What is advised before making a lane change?

Before making a lane change, it is essential to turn on your left or right signal and check your mirrors. Signaling your intention to change lanes alerts other drivers of your upcoming maneuver, which enhances safety for everyone on the road. This communication is crucial in maintaining awareness among drivers and avoiding potential accidents.

Checking your mirrors allows you to assess the surrounding traffic conditions. This includes observing if there are vehicles in your blind spots or if the lane you wish to enter is clear. These two actions combined—signaling and checking mirrors—help ensure that you make a safe lane change, reducing the risk of collisions.

Using the horn or speeding up can create confusion and increase the likelihood of accidents, while only looking in the rear-view mirror does not provide a complete picture of the traffic situation. Therefore, the combination of signaling and mirror checks is the correct approach for safe lane changes.
