When passing on a two-lane road, how many feet ahead should you engage your left signal light in business or residential areas?

Answer: B — 100 feet

When passing on a two-lane road in business or residential areas, you should engage your left signal light at least 100 feet before making the maneuver. This distance provides adequate warning to other drivers and pedestrians, allowing them to anticipate your actions and navigate safely. Signaling well ahead of time is crucial, especially in these areas where traffic can be more unpredictable due to parked cars and pedestrians. Engaging the signal at the correct distance helps to ensure that your intentions are clear and allows for safe merging into the other lane. It is essential to communicate your upcoming move to those around you to enhance safety for all road users. This practice is emphasized in driving regulations to promote thoughtful and responsible driving behavior, especially in areas where visibility may be limited or where there is heavier traffic.
