McCutchen Vaught Geddie & Hucks, P.A. knows that Memorial Day weekend in Myrtle Beach brings heavy traffic, crowded entertainment areas, late nights, and increased law enforcement visibility. Drivers may encounter DUI checkpoints on or near busy roads leading to restaurants, hotels, beach access points, and nightlife areas. South Carolina law allows properly conducted sobriety checkpoints, but drivers still have rights during a stop. Knowing what to expect before the holiday weekend can help you make safer choices, avoid unnecessary mistakes, and respond calmly if you are questioned by law enforcement.
Why DUI Checkpoints Increase Around Memorial Day Weekend 
Memorial Day weekend often marks the start of the summer travel season in Myrtle Beach, South Carolina. Local residents, vacationing families, college students, motorcycle riders, and out-of-state visitors all share the same major roads, including U.S. Highway 17, Kings Highway, Ocean Boulevard, Robert Grissom Parkway, and routes near the Grand Strand. When more people are on the road after dinners, concerts, beach outings, and private gatherings, law enforcement agencies often increase DUI patrols and sobriety checkpoints as part of broader public safety efforts.
A DUI checkpoint is not the same as a routine traffic stop. At a checkpoint, officers stop vehicles according to a neutral plan rather than waiting to observe a specific traffic violation. The purpose is usually to screen drivers for signs of impairment, confirm licensing and registration, and remove unsafe drivers from the road when officers believe there is legal cause to investigate further. For a driver who has never been through one, the experience can feel stressful, especially when flashing lights, cones, and multiple officers are present.
The best way to approach Memorial Day driving is to plan before the evening begins. Decide who will drive, whether a rideshare service is available, where you will park, and what you will do if plans change. A person can feel fine at dinner and still be over the legal limit later. Alcohol affects people differently based on body weight, food intake, medication, fatigue, and how quickly drinks are consumed. A safe plan protects you, your passengers, pedestrians, and other drivers.
Are DUI Checkpoints Legal in South Carolina?
DUI checkpoints can be legal in South Carolina when law enforcement follows constitutional and procedural safeguards. A checkpoint cannot be random in the sense that officers decide on the spot whom to stop based on appearance, vehicle type, or personal preference. The operation should be planned in advance, supervised, visible to approaching drivers, and conducted in a way that limits unnecessary intrusion.
A proper checkpoint often includes marked police vehicles, cones or signs, uniformed officers, and a neutral stopping pattern. For example, officers may stop every vehicle or every third vehicle depending on traffic flow and the written plan. The stop should be brief unless an officer observes signs that create reasonable suspicion or probable cause for further investigation. Those signs may include the smell of alcohol, slurred speech, open containers, inconsistent answers, bloodshot eyes, confusion, or unsafe driving behavior near the checkpoint.
If you are charged after a checkpoint stop, the legality of the checkpoint may matter. A Myrtle Beach criminal defense attorney may examine whether the location was approved, whether proper supervision existed, whether officers followed the stopping pattern, whether the checkpoint caused unreasonable delay, and whether the officer had a lawful basis to extend the encounter.

What Drivers Should Do When Approaching a Checkpoint
When you see a checkpoint ahead, slow down safely, follow traffic directions, and remain calm. Sudden turns, abrupt lane changes, or unsafe maneuvers may draw attention and could give officers a separate reason to stop you. You do not need to be overly talkative or argumentative. A calm, respectful approach usually helps keep the encounter brief.
Have your license, registration, and proof of insurance ready if requested. Roll down your window enough to communicate clearly. Keep your hands visible. If an officer asks where you are coming from or whether you have been drinking, you should understand that your answers may later appear in a police report. You may provide required identification and vehicle documents, but you do not have to volunteer extra details about your night.
Drivers sometimes make the mistake of trying to talk their way out of suspicion. Long explanations, jokes, nervous comments, or guesses about how much alcohol they consumed can create problems. A simple, polite response is usually better than an emotional one. If an officer asks you to step out of the car, comply safely. Do not resist, argue on the roadside, or physically interfere with the investigation. Legal challenges are usually made later through the court process, not during the checkpoint encounter.

