What is the distance to signal before a turn?

Answer: C — 100 feet

The correct distance to signal before a turn is 100 feet. Signaling well in advance is crucial for maintaining safety on the road, as it alerts other drivers and pedestrians of your intended maneuver. This 100-foot distance allows sufficient time for surrounding vehicles to react appropriately, ensuring a smoother transition during the turn and helping to prevent accidents. In urban areas or places with heavier traffic, this advance notice is especially important to communicate your intentions clearly. While shorter distances may seem adequate, they don't provide enough warning for other drivers or pedestrians, which increases the likelihood of confusion and potential collisions. Therefore, maintaining the 100-foot signaling distance is a critical component of good driving practices in Massachusetts.
