Which statement about the statutory speeds for motor vehicles under the Enforcement Rule is NOT correct? (Assume no separate limits set by speed limit signs, etc.)
Legal speeds differ by road type (ordinary roads, automobile roads, expressways), number of lanes and vehicle type (Article 19(1) of the Enforcement Rule). In particular, memorize the numbers in pairs so you do not mix up the maximum and minimum speeds on automobile roads with the minimum speed on expressways.
Answer: ②
Explanation
Under Article 19(1), item 2 of the Enforcement Rule, an automobile road has a maximum of 90 km/h and a minimum of 30 km/h, so a 50 km/h minimum is wrong. Ordinary roads in residential, commercial and industrial areas are limited to 50 km/h, and an expressway with 1 lane each way has a maximum of 80 km/h. On expressways with 2 or more lanes each way, trucks with a load capacity over 1.5 tons are limited to 80 km/h.
