Who has priority when two lanes merge?

The driver of the vehicle in the lane that is ending, is supposed to yield to the vehicles in the other lane. The cars in the lane that is ending should only merge when it is safe to do so. When merging drivers should make sure they have enough space to move their vehicle over into the other lane.

Do you have to indicate when two lanes merge into one?

You must indicate to let others know when you plan to move into another lane. Make sure your indicator is off after you’ve merged or changed lanes.

How do merge lanes work?

In the zipper merge, drivers use both lanes of the highway until the point where one lane ends, and then take turns merging into the single lane – just like a zipper closing. The practice can help make multi-lane highway construction zones safer and help traffic move through a restricted area more efficiently.

What is double lane rule?

Many roads have two or more lanes going in your direction. On two-lane roads, the left lane should generally be used only when you’re passing a slower car driving in front of you; when the road is crowded and both lanes are in use, don’t use the left lane if you’re driving more slowly than traffic.

Do you need to indicate when merging?

It’s not legally required for you to indicate, but it is best practice because other drivers might not have noticed that the lane is merging (i.e. the road is narrowing) and therefore may not be expecting you to move left or right. In an urban area, it’s common for two lanes to merge into one.

When merging onto the freeway from the entrance you should?

Merging from a freeway entrance Use the slip road (on-ramp) to get up to the same speed as traffic on the freeway or motorway as quickly as possible as this gives you more options. When you are travelling at the same speed your entrance will be less disruptive to traffic flow.

What are deceleration lanes?

Deceleration lanes allow traffic exiting a major street to slow down to a safer speed to make a left or right turn at an intersection without affecting the main flow of traffic. These lanes continue a freeway entrance ramp into an additional freeway lane; this becomes an “exit only” lane at the next downstream exit.

Do you have to indicate when merging?

What does it mean when a sign says Lane Ends?

This “Lane Ends” sign often appears in places where a passing lane is eliminated along a rural highway or an entrance lane merges into the main lanes of a freeway. The old version of the sign features two lines running parallel at the bottom with one angling in toward the top.

Is ‘merge in turn’ the correct way to merge lanes?

I’ve long thought that ‘merge in turn’ (not quite sure why RAC have gone with the more American term of zip merging) should be the standard when any lanes merge. It’s known by U.K. drivers as it is occasionally signposted on roads and fits in with our sense of fairness.

What do the lines on a road sign mean?

It is hard to tell, though, whether the lines represent lanes or their borders — if lanes, then it looks like two routes coming closer together (not merging). The existence of text-only supplements (“LANE ENDS MERGE LEFT”) also suggests a graphic-only approach can be baffling.

What does the zipper rule mean for merging lanes?

For instance, the Swedish “Zipper Rule” and British “Double Lanes Merge” signs (below) each show two equal lanes converging. And the issue they address has been on radar of some U.S. transportation professionals for quite a while. The W4-2 tells drivers to merge, but implies priority right-of-way for the lane that continues.
