Safety Recommendation History
From: NTSB
Date: 7/1/2019
Response: We are encouraged by your efforts to identify new drug-impaired-driving countermeasures, examine the feasibility of a standardized field sobriety test for marijuana, update the relevant fact sheets, and improve drug-impaired driving reporting in the Fatality Analysis Reporting System. These efforts show progress toward addressing this recommendation. Pending your completion and our review of the recommended guidance, Safety Recommendation H-18-57 is classified OPEN--ACCEPTABLE RESPONSE.

Date: 4/18/2019
Response: -From Jonathan Morrison, Chief Counsel: NHTSA's Countermeasures That Work: A Highway Safety Countermeasure Guide for State Highway Safety Offices: Ninth Edition, 2017 points out that the most effective countermeasure to drug-impaired driving is law enforcement. NHTSA continues to support effective and efficient training methods for law enforcement personnel, including Drug Recognition Experts. NHTSA has a study underway on the current state of knowledge on drug-impaired driving, which may identify new countermeasures. We expect this study to conclude in late 2019. Another project underway, to be completed in 2020, will examine the feasibility of a Standardized Field Sobriety Test (SFST) for marijuana. If effectiveness is demonstrated, SFST for marijuana will be added to the next edition of Countermeasures that Work. We are also in the process of updating our Drugs and Human Performance Fact Sheets, with publication expected in 2020. A challenge with drug-impaired driving is the lack of valid and reliable data on the scope and magnitude of the problem. NHTSA is working on improvements in the reporting of drug-impaired driving fatal crash data in our FARS data system, and this will be an ongoing effort. NHTSA also has developed messaging and a new public service campaign to inform the public on the dangers of drug impaired driving. NHTSA requests this recommendation be classified as Open, Acceptable Response.
