A dead end sign falls under the category of a warning sign. Usually comes in yellow and black color. It is placed on a road to inform drivers that this road has no other route or way. A dead-end sign can be placed in:

• Front point or entry of the road.
• Right side of the road.
• At an intersection.

The most important factor is it should be somewhere in a place where everyone can see them 

Are dead-ends the same as cul-de-sacs?

“Dead-end" and "cul-de-sac" are quite the same. How? Meaning wise both streets don't lead anywhere. However, the difference is how they end. The dead-end street stops suddenly, while a cul-de-sac has a circle for easy turning for a car without a tight u-turn. Let's find out the placement of dead signs to better understand where do I place dead end signs.

Dead End Sign Placement: 

   - The Dead End sign must be placed on the right side of the road just beyond the intersection.

   - It should be posted so drivers can turn at the nearest intersection to avoid the dead end. 

   - Additional Dead End signs can be placed before the end of longer roads.

What are the Legal Requirements for dead-end signs?

As per Section 125a of NYS General Municipal Law, dead-end signs are required on all dead-end roads.

• To mark the actual end of the road, a red diamond Object Marker (OM-4) should be used.
• Before 2007 NYS required Dead End signs to be placed in two locations (near the end of the road and beyond it).
• Right After the updated version of the national MUTCD in 2007, NYSDOT stopped placing signs beyond the end of the road. 
•  The current version of the National MUTCD recommends placing Dead End signs on the right side and using a red marker to mark the road's end.

What is the purpose of Dead end signs?

Several purposes can be served by Dead-end signs. 

• Traffic control: Preventing cars from passing through, dead ends helps keep residential neighborhoods peaceful and reduces unnecessary traffic.
• Safety: They can make neighborhoods feel safer, as there’s less traffic and it's easier to identify unfamiliar vehicles.
• Urban planning: These streets are commonly used in suburban areas to create more private and family-friendly environments.

However, everything comes with its downsides as well, such as increasing travel time for drivers and emergency services, and in some cases, potentially encouraging crime rate by providing secluded spaces.
