Driving Requirements
South Korean law requires foreign visitors to carry a valid IDP alongside their original home-country license. The home-country license alone is generally not sufficient for legal driving. The IDP must be issued under the 1949 Geneva Convention and is recognised for up to one year from your date of entry into South Korea. Some nationalities may alternatively use a notarised Korean translation of their license in place of an IDP, verify your country's specific arrangement with the Korean Embassy before travelling.
South Korean law sets the legal minimum driving age at 18. Separately, rental companies impose their own minimums, which vary by provider, many require drivers to be at least 21, and some restrict certain vehicle classes to drivers 25 or older. Confirm directly with your chosen company. Young-driver surcharges for drivers typically under 25 or 26 are a rental company policy, not a legal requirement.
South Korean law requires all vehicles to carry third-party liability coverage for personal injury and property damage. Rental vehicles must legally include this baseline coverage. Rental companies typically offer additional products on top of the legal minimum, such as collision damage waiver (CDW) and personal accident insurance, which are optional under law but recommended if your travel insurance or credit card does not cover rental-vehicle damage. Treat the mandatory component as a legal floor, not full protection.
Most rental companies in South Korea require a credit card (not a debit or prepaid card) at pickup to authorise a security deposit. The hold amount varies by provider and vehicle class. Some companies will decline pickup if only a debit card is presented. Confirm card type, deposit amount, and release timeline with your chosen provider before arrival, as these are company policies with no single standard.
Traffic in South Korea travels on the right. Unlike North America, turning right at a red light is generally not permitted unless a dedicated right-turn arrow signal or posted signage explicitly allows it, a common catch for North American drivers. South Korea's legal blood alcohol limit of 0.03% is stricter than in many Western countries, and speed and red-light cameras are densely deployed across Daejeon's urban roads and the expressway corridors that converge there.
Helpful Tips
Daejeon has no commercial airport of its own, so skip the airport pickup entirely, collect your rental directly from offices near Daejeon Station (the city's KTX hub) rather than hauling a car from Cheongju Airport (CJJ, roughly 45 minutes away) or from Incheon (ICN), which adds hours of highway driving before you even begin.
Before signing off on the vehicle, photograph every panel and document all existing marks on the rental company's inspection sheet; Korean rental companies typically bundle basic CDW into the rate. But the deductible waiver is usually a separate upgrade, whether that upgrade is worth it varies by company, so read the excess amount rather than assuming full coverage.
Do not rely on Google Maps for driving navigation in Daejeon: South Korean regulations restrict the map data that Google can use for turn-by-turn routing, making directions unreliable on local roads. Install Naver Map (네이버 지도) or Kakao Maps (카카오맵) instead, both offer an English-language mode, accurate lane guidance, and real-time traffic for Daejeon's expressway interchanges.
Confirm your rental car's fuel type at pickup, gasoline (휘발유), diesel (경유), and LPG are all common in Korean rental fleets, and LPG vehicles require dedicated LPG pumps that are less widespread than standard petrol stations. The standard arrangement is full-to-full; prepaid fuel options exist at some companies but are not universal, so clarify this before leaving the lot.
Parking is generally manageable in Daejeon's Dunsan-dong district (the main business and government area), where underground garages beneath major department stores and public buildings offer reliable paid spots, including overnight. Avoid trying to street-park in the narrow lanes of older commercial zones like Eunhaengdong during daytime hours, as enforcement is active and spaces disappear quickly.
Driving Warnings
South Korea's 'Minsik's Law' (2020) imposes criminal penalties, not just fines, for accidents in school zones: up to 3 years imprisonment and fines up to 30 million won. All school zones are limited to 30 km/h and equipped with 24/7 speed cameras, so treat these limits as absolute regardless of traffic conditions.
Turning right on a red light is illegal by default in South Korea, unlike North America and many other countries, a right turn is only permitted when a dedicated green arrow or supplementary signal explicitly allows it. Intersection cameras capture violations automatically and rental drivers often receive fine notices after returning home.
South Korea's drunk-driving BAC limit is 0.03%, roughly half the threshold in many Western countries, meaning a single drink can legally impair your right to drive. Police conduct random checkpoint stops, on weekend evenings in entertainment-heavy areas such as Dunsan-dong, Daejeon's main commercial district.
Urban speed limits across Daejeon were reduced to 50 km/h on most city roads following South Korea's 2021 national policy change, with fixed speed cameras common on arterial roads and near the Dunsan government complex area. Navigation apps announce fixed camera locations. But mobile enforcement units operate without warning and issue fines that follow the registered vehicle owner.
