When changing lanes on a multi-lane road, which lanes should you check?

When changing lanes on a multi-lane road, it is essential to ensure that you check both the lane next to you and the far lane. This practice is crucial for several reasons. First, checking the lane next to you allows you to see if there are any vehicles that might be in your blind spot or if another driver is also intending to change lanes. This helps maintain safety by avoiding potential collisions.

Additionally, looking at the far lane can provide you with information about oncoming traffic and allow you to gauge the speed and position of vehicles that may be in that lane. This broader awareness of your surroundings is vital to making well-informed decisions about when it is safe to change lanes. By considering both lanes, you enhance your situational awareness and decrease the likelihood of accidents. Therefore, checking both adjacent lanes is the best practice.
