How far (feet) in advance should you activate your turn signal when you intend to turn or change lanes?

• A. 50 ft
• B. 100 ft
• C. 200 ft
• D. 300 ft

Answer: (B)

Giving a signal early gives drivers behind you time to notice and react before you start your move. The standard distance to signal in advance is about 100 feet. This provides a clear warning without signaling too far ahead, which could confuse other drivers about when you’ll actually turn or change lanes. Remember to activate the signal before you begin the maneuver and keep it on until you’re safely through the turn or lane change, then cancel. At typical city speeds, this distance gives roughly a couple of seconds of warning, helping you and others stay safely coordinated.
