Merging Traffic
Join flowing traffic smoothly and safely
Merging onto highways is one of the most demanding driving tasks, requiring speed matching, gap assessment, and coordinated timing. Proper technique makes this safer for everyone.
Why This Matters
Failed merges cause dangerous speed differentials and force sudden braking. Matching speed to traffic and choosing appropriate gaps is critical for safe highway driving.
Key Actions to Take
Use the full length of acceleration lane
Build speed to match traffic flow
Check mirrors and blind spots
Select a suitable gap early
Merge smoothly without hesitation
Do
- Signal your intention early
- Adjust speed to fit the gap
- Make eye contact with other drivers when possible
- Thank drivers who make space with a wave
Don't
- Stop on the acceleration lane
- Merge at slow speed into fast traffic
- Force your way into gaps
- Wait for a "perfect" gap - adjust speed
Pro Tips
Existing traffic should maintain speed - do not slow for mergers
Zipper merge (alternating) is most efficient at lane drops
Practice judging gaps at different speeds
