Implied consent laws refer to the rules and regulations that drivers implicitly agree to follow when they obtain a driver's license. These laws are based on the principle that driving is a privilege and not a right, and they aim to promote road safety and deter drunk or impaired driving. One of the key aspects of implied consent laws is the requirement to submit to chemical testing, such as breath, blood, or urine tests, to determine blood alcohol content (BAC) or the presence of drugs when pulled over by law enforcement. Refusing to comply with these tests can result in penalties, including license suspension, fines, and even criminal charges in some states. These laws vary by state, and it is important for drivers to understand their rights and responsibilities under the implied consent laws in their specific jurisdiction.

What You'll Learn

Implied consent laws apply to all 50 states
The rationale behind implied consent laws is that driving is a privilege, not a right, and with this privilege come certain responsibilities, such as adhering to laws that promote safety on the roads and deter drunk or impaired driving. When you apply for a driver's license, you sign forms agreeing to comply with requests from law enforcement officers for chemical testing if they have probable cause to suspect impairment.
While all 50 states have implied consent laws, the specific penalties for refusing to take a BAC test vary across states. In some states, such as Minnesota, refusing to submit to a breath test is a separate crime, and your license will be automatically suspended. In other states, like Wyoming, there are no administrative or criminal penalties for refusing a breath test, but your refusal can be used as evidence of culpability in a DUI case.
It is important to note that implied consent laws do not mean that you are required to submit to any and all requests from law enforcement officers. The officer must have probable cause to believe that you are under the influence, and your refusal may still result in certain consequences, such as license suspension or even criminal charges in some states. Additionally, defense attorneys often challenge implied consent laws on the basis that driving is a necessity for leading a productive life and that refusing a test should not result in both criminal action and license suspension.
While the specifics of implied consent laws may differ across states, the underlying principle remains: by choosing to drive on public roads and obtaining a driver's license, you implicitly agree to submit to chemical testing as a condition of that privilege. These laws are in place to balance the need for road safety with the rights of individuals, and it is important for drivers to understand their responsibilities and the potential consequences of non-compliance.

Consenting to sobriety tests when pulled over
When you apply for a driver's license, you consent to field sobriety tests and chemical tests to determine impairment when driving a motor vehicle. This is known as implied consent law. In other words, when you get your license, the government is essentially saying, "We're going to let you drive on public roads, but that means you agree to obey the law." This includes consenting to breath, blood, or urine tests to determine your Blood Alcohol Content (BAC) or whether drugs, including alcohol, are in your system.
If you refuse to take a chemical test, you are likely to be arrested for 'per se intoxication'. This means that if you refuse to cooperate with field sobriety tests, you can still be arrested if the officer has probable cause to believe you are intoxicated and a danger to the public or yourself. For example, you may have been weaving, made an illegal lane change, or drove without headlights. While the police cannot pull you over for no reason at all, it is not difficult for them to find a reason.
The penalties for refusing to take these tests are often more severe than if the driver fails one of the requested standardized field sobriety tests. In most states, your license is automatically suspended for up to a year or more. You may also face fines and fees, and some states impose harsher penalties for refusing a DUI test than failing one. For example, in California, a first-time refusal triggers a one-year license suspension, while in Ohio, there is a mandatory minimum six-day jail sentence for a second DUI charge within six years.
It is important to note that police officers cannot force you to take a breath test, blood test, or urine test. However, refusing to take these tests is illegal and will result in penalties. Therefore, it is generally recommended to comply with the requests of law enforcement officers to take these tests.

Refusal to submit to tests results in penalties
When a person obtains a driver's license, they implicitly agree to adhere to implied consent laws, which include submitting to alcohol or drug testing when law enforcement suspects impairment. This is a condition of driving on public roads. Refusing to take a breath, blood, or urine test after being arrested for DUI (driving under the influence) triggers harsher DUI penalties and a mandatory driver's license suspension, regardless of the outcome of the DUI case. The penalties for refusing to take these tests are often more severe than if the driver fails one of the requested standardized field sobriety tests.
In California, for example, a first-time refusal triggers a one-year license suspension, while a second refusal within 84 months results in a two-year suspension. If convicted of a chemical refusal, you face enhanced penalties in addition to your underlying sentence for a DUI. For instance, a first DUI offense in 10 years with a refusal would result in an additional 48 hours in county jail and a minimum nine-month DUI school.
In Arizona, refusal may cause drivers to automatically lose their driving privileges for 12 months, and they may be required to complete a drug and alcohol education program before reinstatement. While drivers can lawfully refuse to participate in field sobriety tests and PAS tests, they may still be prosecuted for a DUI offense and face license suspension if they refuse chemical testing after a lawful DUI arrest.
The reasoning behind implied consent laws is that driving is a privilege, not a right, and law enforcement must determine if a driver is a danger to the public. By signing the forms to apply for a driver's license, individuals agree to comply with requests by law enforcement officers to take chemical tests to determine their blood-alcohol content (BAC). These tests include breath, blood, and urine testing.

