What applies when you see this traffic sign?

The traffic sign you're encountering indicates that you're on a multi-lane road.

1. You may choose any lane that suits your direction of travel, allowing for flexibility based on traffic conditions and your intended route.
2. It's important to note that while you can drive more quickly in the right-hand lane, you should also consider the speed limits and flow of traffic. The left lane is typically used for overtaking, where vehicles may be traveling at higher speeds.

However, the statement about driving faster than 50 km/h is misleading; there's no specific minimum speed of 50 km/h required on multi-lane carriageways unless explicitly stated by additional signs. Always adhere to the speed limits posted and adjust your speed according to road conditions.

Understanding these rules is crucial for safe driving, ensuring you maintain proper lane discipline and respect the flow of traffic.
