What does the white rectangular marking box mean?

[ElianaRose]

The white rectangular marking box indicates a yield line, typically placed 5-30 meters before the stop line at intersections of non-main roads. It signals drivers to slow down and yield the right-of-way to vehicles on the main road. The yield line requires drivers to reduce speed or stop, observe traffic conditions on the main road, and proceed only when it is safe to do so, ensuring priority for vehicles on the main road. At intersections marked with yield lines, vehicles must come to a complete stop and yield to vehicles on the main road. This marking is usually used in conjunction with a "Yield" sign. The yield line consists of two parallel dashed lines and an inverted triangle, all in white. Deceleration markings often appear at exit ramps, toll plaza areas, or other sections where vehicles need to slow down. They can be categorized into transverse deceleration markings (perpendicular to the direction of travel) and longitudinal deceleration markings, which may appear as single, double, or triple dashed lines. Transverse deceleration markings are a series of parallel white dashed lines designed to alert drivers to reduce speed.
