When must you signal before turning?

Signaling before making a turn is crucial for ensuring the safety of all road users. The correct answer is that you must signal at least 100 feet before the turn. This distance provides adequate time for other drivers, cyclists, and pedestrians to be aware of your intention to change direction. By signaling well in advance, you are giving others a chance to react and adjust their own movements, which helps reduce the risk of accidents.

The requirement to signal 100 feet in advance is based on the understanding that it is a standardized distance that balances visibility and reaction time. The law aims to create a safer driving environment by ensuring that drivers communicate their intentions clearly and in a timely manner. Depending on road conditions, speed, and traffic, signaling too late may not provide sufficient warning to those around you, potentially leading to dangerous situations.

In contrast, shorter distances may not give other road users enough time to respond appropriately, while longer distances might be unnecessary in situations where vehicles are closer together or the speed is lower. Therefore, 100 feet is recognized as an effective guideline for safe signaling before turning.
