A common trap is treating the amber arrow as optional advice. Learners might think they can stay in the lane if they're in no hurry. However, the sign mandates a lane change, so the correct action is always to prepare to move when safe. Another mistake is changing lanes too late or abruptly, which is unsafe.
If there are multiple amber arrows pointing to different lanes, you must follow the instruction for the lane you are in. The arrows are specific to each lane. If you are in a lane with an amber arrow, you must move to the lane indicated by that arrow.
