What typically happens during a DUID stop?
Answer:
An officer may ask for driving documents, investigate suspected impairment, and request field sobriety testing. If an arrest follows, chemical testing may be requested under applicable rules. The reason for the stop, the officer’s observations, testing procedures, and any refusal all need review; an arrest is not a conviction.
Legal clarification — October 16, 2026: Testing rules have exceptions and consequences. South Carolina Code § 56-5-2948 requires field sobriety testing in specified fatal motor-vehicle incidents when the driver is physically able. Chemical-test refusal is a separate issue under §§ 56-5-2950 and 56-5-2951 and can affect driving privileges and be used in court.
A drug-related DUI investigation often begins with a traffic stop. An officer may ask for a driver’s license, registration, and proof of insurance, then ask questions about the driver’s activities or possible substance use. Whether the stop and any further investigation were lawful depends on the facts.
Remain calm and respectful, provide required documents, and avoid false answers. You may choose to remain silent about suspected wrongdoing and ask to speak with an attorney.
If impairment is suspected, the officer may request field sobriety testing. Our attorney describes the eye test, walk-and-turn test, and one-leg stand. Testing conditions, stress, physical limitations, and medical issues may be relevant when evaluating performance. An officer’s conclusions and the other evidence should be examined carefully.
An arrest may be followed by a request for chemical testing. Field sobriety testing and chemical testing are separate procedures with different legal rules. Refusal should not be described as a consequence-free choice or assumed to improve the outcome.
South Carolina law also includes a field-testing requirement in certain fatal motor-vehicle incidents when the driver is physically able. The particular circumstances matter.
A DUI defense attorney can review the reason for the stop, recordings, observations, testing, and any licensing action. An arrest does not establish guilt, and no specific result can be promised.
