Indiana Bureau of Motor Vehicles Permit Practice Test

Before changing lanes, it is crucial to check mirrors and look over your shoulder for blind spots to ensure that it is safe to make the maneuver. This practice helps you to see vehicles that may not be visible in your rearview or side mirrors, particularly those that could be in your blind spot. Checking mirrors allows you to assess the traffic situation around you, while looking over your shoulder gives you a direct line of sight to areas that are not covered by your mirrors. This two-step approach is essential for making informed, safe lane changes and avoiding potential collisions with other vehicles.

For context, signaling your intent without checking could lead to dangerous situations, as you may not be aware of other vehicles in your vicinity. Speeding up before changing lanes increases the risk of losing control or misjudging the distance to other vehicles. Lastly, only checking your left mirror is insufficient, as this ignores traffic that may be present on the right side or in front of you. Overall, the comprehensive approach of checking mirrors and blind spots is the safest way to prepare for a lane change.
