DWI's are very complicated, but we try our best to explain every detail so that it can make more sense.  When collecting evidence to build a case against you, officers adhere to strict guidelines.  Whether you are guilty or not, it feels scary and frustrating to be pulled over while driving. Sometimes, you are not sure what violation you may have committed. But once you find out and the stop is over, your next steps are crucial.

If pulled over, the officer should be pulling you over for some violation of a traffic Law.  That could include a faulty light, speeding, or even a suspicion of Driving While Intoxicated.  Whether it’s a checkpoint or you’ve been pulled over, the officer will approach your vehicle and ask for your license and registration.   If he or she believes you may have been drinking alcohol, they will likely ask you certain questions to elicit evidence of potential intoxication:

North Carolina DWI's: The Arrest From Start to Finish

“Have you been drinking tonight?”

“How much have you had to drink?”

“Where are you coming from?”  (to see if you mention a bar or restaurant).

He or she will likely investigate further to determine your level of impairment. This may start with what is called DWI Pre-exit Tests.


These consist of tests that can be performed while still seated in your vehicle. They can include counting, reciting the alphabet, or finger dexterity tests (touch thumb to fingertip on each hand while counting).

If the officer feels you may be intoxicated, he or she will ask you to exit the vehicle. Once out of the vehicle, the officer will ask you to perform a battery of tests. The three common roadside sobriety tests are the One-Leg Stand, the Walk-and-Turn, and the Horizontal Gaze Nystagmus.

The officer requests you stand with one leg out in front of you, with the raised foot pointed up and both legs straight, hands at your side. You will be asked to count out loud until told to stop. The “clues” the officer is looking for in this test are raising your arms for balance, hopping, putting your foot down, or swaying.

The next test is the Walk-and-Turn. In this test, the officer will ask you to walk a straight line, making contact heel-to-toe, for nine steps, while watching your feet, counting out loud, and keeping your hands at your side.  You'll be required to turn around in a specific way and repeat the 9 steps back in the same way. Some of the “clues” that officers look for are starting the test too soon, using hands for balance, stepping off line, missing heel-to-toe by more then a half-inch, an incorrect turn, a wrong number of steps, stopping the test early or not maintaining balance during instructions.

Nystagmus is the involuntary twitching of the eyes. Nystagmus can be caused for several reasons, one is alcohol impairment. The test is performed by the officer asking you to follow a stimulus while holding your head still. An officer will ask you to follow the stimulus from left to right, watching each eye for certain “clues.” while performing the test, the officer is looking to see if your eyes do not track smoothly, or to see if you have ‘distinct’ Nystagmus when your eyes are all the way to one side. It is a common misbelief that this test is looking for whether you can follow the stimulus without moving your head, and while the officer will make note of it, it is not the primary purpose of the test. Therefore, no one but the officer knows whether you ‘passed’ the test or not.  This particular test requires the officer to be certified as an expert in court in order to testify as to the results.  Therefore a detailed analysis of the officer's instructions and understanding of this test is required.

In addition to these tests, the officer will likely ask you to blow into a Handheld Breathalyzer Test; known as the AlcoSensor.  The AlcoSensor is used by the officer to determine your level of intoxication. The numerical results of this test CANNOT be used at trial. The officer can only testify as to whether the machine indicated a positive reading for alcohol on your breath.  Once the AlcoSensor is administered and the Roadside Sobriety Tests are completed, the officer will make a determination as to whether they believe they have probable cause to arrest you.

In most instances, you will be taken to a local police precinct for the administration of this test. The test is similar to the AlcoSensor test in that there is a machine being used to measure the level of alcohol on your breath.  Before administering this test, the officer must read you your rights regarding the test and your right to refuse.

 This test is called an “implied consent” test which means that, by driving on North Carolina roads, you have ‘implied’ to ‘consent’ to the test. This test will produce a numerical value for your breath/alcohol level that WILL be used against you in court.  Unfortunately, since this test is an ‘implied consent’ test, the refusal to provide a breath sample will result in the loss of your license for 12 months.  Keep in mind, however, if you are found guilty of DWI you will also lose your license.  Also, even if you refuse to provide a breath sample, the arresting officer can still attempt to obtain a warrant to take a sample of your blood, even without your consent.

 After the administration of the Intoxilylzer 5000 or Intoximeter EC/IR II Breathalyzer Test, you will be booked and go before a Magistrate. The Magistrate will make a determination as to whether to set bond or not and will advise you of your charges and your rights.
