Lane Ends Sign
The lane ends sign is a diamond-shaped yellow warning sign with a black symbol showing two lanes converging into one, with one lane ending. It warns drivers that the lane they're in or an adjacent lane is about to end and traffic will need to merge. This sign is different from a merge sign — the merge sign indicates traffic entering from a separate road, while the lane ends sign means a lane on your current road is being eliminated. When you see this sign, check which lane is ending (the sign's symbol shows whether the left or right lane ends) and begin merging smoothly. If you're in the lane that's ending, signal early and merge into the continuing lane when there's a safe gap. If you're in the continuing lane, be courteous and make room for merging vehicles. The most efficient technique is the "zipper merge," where drivers use both lanes until the merge point and then take turns. Many drivers merge too early, creating one long line and leaving one lane empty — the zipper merge is actually safer and reduces congestion. Lane endings commonly occur at construction zones, road transitions, and where highways narrow from multiple lanes to fewer lanes.
Rules & What to Do
Identify which lane is ending and plan your merge. Signal and merge smoothly well before the lane ends. If you're in the continuing lane, allow merging vehicles in. Use the zipper merge in heavy traffic — alternate vehicles from each lane at the merge point.
Penalties
No penalty for the warning sign itself. Failing to yield or merge properly can result in a failure-to-yield citation with fines of $100-$250 and 2-3 points on your driving record. Aggressive driving during merges can lead to additional charges.
For Commercial Drivers
Lane ending merges are critical moments for CDL drivers. Signal early and begin your merge well in advance, as large vehicles need more time and space to change lanes. Other drivers may not leave enough room for your vehicle to merge. If your lane is ending, don't wait until the last moment — commercial vehicles can't merge as quickly as passenger cars. Maintain awareness of vehicles in your blind spots.
Frequently Asked Questions
What does the lane ends sign mean?
The lane ends sign warns that one lane on the road is about to end and you'll need to merge into an adjacent lane. Check the sign's symbol to see which lane is ending.
What is a zipper merge?
A zipper merge is when drivers use both lanes until the merge point and then alternate, like a zipper. Studies show it's the most efficient and safest merging method, especially in heavy traffic.
What is the difference between merge and lane ends signs?
A merge sign warns that traffic from another road is entering your road. A lane ends sign warns that a lane on your current road is being eliminated and traffic must merge into the remaining lanes.
