When is it unsafe to pass another vehicle on the road?
It is unsafe to pass another vehicle on a curve where your view is blocked because you cannot see oncoming traffic. This lack of visibility increases the risk of a head-on collision, making such maneuvers highly dangerous. The law requires a clear view of the road ahead before attempting to pass safely.
