Introduction
Changing lanes is something drivers do every day, but it’s also one of the most common causes of crashes. A proper lane change requires planning, signaling, checking blind spots, and moving smoothly into the new lane. In this lesson, you’ll learn the safe and correct way to change lanes.
Step-by-Step Procedure
Step 1: Check Traffic
-
Look ahead to make sure traffic is flowing smoothly.
-
Check your rearview and side mirrors to see if the lane is clear.
Step 2: Signal Early
-
Turn on your turn signal at least 3 seconds before changing lanes.
-
This alerts other drivers of your intention.
Step 3: Check Your Blind Spot
-
Do a quick glance over your shoulder in the direction of the lane change.
-
Confirm no vehicles, motorcycles, or cyclists are in your blind spot.
Step 4: Smoothly Change Lanes
-
Maintain a steady speed.
-
Gently steer into the new lane without jerking the wheel.
-
Avoid slowing down suddenly during the maneuver.
Step 5: Cancel Your Signal
-
Once you are fully in the new lane, turn off your signal.
Safety Reminders
-
Never change lanes at intersections — wait until you have passed through.
-
Always yield to vehicles already in the lane you want to enter.
-
Don’t weave in and out of traffic — it’s unsafe and illegal.
-
Increase following distance if traffic is heavy.
Common Mistakes to Avoid
-
Failing to use a turn signal.
-
Not checking blind spots.
-
Cutting off another driver.
-
Drifting between lanes instead of completing the maneuver quickly and smoothly.
Conclusion
A proper lane change is about communication and awareness. By signaling early, checking mirrors and blind spots, and moving smoothly, you can keep yourself and others safe on the road.
