1. Understanding DWI – Legal Implications in North Carolina
In North Carolina, Driving While Impaired (DWI) refers to operating a vehicle under the influence of alcohol, drugs, or other impairing substances.
The legal Blood Alcohol Concentration (BAC) limit is 0.08% for drivers over 21. For commercial drivers, the limit is 0.04%, and for drivers under 21, any amount of alcohol can lead to a DWI charge.
That means if you have a BAC of 0.08 or higher, that is enough for the state of North Carolina to obtain a conviction. The same general logic applies to commercial drivers (Class A, Class B) and “provisional drivers” in North Carolina (under 21 years of age).
DWI is a serious offense, and North Carolina has strict laws and penalties in place to punish people convicted of driving under the influence – John Fanney, Raleigh DWI Lawyer
2. North Carolina’s DWI Laws and Penalties
Understanding the penalties associated with DWI offenses is essential. In North Carolina, the penalties vary based on the severity of the offense and whether it is a first or subsequent offense:
First Offense:
- Mandatory license suspension for 30 days with a reading of 0.08% or higher, with the possibility of limited driving privileges (Pretrial Limited Driving Privilege) after 10 days.
- Fines and jail time vary based on the severity of the offense, which considers the existence of aggravating factors, grossly aggravating factors, and mitigating factors, as the case may be.
Subsequent Offenses:
- Increased penalties, including longer jail time, higher fines, and extended license suspension.
- Multiple offenses can lead to permanent license revocation.
It’s important to note that DWI convictions can have long-lasting consequences, including increased insurance premiums and a criminal record.
3. The Role of Probable Cause in DWI Stops
Probable cause is a legal standard that must be met before law enforcement can make an arrest, conduct a search, or obtain a search warrant. In the context of a DWI stop, probable cause might be established by observing signs of impairment such as erratic driving, the smell of alcohol, or visible open containers of alcohol in the vehicle.
Establishing probable cause is often a crucial step in the DWI enforcement process, as it justifies the arrest and the administration of sobriety tests.
As such, challenging probable cause to arrest can serve as a powerful defense to DWI charges in Raleigh NC.
4. Introduction to Sobriety Testing
Sobriety tests are tools used by law enforcement to assess a driver’s level of impairment.
Field Sobriety Tests can broadly be classified into two categories: Standardized Field Sobriety Tests “SFSTs” and Chemical Tests.
Standardized Field Sobriety Tests:
Field Sobriety Tests may be conducted on scebe, typically during a traffic stop, and are designed to evaluate a driver’s balance, coordination, and ability to perform tasks that require divided attention.
SFST’s may also be conducted at the jail and law enforcement center at the discretion of the charging officer – John Fanney, Raleigh DUI Lawyer
Chemical Tests:
Chemical Tests involve analyzing a driver’s breath, blood, or urine to determine the presence and concentration of alcohol or drugs.
In North Carolina, refusal to submit to a chemical test can lead to immediate license revocation for at one year, per the NC implied consent law. This law sets forth that by driving on North Carolina roads, you have implicitly consented, you have given the state implied consent, to submit chemical testing if suspected of DWI.
5. Standardized Field Sobriety Tests (SFSTs) – An Overview
The Standardized Field Sobriety Tests, developed by the National Highway Traffic Safety Administration (NHTSA), are a battery of three tests used by officers to evaluate suspected impaired drivers. These tests include:
Horizontal Gaze Nystagmus (HGN) Test:
This involves following an object with the eyes to check for involuntary jerking, which can be exaggerated both by alcohol consumption and other factors.
Walk-and-Turn (WAT) Test:
This assesses a driver’s ability to follow instructions and maintain balance while walking in a straight line, turning, and returning.
One-Leg Stand (OLS) Test:
Here, the driver is asked to stand on one leg for a set period. Indicators of impairment include swaying, hopping, or using arms for balance.
These tests are designed to provide observable evidence of impairment, which, in combination with other factors, may establish probable cause for a DWI arrest.
6. Evaluating the Reliability of Standardized Field Sobriety Tests
The reliability of SFSTs has been a subject of much debate.
According to studies conducted by the NHTSA, when administered correctly, these tests may be accurate in identifying impairment.
However, several factors can impact their reliability:
Environmental Conditions:
Poor lighting, uneven road surfaces, and weather conditions can affect a person’s performance on these tests.
Physical or Medical Conditions:
Disabilities or injuries can impact balance and coordination, leading to false positives.
Officer Training and Bias:
The accuracy of SFSTs is heavily reliant on the administering officer’s training and objectivity.
Despite these potential issues, SFSTs remain a widely accepted tool for establishing probable cause in DWI cases in Wake County NC.
7. Probable Cause in the Context of DWI Stops in North Carolina
Probable cause is a critical legal concept in DWI cases. It refers to the reasonable belief that a person has committed a crime.
In the context of DWI stops in North Carolina, probable cause might include:
Observable Signs of Impairment:
Such as slurred speech, the smell of alcohol, red glass eyes, or erratic driving behavior.
Performance on Field Sobriety Tests:
Poor performance on SFSTs can contribute significantly to establishing probable cause to arrest.
Admissions of the Driver:
Statements made by the driver about their alcohol or drug consumption can also be used to establish probable cause.
