National Highway Traffic Safety Administration (NHTSA)
The agency within the United States Department of Transportation that administers traffic safety programs. NHTSA's duties include funding studies on field sobriety tests and training law enforcement officers in the administration of the standardized field sobriety test battery. This is the agency responsible for putting out the NHTSA training manual that most police officers are trained on. The manual teaches law enforcement officers how they are to perform the field sobriety tests that drivers are tested on. It explains the method and procedure that is to be followed. Civilians such as myself can also take the same class that the police take and therefore also can become certified to administer the NHTSA tests. This is helpful for Maryland drivers because it serves as a way to check the procedure and validity that was used in a given case. If the tests are not properly administered the validity of the test is called into question. The NHTSA manuals from prior years are available on this website for your review.
