What Does SMILE Mean in Driver Education?
National Driver Training uses the word SMILE to help new drivers remember important checks before every trip.
Quick answer: SMILE stands for Seat Position, Mirrors, Interior, Lock Doors and Windows, and Everybody Buckle Up. Use the reminder before beginning a lesson or everyday drive.
S — Seat Position
Adjust the seat so the driver can operate the accelerator and brake comfortably and maintain good control of the steering wheel. NDT’s checklist calls for at least 10 inches between the driver’s upper body and steering wheel where the vehicle’s setup allows; follow the vehicle manufacturer’s seating and airbag guidance.
M — Mirrors
Adjust both exterior mirrors to help reduce blind spots and set the inside mirror to show the full rear window where possible. Know that mirror settings do not eliminate every blind spot.
I — Interior
Clear loose items that block the windshield or rear-window view, set a comfortable temperature, turn off the radio during instruction and silence and stow phones. Keep the cabin free from avoidable distractions.
L — Lock Doors and Windows
Secure the vehicle’s doors and manage windows before the drive. NDT emphasizes keeping doors locked and windows appropriately secured to reduce distractions and support passenger safety. Follow the vehicle’s instructions and any applicable child-safety precautions.
E — Everybody Buckle Up
Confirm that the driver and all passengers wear properly fitted seat belts. Children also need age- and size-appropriate restraints under applicable law. No one should ride unbuckled.
How can you remember SMILE during a first lesson?
Ask the new driver to say each letter aloud before starting. Repeat the sequence until it becomes a habit, then check the surroundings before shifting into gear.
