Overtaking is permitted on one-way roads as long as the lanes are separated by dashed lines.

Comprehensive observation during overtaking: Always check the condition of the lane you intend to merge into and the movement of vehicles ahead. Additionally, observe whether the vehicle in front is about to overtake another vehicle before initiating your maneuver.
