Merging Traffic

Join flowing traffic smoothly and safely

Traffic·Medium Risk

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

  1. 01Use the full length of acceleration lane
  2. 02Build speed to match traffic flow
  3. 03Check mirrors and blind spots
  4. 04Select a suitable gap early
  5. 05Merge 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

  • 01Existing traffic should maintain speed - do not slow for mergers
  • 02Zipper merge (alternating) is most efficient at lane drops
  • 03Practice judging gaps at different speeds

Test your judgement

Reading about it is not the same as reacting to it. Try ten real questions.
