When merging onto a road using an **acceleration lane**, it is essential to follow the **R.S.M. safety rule**. This rule indicates that before performing any maneuver, such as entering a road, you must **observe** and **ensure** that you do not pose a danger to other drivers. Additionally, you need to **signal** your intention to merge, either with your arm or with the vehicle's lights.

When entering a road from an acceleration lane, it is crucial to **yield** to vehicles already traveling on the road. This means you should not be an obstacle or cause danger to approaching vehicles. If necessary, you must stop at the beginning of the acceleration lane until it is safe to merge.

Although drivers on the road are obliged to facilitate the merging of other vehicles, especially in the case of large vehicles like buses, the primary responsibility lies with the merging driver. They must ensure that the maneuver is performed safely and without interfering with existing traffic.
