In order to determine the proper distance at which you should signal before making a turn, consider the following options provided:
1. At least 100 Feet in Advance.
2. At least 50 Feet in Advance.
3. When the road is straight.
4. 1 mile before you turn.
Among these options:
- Signaling 1 mile before you turn is not practical because it gives too much advance notice, which may confuse other drivers.
- Signaling when the road is straight is not directly related to the distance before the turn; this condition alone isn't specific enough and does not provide a concrete distance.
- Signaling at least 50 feet in advance may not provide enough time and distance to alert other drivers of your intention, especially in areas with faster traffic or more complex intersections.
Therefore, the best practice and legally required action in many regions is to signal at least 100 feet in advance of your turn. This provides ample time for other drivers to anticipate your actions and react accordingly, ensuring safety and compliance with traffic regulations.
Thus, the correct answer is:
- At least 100 Feet in Advance.
