Delineators and fixable posts are traffic control devices used to enhance visibility, guide drivers, and promote safety on roads and highways. They are typically made of durable materials such as plastic, rubber, or metal and are designed to withstand various weather conditions.

Delineators are vertical markers that are placed along the edge of the roadway or in the center to define the boundaries of the traffic lane. They come in various shapes, including cylinders, tubes, or panels, and are often reflective to increase visibility during low-light conditions. Delineators help drivers maintain their lane position, especially in areas with poor visibility or during nighttime driving. They also serve as a visual guide in areas prone to fog, snow, or heavy rain.

Fixable posts, on the other hand, are sturdy vertical supports that are permanently or semi-permanently fixed into the ground. They are commonly used for applications such as road signage, traffic signal support, or as barriers to separate lanes or restrict access. Fixable posts are designed to withstand impacts from vehicles and remain in place, ensuring the stability and integrity of the traffic control system.

Both delineators and fixable posts play an important role in road safety by providing visual cues and guidance to drivers. They help improve lane discipline, prevent lane encroachments, and reduce the likelihood of accidents. By increasing visibility and clearly marking the roadways, these devices contribute to a smoother and safer flow of traffic.
