Is it allowed to change lanes to the right?

[VanEmerson]

It is allowed to change lanes to the right. Techniques for changing lanes to the right: One light, two mirrors, three steering. First, you must turn on the turn signal before changing lanes; second, observe the vehicles ahead and behind to ensure a safe distance; third, steer gently and change lanes quickly. If you want to change lanes, you must turn on the turn signal at least three seconds in advance to alert other vehicles. Before changing lanes, observe and judge through the interior and exterior rearview mirrors, checking the traffic conditions behind, beside, and in the lane you intend to change into. Sign for changing lanes to the right: All vehicles must turn right only; this sign is generally placed at intersections where vehicles must turn right.
