Addressing the behavioral health, substance use, and legal implications involved, this comprehensive guide provides readers with essential insights into field sobriety testing in Arizona.
According to the Arizona Governor’s Office of Highway Safety (GOHS), understanding these rights is crucial, as the state conducted over 28,500 field sobriety tests in 2022 alone.
But are field sobriety tests mandatory in Arizona? Let’s get answers now and then dive into more details.
Arizona law dictates the responsibilities and rights of drivers regarding the refusal of such tests, emphasizing that while certain tests can be refused without penalties, this may lead to potential legal consequences depending on the circumstances surrounding the DUI stop.
Additionally, appropriate testing conditions are essential for ensuring the accuracy of field sobriety tests and maintaining the validity of evidence in legal proceedings.
Current DUI Enforcement in Arizona
The Arizona Department of Public Safety (DPS) reports significant DUI enforcement activity in 2022:
Total DUI Arrests:
- 22,384 total DUI arrests
- 4,127 aggravated DUI cases
- 3,562 drug-related DUI arrests
- 14,695 alcohol-only DUI arrests
Police officers play a crucial role in conducting field sobriety tests during DUI stops.
Average Blood Alcohol Concentration (BAC) readings showed concerning levels:
- Mean BAC: 0.152
- Median BAC: 0.147
- 45% of arrests involved BAC over 0.15
- 22% of arrests involved BAC over 0.20
Common field sobriety tests such as the one-leg stand, horizontal gaze test, and walk-and-turn test are frequently administered by police officers as a preliminary measure to assess a driver’s sobriety.
Field Sobriety Tests: Legal Framework
Arizona’s DUI laws create a specific framework for sobriety testing. While chemical tests fall under implied consent laws, standard field sobriety tests remain voluntary.
These tests follow standardized procedures established by the National Highway Traffic Safety Administration (NHTSA).
The Arizona Supreme Court has consistently upheld this distinction, most recently in State v. Martinez (2021).
The three standardized tests used in Arizona demonstrate varying reliability rates according to NHTSA research:
Horizontal Gaze Nystagmus:
- 77% accuracy rate
- Required officer certification
- 92% court admission rate
- Most scientifically validated
Walk-and-Turn:
- 68% accuracy rate
- Eight distinct scoring elements
- 85% court admission rate
- Most commonly administered
One-Leg Stand:
- 65% accuracy rate
- Four scoring elements
- 83% court admission rate
- Most affected by physical conditions
Refusal Statistics and Outcomes
The GOHS provides detailed data on test refusals and their consequences in 2022:
Field Sobriety Test Refusals:
- 11,970 drivers refused FSTs
- 42% overall refusal rate
- 85% of refusals led to arrests
- 73% conviction rate for refusals
Refusing field sobriety tests can lead to a driver’s license suspension.
Chemical Test Refusals:
- 3,580 chemical test refusals
- 16% refusal rate
- 100% license suspension rate
- 24-month average suspension duration
Consequences of Refusing a Field Sobriety Test
Refusing a field sobriety test in Arizona can have consequences. While it is not mandatory to take a field sobriety test or any form of EtG test or drug test, refusing to do so can lead to:
- Arrest: The police officer may arrest the driver for DUI based on other evidence, such as the driver’s behavior, speech, or the presence of alcohol or drugs in the vehicle.
- License suspension: Refusing a field sobriety test can result in a driver’s license suspension, which can last for a minimum of 12 months.
- Chemical test: The police officer may request a chemical test, such as a breathalyzer or urine test, to determine the driver’s blood alcohol concentration (BAC).
Impact on Court Proceedings
Arizona court records from 2022 reveal conviction rates based on available evidence:
Cases with Multiple Evidence Types:
- FSTs plus chemical tests: 92% conviction rate
- Chemical tests only: 76% conviction rate
- FSTs only: 65% conviction rate
- Officer observation only: 42% conviction rate
Evidence from field sobriety tests can significantly impact the status of a driver’s license in court proceedings regarding sobriety, potentially leading to its revocation if the tests are refused.
The Maricopa County Attorney’s Office reports that cases involving FST evidence typically resolve 35% faster than those without such evidence.
Medical and Environmental Factors
Research from the Arizona Department of Health Services identifies several factors affecting FST performance:
Medical Conditions Impacting Tests:
- 15% of drivers report balance disorders
- 22% cite arthritis or joint problems
- 18% have vision impairments
- 12% report neurological conditions
Environmental Factors Noted in Police Reports:
- Weather conditions affected 28% of tests
- Poor lighting impacted 23% of tests
- Uneven surfaces influenced 31% of tests
- Traffic noise affected 19% of tests
Legal Rights and Requirements

- Cannot physically compel FST participation
- Must read implied consent warnings
- Must document refusals properly
Driver Rights:
- May decline FSTs without direct penalty
- Can request an attorney consultation

Recent Legal Developments
The Arizona Supreme Court and Legislature have enacted several changes in 2022-2023:
New Requirements:
- Mandatory body camera usage during FSTs
