I haven't read a driver's manual for years, but yes, as far as I know drivers in Indiana are required to signal before turning.

100 feet
In New Jersey, you should signal your intention to turn at least 100 feet before making the turn. This gives other drivers adequate notice of your actions. Additionally, it's important to use your turn signal continuously until you complete the turn to ensure clear communication with other road users.
