On a road with only a high-occupancy vehicle lane and no exclusive bus lane, which vehicle may use the high-occupancy vehicle lane?
💡 Hint
To use a high-occupancy vehicle lane, both the occupancy standard and the permitted vehicle type must be met (Annex 1 of the Enforcement Decree of the Road Traffic Act). Count the people actually on board, not the vehicle's seating capacity, and check whether the driver counts.
Answer: ①
Explanation
High-occupancy vehicle lanes may be used by passenger cars and buses carrying three or more people (Enforcement Decree Annex 1). A passenger car with four people qualifies. Even a bus may not use it with too few people on board, a car with two people may not use it, and trucks are not an eligible vehicle type.
