As a result of the crash, the bus driver and 12 passengers were fatally injured. The driver of the truck and one bus passenger sustained serious injuries.

Safety Recommendation History
From: NTSB
Date: 7/1/2019
Response: We note that you are monitoring developments with these devices to determine future guidance needs. As we noted in our report, although some states have engaged in pilot programs to test the reliability of roadside oral fluid drug screening devices, widespread implementation of the equipment is unlikely without your support. In addition, we agree that law enforcement can use the devices without your guidance; however, federal leadership is important in this area and many states are waiting for your best practices and model specification guidance before using the devices. We encourage you to move forward with your development of the recommended guidance. Pending our receipt and review of the documents, Safety Recommendation H-18-56 is classified OPEN--ACCEPTABLE RESPONSE.

Date: 4/18/2019
Response: -From Jonathan Morrison, Chief Counsel: NHTSA believes oral fluid drug screening devices could assist law enforcement in establishing probable cause for a quantitative blood drug test. Oral fluid drug screening devices are not as accurate as laboratory tests. They need to be reasonably accurate, reliable and sensitive as screening devices as their use could result in arrests and convictions for drug-impaired driving. There is insufficient research to know the accuracy, reliability, and sensitivity of current versions of these devices marketed to law enforcement. Given the lack of basic research on devices, we are not yet in a position to develop model specifications or create a conforming products list, nor is it obvious that NHTSA needs to do so in order for law enforcement to use these devices. Development of best practices for use of these screening devices requires there be evidence that some uses, policies, and/or procedures are better than others. This evidence is not yet available. NHTSA requests that this recommendation be classified as Open, Acceptable Response.
