Texas trains DWI officers with the NHTSA Standardized Field Sobriety Student Testing Manual. The NHTSA SFST Manual is the national standard for DWI enforcement. Every DWI defense lawyer should own a copy.
The manual includes, inter alia, training on how an officer should testify in court. DWI officers are professional witnesses, trained and paid to speak in court. Some of the manual’s tips are pretty mundane; read the police report beforehand, listen carefully, take your time, speak clearly. Not too exiting.
