In Idaho, how many vehicles must be delayed for a vehicle to be required to turn off the road to allow others to pass?

In Idaho, a vehicle is required to turn off the road to allow others to pass when there is one or more vehicles delayed behind it. This regulation aims to enhance traffic flow and ensure safety, particularly on roads where passing lanes are not available. By creating this requirement for only a single delayed vehicle, it encourages drivers to be considerate of those behind them, promoting smoother navigation and reducing frustration for all road users. This approach reflects a broader traffic safety principle emphasizing the importance of maintaining an efficient driving environment.
