Case law supporting the usage of this app:

Wisconsin v Alejandro Herrera Ayala:
The Wisconsin Court of Appeals addressed the admissibility of SFSTs administered in Spanish. The court found that the SFSTs were administered properly according to NHTSA guidelines. It was established that Ayala understood the instructions given in Spanish, and there was no evidence suggesting that the language of administration had compromised the reliability of the tests. Therefore, the court upheld the admissibility of the SFST results, highlighting that proper procedural compliance and the suspect’s comprehension were the key factors, not the specific language used.


United States v. Horn:
This case highlights the importance of administering SFSTs in strict accordance with NHTSA standards, focusing on the scientific reliability and proper execution of the tests rather than the language used. It serves as an example where adherence to standardized procedures can validate test results in any language, including Spanish​.


Rodriguez v. Texas (2013):
This case involved the admissibility of SFSTs, emphasizing that the proper administration of the tests according to established protocols is crucial. The language of administration, including Spanish, does not impact the admissibility as long as the tests are conducted correctly​.
