
Dear Mr. Secretary:
The purpose of this letter is to provide an update on the overall status of the Department of
Transportation's (DOT) implementation of GAO's recommendations and to call your continued
personal attention to areas where open recommendations should be given high priority.' In
November 2023, we reported that, government-wide, 75 percent of our recommendations made
4 years ago were implemented.2 DOT's recommendation implementation rate was 76 percent.
As of April 2024, DOT had 212 open recommendations. Fully implementing these open
recommendations could significantly improve agency operations.
Since our May 2023 letter, DOT has implemented two of our 20 open priority
recommendations.3 Specifically:
* In coordination with the Department of Homeland Security, DOT analyzed the results of a
survey on the use of the National Institute of Standards and Technology (NIST)
cybersecurity framework. The analysis identified the usage, awareness, and implementation
1Priority recommendations are those that we believe warrant priority attention from heads of key departments or
agencies. They are highlighted because, upon implementation, they may significantly improve government
operations, for example, by realizing large dollar savings; eliminating mismanagement, fraud, and abuse; or making
progress toward addressing a high-risk or duplication issue.

2023).
31n addition, we removed the priority status from one recommendation to the Federal Motor Carrier Safety
Administration (FMCSA) regarding revisions to the Safety Measurement System (SMS) methodology since our May
2023 letter due to actions taken by Congress and DOT. At the time of our report, FMCSA publicly reported percentile
rankings of motor carriers based on imprecise SMS scores. Since that time, the FAST Act was enacted in 2015,
which, among other things, prohibited FMCSA from publicly reporting these percentiles for most motor carriers until
DOT's Inspector General makes certain certifications. In addition, FMCSA has taken several steps to determine how
it might revise its method to compare safety performance across motor carriers. Based on the actions taken, we no
longer believe this recommendation warrants priority attention. We continue to believe FMCSA should make a final
determination on implementation of a new methodology to fully address the recommendation. GAO, Federal Motor
Carrier Safety: Modifying the Compliance, Safety, Accountability Program Would Improve the Ability to Identify High
Risk Carriers, GAO-14-114 (Washington, D.C.: February 3, 2014).
