Driving licence tourism on Jeju Island is a recent phenomenon, but it is growing fast. According to the local Driver’s Licence Examination Centre, as of the end of August this year, 2,172 Chinese national had been certified. That’s an average of 62 a week. In 2010, the yearly total was 68.

Quality and cost-effectiveness are huge motivators in this kind of practical tourism. For aspiring Chinese drivers, South Korean licences pay off on both counts. Not only is a trip to Jeju comparable to the cost of China’s big-city driving schools, but it’s also faster and more convenient.

Chinese tour companies offer five-day holidays to get a licence in “South Korea’s Hawaii”. Packages start at around 8,800 yuan ($1,280) and shepherd clients through the process with a bit of sightseeing thrown in. The hotel, driving instruction, on-the-ground transport and testing fees are covered in the price; meals and flights are not. It sounds expensive, but VIP driving course packages in Beijing can run over 15,000 yuan ($2,188) and take months to complete.

China, like many countries, allows valid licences from other nations to be exchanged for a local permit. So once they’ve passed, Chinese residents can convert their South Korean licence by simply passing a written test.

And there’s another reason Chinese tourists feel the Korean licencing process is a better bet. Mingqui Liu, a Chinese student helping his friend schedule a road test, summed it up succinctly. “The Chinese driving test is very strict. The Korean test is easy.”

The process in both nations includes medical checks, written exams, a closed-course driving test and a road test. The Korean version is not necessarily easy—at least, not anymore. In December 2016, the tests were revamped after years of criticism for being too lenient. According to Arirang News, the closed-course test pass rate fell 60% in the immediate aftermath of the changes

But the Chinese version is still notably harder in some respects. The written test, for example, consists of 100 questions versus South Korea’s 40. The scoring is tougher too: China requires a 90% mark to pass, while South Korea allows a more forgiving 60%. (The UK requires 70%.)

There’s also scheduling to consider. Due to limited slots and high demand in China, each step of the test can take weeks to complete. And those who fail any part of the exam more than once must start again from the beginning. On Jeju, meanwhile, it is often possible to complete multiple parts of the exam in a single afternoon.

Yingqin Cui, owner of package-tour company Jeju Island HD Driving School, liaises with a local driving academy to provide the 13 hours of instruction mandated for new drivers in South Korea. This includes four hours on a practise course and six of road driving. She says few people fail to get their licences after this intensive session. “Out of 100 people, maybe one.”
