Korea Road Trip Guide: How to Drive Safely & Rent a Car

Unlocking the Open Road: Your Complete Guide to Driving in Korea

So, you are planning a trip to the Land of the Morning Calm and thinking about getting behind the wheel? I get it. While our public transport system—from the KTX to the Seoul Metro—is world-class(For information about Seoul’s bus and taxi systems, see here.), there is a specific kind of freedom that comes with driving in Korea. It’s the only way to chase sunsets along the coastal roads of Gangwon-do, discover hidden Hanok cafes in the countryside, or navigate the volcanic landscapes of Jeju Island on your own schedule.

However, as a local who sees travelers struggle with this every day, I have to be honest: driving here is an adventure. It requires preparation, a bit of patience, and the right knowledge. From the critical paperwork to navigating our unique toll system, I’ve compiled everything you need to know to hit the road safely.

The Holy Trinity: Documents You Must Have

You cannot simply arrive at Incheon Airport and expect to rent a car with just your home country’s license. Korean rental agencies are strictly regulated. To pick up your keys, you must present all three of the following items physically (no digital copies):

• 1. Valid Driver’s License: Your original license from your home country. It must be valid for the entire rental period.
• 2. International Driving Permit (IDP): This is non-negotiable. South Korea is a member of the Geneva Convention on Road Traffic (1949) and the Vienna Convention (1968). Your IDP must be issued by a member country of these conventions. ⚠️ Critical Warning: You must obtain your IDP in your home country before you travel. You cannot get one after arriving in Korea. Also, ensure the spelling of your name on the IDP matches your passport exactly.
• 3. Passport: Used for identity verification.

If you are planning to stay long-term, you might be able to exchange your foreign license for a Korean one, but for short-term travelers, the IDP is your golden ticket.

The Rental Process & Insurance: Before You Book

Booking a car here is straightforward, but there are a few “unwritten rules” and requirements you should know to avoid awkward moments at the counter.

Age and Credit Card Requirements

Generally, you must be at least 21 years old and have held your license for at least one year to rent a compact car. For larger sedans or SUVs, many companies require you to be over 25. Furthermore, the main driver must present a physical credit card (not a debit card) in their own name for the deposit.

Understanding Insurance (CDW)

Korean roads can be narrow, and parking spaces are notoriously tight. While basic insurance is usually included, I strongly recommend upgrading to the Collision Damage Waiver (CDW) with zero deductible (often called “Super Insurance” or similar). It offers peace of mind against scratches and dings, which are common in busy areas.

Navigating Toll Roads and the Hi-Pass System

South Korea has an extensive network of expressways, but most of them are not free. We use a toll system, and understanding how to pay is crucial to avoid fines.

The “Hi-Pass” (하이패스) System

You will see blue lines painted on the road leading to toll gates. These are for cars equipped with a Hi-Pass device (an electronic toll collection system).

• If your rental has Hi-Pass: You can drive through the blue lanes without stopping. The device will “beep,” and the toll is recorded. You usually settle the total amount with the rental company when you return the car.
• If your rental DOES NOT have Hi-Pass: You must avoid the blue lanes. Stick to the lanes marked for “Cash/Card.” You will either take a ticket (entry) or pay the toll (exit). Most toll gates accept credit cards (including foreign Visa/Mastercard) and T-Money cards.

Crucial Traffic Rules & The “Right Turn” Law

We drive on the right side of the road (steering wheel on the left), similar to the US. However, enforcement here is automated and strict. Here is a breakdown of what you need to watch out for.

Speed Limits & Cameras

Speed cameras are everywhere—fixed boxes, average speed zones, and mobile police units. Rely on your GPS for warnings.

Road Type	Typical Speed Limit	Notes
Expressways	100 km/h – 110 km/h	Strictly enforced by cameras.
Urban / City Roads	50 km/h (Safe Speed 5030)	Standard city limit.
School Zones	30 km/h	Extremely Strict. Fines are doubled.

The “Right Turn on Red” Rule

This is the most confusing rule for foreigners because it changed recently. Yes, you can turn right on red, BUT you must come to a complete stop first.

1. If the pedestrian light is GREEN: You must wait until it turns red and the crosswalk is clear.
2. If the traffic light is RED: Stop completely at the line, check for pedestrians, and then proceed slowly.
3. When in doubt, just wait. It is safer to be honked at than to break the law.

⚠️ Zero Tolerance for DUI: South Korea has one of the strictest drunk driving laws in the world. The limit is 0.03% BAC. This is effectively one shot of Soju or a small beer. Penalties include immediate license cancellation and massive fines. If you drink, take a taxi. Period.

Survival Guide: Navigation Apps (Forget Google Maps!)

I cannot stress this enough: Do not rely on Google Maps for driving in Korea. Due to local security laws regarding map data export, Google Maps does not offer turn-by-turn navigation here.

To survive, you must download one of the following apps before you arrive:

• Naver Map (Recommended): Offers a great English interface, reliable real-time traffic data, and precise toll cost calculations.
• Kakao Map: Also excellent and widely used by locals.

Your rental car will likely have a built-in GPS, but it might be in Korean. Mount your phone, use Naver Map, and follow the voice instructions. It will even warn you about speed bumps and cameras!

Local’s Verdict: When to Drive vs. Take the Train

Just because you can drive doesn’t always mean you should. Here is my honest advice on when to rent a car versus relying on our fantastic public transit.

❌ Skip the Car in Seoul & Busan: Traffic in major cities is intense, parking is expensive and scarce, and the subway is faster. A car in Seoul is a liability, not an asset.

✅ Rent a Car for Jeju & Gangwon: This is where driving shines. Jeju Island is nearly impossible to explore fully without a car. Similarly, the mountainous regions of Gangwon-do or the historic villages around Andong are best experienced with your own vehicle.

Driving in Korea offers a unique window into the culture—from rest stop snacks (try the Walnut Cakes!) to the courtesy of hazard light “thank yous.” Drive safe, respect the rules, and enjoy the ride!
