Merge
The sign indicates that lanes merge and special caution is required.
When You See This Sign
When you see the sign, prepare for lanes to merge. Check mirrors and the blind spot, signal in good time and adjust speed so vehicles can merge safely and smoothly.
Rules & Regulations
- The sign's main purpose is warning and information: it does not change who has the right of way. The existing right-hand rule or other right-of-way regulations continue to apply.
- Adjust your speed so you can let others in or merge yourself without dangerous braking. Keep a safe distance to the vehicle ahead.
- Use your indicators well in advance before changing lanes or merging to make your intentions clear to other road users.
- Avoid sudden lane changes and consider cooperating with other drivers (for example, letting a vehicle merge) to create a smooth and safe merging.
Tips for Drivers
- Begin early by checking your mirrors and blind spot so you won't be surprised during the actual merge.
- Use your indicators early when you plan to change lanes — it helps others make space and reduces the risk of conflicts.
- If traffic is heavy, use the 'every-other-car' principle (zipper merge) to create an even flow and avoid queues.
- Slow down a little rather than making hard braking; a smooth speed adjustment makes merging safer.
Common Mistakes
- Believing the sign gives automatic priority to one lane — the sign does not change who has the legal right of way.
- Changing lanes without signaling or checking the blind spot when traffic begins to merge.
- Braking sharply at the last moment instead of gradually adjusting speed, which creates dangerous situations behind you.

Exam Tip

Did You Know?
The Merge sign is often used before areas where a lane reduction or an on-ramp joins the main carriageway, such as on motorways and major roads, and primarily serves as a warning to increase awareness.
Frequently Asked Questions
Must I let other cars go before me when I see the Merge sign?
Not automatically. You should facilitate and adjust your driving so that a safe merge can occur, but priority is governed by applicable rules and not by the sign itself.
Should I always change lanes immediately when I see the sign?
No. The sign warns that lanes will merge — change lanes only when it is safe and you have signaled in good time.
How should I behave if nobody lets me in at a merge?
Be patient and look for a safe gap. Don't force yourself in and avoid aggressive maneuvers; adjust speed and wait for an appropriate opportunity.
Is the sign found on both motorways and regular roads?
Yes. The sign is used where lanes merge or where on-ramps meet the main carriageway, on both motorways and major roads to warn of an upcoming merge.
