How long before you plan to turn must you signal your intention?

Signaling your intention to turn is an essential aspect of road safety and driver courtesy. By indicating your intention in good time, you allow other road users, such as pedestrians and nearby drivers, to anticipate your actions, which helps prevent accidents. The "good time" phrase generally means you should signal well ahead of your turn, typically around 30 meters or at least a few seconds prior, depending on the speed you are traveling. This gives enough opportunity for other road users to react appropriately to your planned maneuver.

Timely signaling also contributes to smoother traffic flow, as it helps maintain the predictability of movement, enabling other drivers to adjust their behavior instead of being caught off-guard. This practice aligns with the overall goal of effective communication on the road, which enhances safety for everyone involved.
