When should you signal your intent to turn or change lanes?

• B. At least 30 meters (100 feet) before the turn or lane change
• C. Only when there is a vehicle behind you
• D. Within 50 meters of the turn

Answer: (B)

Signaling your intent to turn or change lanes at least 30 meters (100 feet) before executing the maneuver is important for ensuring the safety of all road users. This advance notice allows other drivers, cyclists, and pedestrians to recognize your intentions and react accordingly. It gives them adequate time to adjust their speed or position, promoting a smoother flow of traffic and reducing the likelihood of accidents.

By signaling well in advance, you provide enough time for those around you to interpret the signal and make informed decisions. This distance gives a clear indication of your upcoming action before it occurs, which is a critical aspect of defensive driving. Being predictable on the road helps maintain safety for everyone involved, and adhering to this practice is a key component of responsible driving behavior.
