As a rule, you should overtake on the left side. But in the following situations it is also allowed to pass vehicles on the right side:

• Where there are at least two marked lanes in the same direction and the speed limit is 70 km/h or lower.
• When there are at least two marked lanes in the same direction with lane assignment signs indicating different destinations.
• When there are at least two marked lanes in the same direction and there is dense queuing in all lanes.
• If the vehicle in front turns left or if the driver is clearly preparing for a left turn.
• If the vehicle in front is used for road maintenance (for example, asphalt paving or snow ploughing).
