Driving Under the Influence of Narcotics

The same law that makes driving under the influence of alcohol illegal also makes driving under the influence of narcotics illegal. The key differences between an alcohol DUI and a narcotics DUI are the proof required to show the driver was under the influence, the legal and factual defenses and ,to some degree, the penalties.

Tenn. Code Ann. § 55-10-401 provides that:

• It is unlawful for any person to drive or to be in physical control of any automobile or other motor driven vehicle on any of the public roads and highways of the state of Tennessee, or on any streets of alleys, or while on the premises of any shopping center, trailer park or any apartment house complex, or any other premises which is generally frequented by the public at large, while under the influence of any intoxicant, marijuana, narcotic drug, or drug producing stimulating effects in the central nervous system.

These drugs can include marijuana, narcotics, and even prescription drugs. The latter, prescription drugs, often surprises people. Drivers who need to take medication should be aware that their prescription drugs may affect their ability to be in physical control of their vehicle. Many drugs, for example, make the person who takes them sleepy. Drivers should make sure they read the side effects for any prescribed or even over-the-counter medications they take.

Types of drug tests

Drivers in Tennessee give their implied consent to breath, urine, and blood tests. One key difference between an alcohol DUI and a drug DUI is that breath tests aren’t used in drug cases because there just aren’t breath machines that can register the concentration of drugs in a person’s system. Blood tests or urine tests normally require that the driver be taken to a local hospital where experienced medical professionals can draw the driver’s blood, or the driver can provide a urine sample. Drivers may also be asked to provide a urine or blood sample at a local police station.

Defense lawyers may try to suppress a blood test if there was too much time between the initial stop and when the blood was drawn or the urine sample was given.

A police officer will normally ask a driver to submit to field sobriety tests before requesting a urine or blood test. If a police officer suspects you were driving while under the influence of any drug, they will likely search your vehicle for evidence of any drugs. This often leads to a second challenge by defense lawyers – that the search was not constitutional. Police may need to obtain a warrant before they can conduct a car search.

Penalties for narcotic-based DUIs

Convictions for any DUI can result in jail time, fines, and suspension of the driver’s license. Drivers who have an alcohol DUI may be able to drive if they install an ignition interlock device (IID). IIDs do not apply to DUIs based on drug use since, again, there’s no drug test for breathing into a machine.

As part of any sentence, a judge may order a driver to complete a drug treatment program.
