DRIVING SAFETY HANDOUT
The Importance of Lane Discipline & Observing Before Changing Lanes
What is Lane Discipline?
Lane discipline means:
– Staying centered in your lane
– Using the correct lane for your direction and speed
– Changing lanes only when safe and with proper observation
Why is Lane Discipline Important?
1. Prevents Collisions:
Drifting or swerving into another lane without warning can cause side-swipe accidents.
2. Maintains Traffic Flow:
Staying in your lane keeps traffic predictable and flowing smoothly.
3. Improves Reaction Time:
Predictable driving gives everyone more time to react safely.
4. Legal Requirement:
Failing to observe lane discipline can result in penalties or points on your license.
Dangers of Drifting Between Lanes Without Checking
– Blind Spot Collisions: Vehicles may be in areas you can’t see in mirrors.
– Startling Other Drivers: Unexpected moves can cause panic braking or swerving.
– Motorcyclists and Cyclists: Especially vulnerable to sudden lane changes.
– Close Following Vehicles: High speeds reduce the margin for error.
