What must you remember when you want to change lanes?

When changing lanes, it's crucial to signal your intention in advance to inform other drivers of your plans. This is aligned with the German traffic rule that emphasizes the importance of using indicators for safety and communication on the road. Additionally, paying attention to the traffic behind you is vital to ensure that you do not cut off other vehicles or create dangerous situations.

Braking heavily before changing lanes is unnecessary and can be hazardous, as it may confuse other drivers and increase the risk of accidents. Therefore, proper signaling and being aware of surrounding traffic are essential to executing a safe lane change according to German driving regulations.
