Speed limits in South Korea

In South Korea, speed limits are controlled at the national level by Article 19 of the Enforcement Regulations of the Road Traffic Act, although speed limits can be lowered if deemed necessary, or if they are going through cities, towns, villages, or school zones.

In some cases, the speed on some expressways is limited to 80 km/h, so there are some expressways with speeds that are strictly limited to the level of automobile-only roads such as South Korea's Olympic-daero, Gangbyeon-buk-ro, and Beonyeong-ro.

These speed limits are as follows: Gyeongbu Expressway (Cheonan Junction to Mokcheon IC) Donghae Expressway (Haeundae Viewpoint to Haeundae IC) Muan-Gwangju Expressway (Bukmuan IC to Muan Airport IC) Yeongdong Expressway (Incheon direction Hoengseong rest area to Saemal IC) Jungang Expressway (Chuncheon rest area to Chuncheon TG) Jungang Expressway (Daegam JC Main Line Chuncheon to Busan) Pyeongtaek-Paju Expressway (Sandan IC to Naepo IC) Honam Expressway Branch (Beolgok Service Area to Gyeryong IC) Daegu Outer Ring Expressway (All sections) Gyeongbu Expressway (Cheonan IC ~ Yangjae IC section) Seohaean Expressway (Juknim JC ~ Maesong IC section) Nonsan-Cheonan Expressway Seosan-Yeongdeok Expressway (Dangjin JC ~ Yuseong JC, Cheongju JC ~ Nakdong JC) Jungbu Expressway Second Jungbu Expressway Jungbu Naeryuk Expressway (Nakdong JC to North Yeoju IC) Jungang Expressway (Daegu-Busan Expressway) (Daedong JC to Dongdaegu JC) Seocheon Gongju Expressway (Seocheon Tunnel ~ Seogongju JC) Speed limits in most areas are enforced exclusively by speed cameras instead of police officers.

There is a tolerance of 10 km/h over the posted limit and reduced fines for exceeding the limit by 11 - 20 km/h.

Because of this, many Korean drivers consider the limit to be 11 km/h above the posted limit, meaning that a speed limit of 110 km/h may be treated as a speed limit of 121 km/h.
