When a driver is **dazzled** by another vehicle traveling in the opposite direction, their ability to see the road is affected due to the excess light in their eyes. In this situation, it is crucial to **reduce speed** to maintain control of the vehicle and ensure safety. If necessary, a **complete stop** of the vehicle should be made, always taking appropriate safety precautions, such as not moving into other lanes when reducing speed or stopping.


This measure is important because it allows the driver to regain visibility and avoid potential accidents. Additionally, following the right edge line of the road can help maintain orientation while reducing speed or stopping the vehicle.
