How far in advance should you signal before turning or changing lanes?

  1. At least 50 feet

  2. At least 100 feet

  3. At least 150 feet

  4. At least 200 feet

The correct answer is: At least 100 feet

Signaling at least 100 feet in advance before turning or changing lanes is essential for ensuring the safety of all road users. This distance provides ample time for other drivers and pedestrians to notice your intentions and react accordingly. It helps in maintaining smooth traffic flow and minimizes the risk of accidents caused by sudden lane changes or turns. The 100-foot guideline is also in alignment with typical driver perception and reaction times. By signaling adequately, you're allowing other road users to adjust their speed and position as necessary, thereby contributing to a safer driving environment. This is especially crucial in urban settings where pedestrians and cyclists may also be present. Understanding this practice not only aids in compliance with traffic laws but also reinforces defensive driving techniques that prioritize the safety of all road users.
