Step-by-step explanation:
The correct answer is 100 feet.
According to most state laws in the United States, when driving at a speed limit of 50 mph or greater, you must give turn signals at least 100 feet before turning or changing lanes. This distance provides enough time for other drivers to react and adjust their speed accordingly.
For example, if you are driving at 50 mph and you suddenly turn without giving a signal, the driver behind you might not have enough time to brake or change lanes, which can result in a rear-end collision.
