Under New York law, how far before a turn must you signal when driving on a highway at speeds above 40 mph?

1. Fifty feet, a shorter warning distance that does not satisfy the legal minimum
2. Exactly 100 feet and never earlier, regardless of highway speed or traffic conditions
3. Two hundred feet as the fixed legal minimum for every turn on every New York highway
4. At least 100 feet, though more distance is recommended at highway speeds
