Tennessee has strict laws against impaired driving, with severe penalties for those convicted. Driving under the influence (DUI), also known as driving while intoxicated (DWI), includes impairment by drugs, controlled substances, cannabis, or tetrahydrocannabinol (THC), as well as alcohol. Tennessee law sets a blood alcohol concentration (BAC) limit of 0.08% for adults over 21, with zero tolerance for underage drivers. Impaired driving is determined not only by BAC but also by an individual's ability to safely operate a motor vehicle, including their clearness of mind and self-control. Underage drivers with a BAC of 0.02% or more are considered impaired, facing license suspension, fines, and public service work. Tennessee law enforcement employs various tactics, including field sobriety tests and breathalyzers, to combat impaired driving, with severe consequences for non-compliance.

Underage driving while impaired
In Tennessee, driving under the influence of alcohol or drugs is a crime. This includes driving while impaired by any intoxicant, marijuana, controlled substance, or drug that affects the central nervous system. Underage driving while impaired is a specific offence for individuals under the age of 21.
The offence of underage driving while impaired is established for individuals aged 16 or over but under 21. It is considered a lesser offence than driving while intoxicated. For those under 18, it is classified as a delinquent act. The penalties for underage driving while impaired vary depending on the age of the offender.
For individuals aged 16 or older but under 18, underage driving while impaired is punishable by a driver's license suspension of one year, a fine of $250, and possible court-imposed public service work. This age group is considered to have committed a delinquent act.

It is important to note that the presence of narcotic or barbital drugs in an individual's system, even if lawfully obtained, does not serve as a defence for violating the underage driving while impaired offence. The blood alcohol concentration limit for determining impairment is 0.02%.

Driving under the influence of drugs
Tennessee law prohibits anyone from driving or being in physical control of any motor vehicle while under the influence of drugs. This includes any intoxicant, marijuana, controlled substance, or drug that affects the central nervous system. The law also covers the combined influence of alcohol and drugs, which can impair a person's driving ability.
Tennessee's DUI (driving under the influence) law states that it is illegal for adults aged 21 and older to have a blood alcohol concentration (BAC) of 0.08% or more while driving. For those operating a commercial vehicle, the limit is 0.04%. The state has a zero-tolerance policy for underage drinking and driving, with a limit of 0.02% BAC for drivers under 21.
The consequences of a DUI conviction in Tennessee can be severe. For a first offense, a driver will typically lose their license for one year and pay a fine ranging from $350 to $1,500. They may also be required to install an ignition interlock device (IID) in their vehicle, which prevents the car from starting if alcohol is detected on the driver's breath. A DUI conviction can also result in increased insurance rates, towing fees, attorney fees, and other costs.
In addition to legal consequences, a DUI conviction can have lasting impacts on a person's life. It can affect their employment prospects, housing options, and ability to obtain specialty licenses or security clearances. It is important for drivers in Tennessee to be aware of the risks and consequences of driving under the influence of drugs or alcohol and to make safe choices to protect themselves and others on the road.
Tennessee law enforcement uses various tactics to identify and prosecute impaired drivers. This includes field sobriety tests, such as breathalyzer tests, coordination tests, and blood or urine samples. Refusing to participate in these tests can result in additional consequences, including license revocation. Law enforcement does not need to prove actual impairment, as a breath or blood test showing a BAC above the legal limit is sufficient evidence for a DUI charge.

Zero-tolerance for underage intoxicated driving
Tennessee has a zero-tolerance policy for underage intoxicated driving. This means that individuals under the age of 21 are prohibited from driving or being in physical control of a motor vehicle while under the influence of any drug, intoxicant, or substance that impairs their ability to drive safely. This includes marijuana, controlled substances, central nervous system stimulants, and alcohol.
The legal limit for blood alcohol concentration (BAC) in Tennessee is 0.08% for adults over the age of 21. However, for individuals under 21, the BAC limit is much lower at 0.02%. This means that even a small amount of alcohol can result in a DUI (driving under the influence) or DWI (driving while intoxicated) charge.
The consequences of underage intoxicated driving in Tennessee can be severe. For individuals aged 16 to 20, driving with any detectable amount of alcohol in their system is illegal. If convicted, the offender's driver's license will be suspended for one year, and they will be subject to a fine of $250. The court may also impose additional punishments, such as public service work.
Law enforcement officers in Tennessee have multiple tactics to determine if a driver is intoxicated, including field sobriety tests such as breathalyzer tests, coordination tests, and balance tests. Refusing to participate in these tests can result in a DUI charge and, in extreme cases, a court-ordered blood or urine sample may be required.
The state of Tennessee takes impaired driving seriously, and the consequences of a DUI conviction can be life-changing. It is important for all drivers, regardless of age, to understand the risks and consequences of driving under the influence of any substance that impairs their ability to operate a motor vehicle safely.

Refusing breathalyzer or sobriety tests
In Tennessee, a person is considered to be driving under the influence (DUI) if their blood alcohol content (BAC) is 0.08% or higher. For those under 21 years of age, the limit is lower at 0.02% BAC. Driving under the influence of drugs, including those prescribed by physicians, is also considered a DUI.
In Tennessee, you have the right to refuse a field sobriety test if asked to take one by a law enforcement officer. These tests are voluntary and your participation is not required by law. However, refusing to take a field sobriety test may result in consequences. For example, the officer may still arrest you for DUI based on other evidence, such as your behaviour or appearance. Tennessee law allows officers to have probable cause based on the "totality of the circumstances", even if you pass the field sobriety test.
Implied consent laws in Tennessee state that by driving on Tennessee roads, you have implicitly agreed to submit to a breathalyzer test or other chemical tests if asked by a police officer. Refusing to take a breathalyzer test can result in serious consequences, including license revocation, fines, and even jail time. These penalties are administrative and enforced by the Tennessee Department of Safety and Homeland Security, rather than criminal courts. Prosecutors often interpret refusal as a sign of guilt and use it as evidence against you in court. They may argue that you declined the test because you knew you were intoxicated.
It is important to note that refusing a breathalyzer test does not eliminate other evidence. Officers can rely on their observations, dashcam footage, and the results of field sobriety tests to build a case. In some situations, officers may obtain a warrant to conduct a blood test, negating the refusal altogether.
If you are facing DUI charges or have refused a breathalyzer test, it is recommended to consult with an experienced DUI defense attorney who can advise you of your legal options and protect your rights.
