You are driving a passenger car on an expressway with 2 lanes in each direction (not a section specially designated by the Commissioner General of the National Police Agency). It is raining and the road surface is wet, and there are no variable speed limit signs. What maximum speed must you observe?
💡 Hint
In bad weather, reduce the maximum speed by 20/100 when the road is wet from rain or there is a little snow, and by 50/100 for ice, visibility within 100 meters, or heavy snow (Article 19(2) of the Enforcement Rule). First recall the basic maximum speed for a passenger car on this road, then calculate.
Answer: ③
Explanation
Under Article 19(1) of the Enforcement Rule, the maximum speed for passenger cars on an expressway with 2 or more lanes each way is 100 km/h. Paragraph 2, item 1 requires reducing the maximum by 20/100 when rain has wet the road, giving 80 km/h. 50 km/h would apply where a 50/100 reduction is required, such as an icy road or visibility within 100 meters.
