What can I do if I disagree with the results of a breath analysis or blood test after a violent offence? (Spanish): ¿Qué puedo hacer si no estoy de acuerdo con los resultados de un análisis de aire espirado o de sangre después de un delito violento?
If the police have cause to think you are under the influence of alcohol or drugs when they arrest you for a violent offence, you must submit to a breath test and breath analysis (for alcohol), a saliva test and blood test (for drugs), or a breath test, saliva test and blood test (for combined use of alcohol and drugs). If you disagree with the results of the breath test or blood test, then you can have a counter-test done. This leaflet describes in Spanish the rules and procedures for alcohol and drug testing and counter-testing.
