Who have the right away when passing?

When passing another vehicle, the driver in the left lane has the right of way, provided they are legally allowed to do so. The driver being passed must maintain their speed and position without encroaching on the lane of the passing vehicle. Additionally, it’s essential for both drivers to follow local traffic laws and signals, which may dictate specific rules regarding passing. Always prioritize safety and ensure that the maneuver can be completed without endangering any road users.