Challenging implied consent laws
Implied consent laws refer to the rules that an individual agrees to follow when they obtain a driver's license. These laws are in place to promote safety on the roads and deter drunk or impaired driving. When obtaining a driver's license, individuals implicitly agree to submit to chemical testing, including breath, blood, and urine tests, to determine their blood alcohol content (BAC) or the presence of drugs in their system. This is based on the understanding that driving is a privilege and not a right, and individuals must comply with law enforcement requests to ensure public safety.
However, implied consent laws have been challenged by criminal defense attorneys on several grounds. One common argument is that these laws can subject individuals to double jeopardy, facing both criminal charges for DUI and license suspension. To address this, some states have placed license suspension under administrative action by the DMV rather than treating it as a criminal issue. Defense attorneys also argue that implied consent laws can disproportionately impact individuals who rely on driving to maintain a productive and normal life.
Another challenge to implied consent laws is based on the right against self-incrimination. Some argue that being forced to submit to chemical testing violates this right. However, court decisions have held that this privilege pertains specifically to self-incriminating statements and does not extend to the provision of physical evidence, such as chemical test results.
It is worth noting that implied consent laws are in place to address the significant impact of alcohol-related crashes and to enhance the enforcement of DUI laws. While challenges to these laws may arise, the primary goal is to promote road safety and protect the public from impaired driving.

Implied consent vs. explicit consent
Implied consent and explicit consent are two different types of consent that apply in various contexts, including marketing and driving.
Implied Consent
Implied consent is inferred from an individual's actions or inaction. For example, in the context of marketing, implied consent is when someone gives you their contact information but does not explicitly state that they want to receive marketing messages from your brand. In the context of driving, implied consent refers to the understanding that by obtaining a driver's license, individuals agree to comply with certain laws and requests from law enforcement, such as providing their license and registration when pulled over or submitting to alcohol or drug testing when suspected of impaired driving.
Explicit Consent
Explicit consent, on the other hand, is when individuals provide clear and unambiguous permission, often through a written statement or an affirmative action. In marketing, explicit consent is obtained when an individual is asked for permission to send them marketing emails, and they actively agree by manually opting in through a checkbox or written consent. In the context of driving, explicit consent is not typically required for every interaction with law enforcement. However, individuals always have the right to refuse any requests or commands that are not based on reasonable suspicion or probable cause.
Differences and Considerations
The main difference between implied and explicit consent is the level of explicitness in the agreement. With implied consent, the agreement is inferred from the individual's actions or inaction, whereas explicit consent requires a direct and active agreement. It is important to note that the legality and applicability of each type of consent can vary depending on the context and the applicable data protection laws or privacy regulations. For example, in some jurisdictions, explicit consent may be required for certain types of data collection or marketing communications. Additionally, implied consent may be restricted to specific circumstances or time frames.
In the context of driving, implied consent laws have been challenged by criminal defense attorneys, arguing that driving is a necessity for leading a normal life and that individuals should not be subject to both criminal action and license suspension for the same offence. However, state officials maintain that driving is a privilege and that law enforcement must have the tools necessary to address impaired driving and ensure the safety of the public.

Frequently asked questions
Implied consent laws are rules that you agree to follow when you get your driver's license. This means that if you are pulled over for suspicion of driving under the influence (DUI), you are required to submit to chemical tests to determine your blood alcohol content (BAC).
Refusing to take a chemical test will likely result in immediate penalties, including license suspension, fines, and additional penalties. In some states, refusing a chemical test can lead to criminal charges.
Chemical tests include breath, blood, and urine testing. A breath test can be administered at any location, whereas blood and urine tests can only be performed at a medical or detention facility.
Implied consent laws also apply to field sobriety tests, such as the one-leg stand, walk-and-turn, and horizontal gaze nystagmus test. If you refuse to take these tests, you may face administrative penalties and license suspension.
