Under what condition are you allowed to pass another vehicle on the left?

Passing another vehicle on the left is typically allowed in specific circumstances, and one such condition is when the other vehicle is stationary and there is a block in the road. This situation may arise when a vehicle is stopped due to traffic congestion or waiting for a signal, and it is safe and legal to safely maneuver around it on the left side.

This kind of scenario provides a clear path for the driver to pass while ensuring the safety of all involved. It's essential to confirm that the left side is clear, and there are no other vehicles or obstacles that could pose a danger while executing this maneuver.

Other conditions like having no traffic or police instructions may not specifically pertain to passing on the left. Passing at traffic lights typically depends on the signal's current state, and in most situations, drivers are expected to obey the red light, making passing risky and potentially illegal. Safety is paramount in all driving situations, and understanding when and how to pass legally and safely is essential for all road users.
