Merging from an acceleration lane
Practical advice on speed, observation and positioning when merging onto motorways and expressways.
Using the acceleration lane correctly is all about timing. You need to build speed early, read the traffic from behind and be ready to adjust both your position and your pace before the lane ends.
What you need to know
- The acceleration lane is designed so you can match the speed of traffic in the main lane.
- You must use mirrors, side mirrors and a shoulder check systematically before moving the car.
- It is better to make clear speed choices early than small hesitant adjustments late.
Typical situations
| Situation | What you should do | Common mistake |
|---|---|---|
| Light traffic on the motorway | Build speed steadily and find a natural gap early. | Joining at too low a speed and forcing others to brake. |
| Heavy traffic | Read the rhythm of the main lane and adjust your speed to fit into a gap. | Staring at the car beside you instead of reading several vehicles ahead. |
| Short acceleration lane | Prioritize quick speed adjustment and early observation. | Waiting too long before accelerating. |
Common mistakes
- Taking too long to decide which gap to use.
- Forgetting the shoulder check before actually merging.
- Assuming traffic in the main lane will always move for you.
