TRAFFIC RULES IN SOUTH CAROLINA

Heading to Darlington Raceway for the Goodyear 400? Taking a moment to understand South Carolina’s road rules can help ensure a smooth and stress-free journey. While many regulations are standard across the U.S., there are a few local specifics worth knowing before you set off.

Driving basics in South Carolina

• Drive on the right-hand side of the road at all times
• Follow all traffic signs and signals
• Right turns on red are allowed after a full stop, unless stated otherwise
• At four-way stops, the first vehicle to arrive has priority; if vehicles arrive together, the one on the right goes first
• Be aware of slow-moving farm vehicles on rural roads

Speed limits

• Residential areas: 25–30 mph (40–48 km/h)
• Rural roads and highways: 55–65 mph (89–105 km/h)
• Interstates: up to 70 mph (113 km/h)

Speed limits are closely monitored, particularly in construction zones where fines can be significantly higher.

Alcohol limits (DUI laws)

• Legal BAC limit: 0.08% for drivers aged 21 and over
• Under 21: zero-tolerance policy (any alcohol level may result in penalties)

Police often carry out DUI checks during major events such as race weekends.

Seat belts and child safety

• Seat belts are mandatory for all passengers
• Child restraint requirements depend on age, height, and weight
• Non-compliance can lead to fines for both the driver and passengers

Right of way

• Always give priority to pedestrians at crosswalks
• Yield to vehicles already in an intersection
• Pull over immediately for emergency vehicles using lights or sirens

If you are stopped by the police

• Safely pull over to the right as soon as possible
• Stay inside the vehicle, keep your seat belt fastened, and place your hands on the steering wheel.
• Turn on the interior light at night
• Wait for instructions before reaching for documents
• Be prepared to present your driving licence, registration, and proof of insurance

Stay calm and respectful throughout the interaction. If you believe a citation is incorrect, it can be challenged later in court. Signing a ticket only confirms receipt, not guilt.
