Traffic changes are taking place ahead, how would you prepare for these changes?

1. You are driving on the right lane, pay attention to the vehicles merging into your lane from the right only.
2. The number of lanes is decreasing; move to the left lane without interrupting the vehicles in that lane.
3. The number of lanes is increasing; stay on the right lane and keep to your right.
4. Correct answer: You are driving in the right lane, pay attention to the vehicles merging into your lane, from left and right.

WhyThe lane layout changes ahead, and cars may merge into your right lane from both the left and the right. Watch both sides.
