How many feet must a driver signal before making a turn in Iowa?

In Iowa, a driver is required to signal at least 100 feet before making a turn. This rule is in place to ensure that other drivers and pedestrians are aware of the driver’s intention to turn, promoting safety and reducing the potential for accidents. Signaling well in advance gives sufficient time for others to react, especially in busy traffic situations or when pedestrians are present.

The requirement for 100 feet allows for a clear and consistent communication of a driver's intentions, which is critical for maintaining the flow of traffic and ensuring the safety of all road users.
