↔️ How to Change Lanes Safely
Lane changes are one of the most dangerous maneuvers. Following proper procedure keeps you and others safe.

Step-by-Step Lane Change
S - Signal
Indicate in the direction you want to move. Do this BEFORE checking mirrors - it lets others know your intention.
M - Mirror Check
Check your rear-view mirror and side mirrors. Is there space to move? What's behind you?
O - Over the Shoulder
Quick glance over your shoulder to check your blind spot. This is the only place you'll see motorcycles and cyclists.
S - Shoulder Check Again
Confirm the lane is still clear. Things change quickly!
G - Go
If safe, smoothly steer into the new lane. Cancel your indicator after completing the change.
Blind Spots - Your Biggest Danger
What hides in blind spots:
- • Motorcycles (very easy to miss)
- • Cyclists
- • Small cars
- • Vehicles in your peripheral vision
This is why shoulder checks are MANDATORY, not optional!
When NOT to Change Lanes
- • When someone is already trying to pass you
- • In heavy, stop-start traffic
- • Through an intersection
- • On a curve or hill where visibility is reduced
- • Near a pedestrian crossing
- • When the lane you're entering is ending
- • If you need to cross multiple lanes quickly
Speed and Lane Changes
The Golden Rule:
Match or slightly exceed the speed of traffic in the lane you're entering. Merging into slower traffic causes accidents!
Multi-Lane Changes
Going across multiple lanes?
Do ONE lane change at a time. Complete the first change, settle in that lane, then repeat SMOG for the next lane. Never try to cross multiple lanes in one move.
Pro Tip:
If a car is beside you in your blind spot, you'll see their front tyre, not their door. If you can only see their tyre in your side mirror, assume they're right next to you and don't change lanes.
