What must you do when you see a yield sign?

When you see a yield sign, the correct action is to slow down and prepare to stop for traffic. This sign indicates that you must give way to other road users, which means you need to assess the situation and determine whether it is safe to proceed.

By slowing down, you can better evaluate the traffic conditions, ensuring that you do not enter an intersection or merge into another lane without yielding to oncoming vehicles or pedestrians. This action promotes safety by allowing you to respond appropriately to any surrounding vehicles that may have the right of way.

The other options suggest actions that do not align with the purpose of a yield sign. Coming to a complete stop may be unnecessarily cautious unless it is required for safety, as yield signs allow for the possibility of proceeding if the way is clear. Continuing at the same speed fails to acknowledge the need to evaluate other vehicles' movements. Speeding up to merge with traffic could create dangerous situations, especially if there is insufficient space or if other vehicles are not expecting you to accelerate instead of yield. Thus, slowing down and being ready to stop helps maintain safety and proper traffic flow.
