Final answer:
The correct distance for signaling before a turn depends on local traffic laws, which vary by location. Signaling well in advance is generally advised for safety. Option 1 is correct.
Step-by-step explanation:
The question is regarding the proper distance for signaling a turn before changing directions while driving. Each state or country may have different laws about the minimum distance for activating turn signals. However, based on this information, a specific distance is not provided.
To answer the question accurately, one would need to reference the local traffic laws or the driver's manual for the specific jurisdiction in question, as this information tends to vary by location.
For the purposes of safety and allowing other drivers to anticipate your actions, it is generally advised to signal well in advance of your turn. The distances mentioned, such as 50 feet, 75 feet, 100 feet, or 125 feet, may be specific to certain regions' driving regulations.
If we consider Bridget's observation of cars taking 3 seconds to travel 50 meters, a driver moving at similar speeds would likely need to signal at least a few seconds in advance to cover a safe turning distance.
