Effortless Car Rentals at Gwangju Airport (KWJ)

Yes, but you'll need an International Driving Permit (IDP). Your US license alone is not sufficient. The IDP must be issued in your country of residence and accompanied by your original license. Processing takes about 10-15 minutes at AAA offices in the US ($20). Without an IDP, you risk fines of 100,000-200,000 KRW ($75-$150) if stopped by police.

Highway tolls in South Korea are paid via the Hi-pass system, which uses dedicated electronic lanes. Most rental cars come with a pre-installed Hi-pass device (rental fee: 2,000-3,000 KRW/day, ~$1.50-2.25). Alternatively, you can use Cash lanes and pay manually. For trips over 100km on expressways, Hi-pass saves significant time—tolls average 20,000-40,000 KRW (~$15-30) per journey. Credit card payment is also accepted at manual booths.

Most Korean rental companies charge a young driver surcharge for drivers under 25. Expect to pay an additional 10,000-20,000 KRW per day (~$7.50-$15). At major agencies like Lotte Rent-a-Car or AJ Rent-a-Car, the surcharge is typically 15,000 KRW/day for drivers aged 21-24. Some companies offer promotions that waive this fee for longer rentals (7+ days). Book early and compare—rates vary significantly between agencies.

Korean vehicles run on gasoline (gasoline) or diesel. Approximately 60% of passenger cars use gasoline. Gas stations are abundant nationwide, with about 12,000 stations across South Korea—roughly one every 5-10km on major highways. Most operate 24/7. Rental cars usually come with a full tank; return it full to avoid refueling charges. unleaded gasoline (benzine) costs approximately 1,700-1,900 KRW/liter (~$1.25-1.40/gallon).

Gwangju itself rarely gets heavy snow, but mountainous routes toward Jeollanam-do or if heading north toward Seoul (via Honam Expressway) can see icy conditions December through February. Snow tires are mandatory on expressways during winter months—you'll be fined 60,000 KRW (~$45) if caught without them. Most rental companies offer winter tire packages for 10,000-15,000 KRW/day. If visiting between December-February, explicitly request winter tires when booking, especially for early morning/evening travel.

Yes, turning right on red is prohibited throughout South Korea unless there is a specific green arrow signal indicating it's allowed. This surprises many US drivers. Running a red light results in a fine of 60,000-100,000 KRW (~$45-$75) plus 6 penalty points on your license. Also note: Korean drivers frequently run yellow lights, so don't assume a yellow means you have the right of way. Left-hand traffic means roundabouts (rotaries) are common—vehicles already in the rotary have priority, and you must yield to traffic already circulating.
