You are driving in lane 2 of a road with two lanes in each direction and want to move into lane 1. Another vehicle is approaching normally from behind in lane 1, and changing lanes now could obstruct its normal travel. What is the most appropriate action?
💡 Hint
You must not change lanes if it may obstruct the normal passage of a vehicle coming from the direction you want to move into (Article 19(3) of the Road Traffic Act). A turn signal or horn only informs others and gives you no priority, and sudden braking without unavoidable cause is also prohibited (Article 19(4)).
Answer: ③
Explanation
Under Article 19(3) of the Road Traffic Act, you must not change lanes if it could obstruct the normal travel of a vehicle coming in the lane you want to enter. Turning on the signal does not remove this duty. Sudden braking without a need to prevent danger is also prohibited by paragraph 4 of the same article, so option 4 is wrong as well.