Client Reviews
Field Sobriety Tests and Breath Testing
At a DUI checkpoint, an officer may ask a driver to perform field sobriety tests. These can include walking heel to toe, standing on one leg, or following a stimulus with the eyes. Many drivers do not realize that these tests can be affected by fatigue, medical conditions, footwear, uneven pavement, anxiety, poor lighting, age, or prior injuries. Myrtle Beach visitors may also be driving after long travel days, sun exposure, dehydration, or extended time outdoors, all of which can affect balance and appearance.
South Carolina also has implied consent rules related to chemical testing after a DUI arrest. Refusing a breath, blood, or urine test can carry license consequences, even before the criminal case is resolved. A refusal may also be used as evidence in court. At the same time, breath testing is not immune from challenge. Machines must be maintained, officers must follow testing procedures, and the circumstances of the stop and arrest still matter.
Because DUI cases often involve both criminal penalties and license issues, it is wise to speak with counsel quickly after an arrest. The firm’s guidance on South Carolina DUI laws at https://lawyersatthebeach.com/blog/understanding-south-carolina-dui-laws-what-you-need-to-know-if-charged/ explains how DUI charges can affect driving privileges, court obligations, and future consequences.
Common Memorial Day DUI Scenarios in Myrtle Beach
A common situation begins with a group visiting Myrtle Beach for the holiday weekend. They spend the afternoon near the beach, eat dinner, and stop at a bar before returning to a hotel or rental property. The driver believes enough time has passed, but police stop the vehicle at a checkpoint near a busy corridor. The officer smells alcohol and asks the driver to step out. Even if the driver was not speeding or swerving, the checkpoint contact can lead to a DUI investigation if the officer observes signs of impairment.
Another scenario involves a local resident who only had a couple of drinks at a cookout. The drive home is short, and the driver assumes there is little risk. A checkpoint changes that assumption. The officer asks questions, notices an open container left by a passenger, and begins a broader investigation. Even when facts seem explainable, the driver may still be arrested and forced to defend the case in court.
A third situation involves a driver who is completely sober but nervous. The driver stumbles over answers, struggles to find registration, or appears confused because of stress. This can happen to anyone. If the encounter escalates, the details matter. Video footage, officer notes, body camera recordings, checkpoint plans, and test results may all need careful review.
What Penalties Can Follow a DUI Charge?
A DUI charge in South Carolina can affect far more than one holiday weekend. Potential consequences may include license suspension, fines, assessments, alcohol education requirements, ignition interlock requirements in some circumstances, increased insurance costs, court appearances, probation, and possible jail time depending on the facts. Prior DUI convictions, a high blood alcohol concentration, an accident, injuries, or a child passenger can raise the stakes.
The personal consequences can also be serious. A DUI arrest may affect employment, professional licensing, school plans, military service, family responsibilities, and travel. For visitors, a Myrtle Beach DUI can create the added burden of returning to South Carolina for court or coordinating representation from another state. These practical concerns are one reason early legal guidance can be valuable.
First-time offenders should not assume that a first offense is minor or automatic. There may be defenses, evidentiary issues, negotiation options, or administrative deadlines that deserve attention.

How a Defense Attorney Reviews a Checkpoint DUI Case
A defense attorney does not look only at the breath test number or the officer’s conclusion. The review often begins with the checkpoint itself. Was there a written plan? Did supervisors approve the operation? Were officers following neutral procedures? Was the checkpoint visible and safe? Did the stop last longer than necessary without a lawful reason? These questions can affect whether evidence should be challenged.
The attorney may also review the officer’s observations. Body camera footage may show whether speech was actually slurred, whether the driver followed instructions, whether the roadway was level, and whether the officer explained tests correctly. Dash camera footage may show whether the driver operated the vehicle safely before reaching the checkpoint. Maintenance records and calibration information may matter if breath testing occurred.
A strong defense is built from details. Sometimes the issue is whether the checkpoint was properly conducted. Sometimes the issue is whether the officer had enough evidence to arrest. Sometimes the issue is whether testing procedures were reliable. Sometimes the best path involves negotiating a result that reduces long-term harm. No attorney can promise a certain outcome, but careful case review can help a driver understand available options.
Smart Planning Before Summer Nights in Myrtle Beach
The simplest way to avoid a DUI checkpoint problem is to avoid driving after drinking. That advice may sound obvious, but holiday weekends create situations where plans change. A designated driver may decide to drink. A rideshare may take longer than expected. A hotel may seem close enough to drive. A person may feel less impaired than the law would consider them. Those are the moments when planning matters.
Before you go out, choose a driver who will not drink at all, not someone who will drink less. Save rideshare apps and taxi numbers before the evening starts. Consider walking only when the route is safe, well-lit, and lawful for pedestrians. Keep in mind that Myrtle Beach traffic may be heavier around beach access areas, restaurant districts, and major event locations. Give yourself extra time so you do not feel pressured to make a risky decision.
Drivers should also make sure their vehicle is in order. Expired tags, broken lights, unsafe lane changes, and missing proof of insurance can lead to separate problems. During high-visibility enforcement periods, small issues may draw attention. Safe driving, proper documents, and a sober plan are the best protection.
When to Call a Lawyer After a DUI Arrest
If you are arrested at or near a Myrtle Beach DUI checkpoint, it is wise to speak with a lawyer as soon as possible. Court dates, license deadlines, evidence preservation, and witness memories can move quickly. Waiting too long may make it harder to obtain video footage, identify procedural issues, or protect driving privileges.
You should also avoid discussing the facts of the case on social media or with people who do not need to know. Statements about where you were, what you drank, or how you felt can create unnecessary complications. Keep paperwork from the jail, bond court, towing company, and law enforcement agency. Write down what you remember while details are fresh, including the checkpoint location, time, officer statements, testing instructions, and names of passengers or witnesses.
