Plastic poles, also known as bollards, are placed on roads to prevent vehicles from entering the wrong lane or from colliding with pedestrians or buildings. While they can be run over without causing major damage to a vehicle, doing so is illegal in some places, with fines of up to $165. Plastic poles are a cheap and effective way to calm traffic, with studies showing that they can reduce excessive speeding and encourage drivers to yield to pedestrians.

What You'll Learn
Plastic poles are a cheap and effective traffic-calming solution
Plastic poles, also known as bollards, are a cheap and effective solution for traffic calming. They are placed several feet into the roadway to narrow traffic lanes and slow down speeders. These poles are usually made of plastic, and despite their appearance, they are not made of metal or concrete. While they can be run over, they typically do not cause major damage to vehicles.
The installation of plastic poles has been shown to reduce excessive speeding. A study in Milwaukee found that excessive speeding over 40 miles per hour was reduced by up to 40% in the presence of plastic poles. The same study also found that six times as many drivers yielded to pedestrians at crosswalks when bollards were present.
Plastic poles are particularly effective in areas with high crash rates, as they help to control road traffic and prevent vehicles from colliding with pedestrians or structures. They are also useful in preventing "lane diving", where drivers dangerously switch between express lanes and regular lanes.
While plastic poles are a cost-effective solution, they typically only last about three to five years. As a more permanent solution, concrete curb extensions are more effective at preventing reckless driving due to their larger physical barrier. However, plastic poles and street paint are a much more affordable option, costing about a quarter of the price.
In summary, plastic poles are a cheap and effective solution for traffic calming, particularly in areas with high crash rates. They help to reduce speeding and improve pedestrian safety. While they may not be as durable as concrete curbs, they are a more affordable option for improving road safety.

They are placed to prevent lane diving
Plastic poles are placed on roads to prevent lane diving. Lane diving is the practice of drivers switching lanes illegally, which can cause accidents, especially at high speeds. These poles are placed to keep drivers in their respective lanes. They are also known as bollards, which are sturdy, short, vertical posts.
In 2016, the Florida Department of Transportation installed sturdier plastic poles with narrower gaps to discourage drivers from diving into lanes they are not supposed to be in. These poles separate the I-95 express lanes from the general lanes in Miami-Dade and Broward counties. While these poles can be run over without causing major damage to a vehicle, there is a minimum fine of $165 for violating the poles to enter or exit express lanes.
Plastic poles are also placed at intersections to slow down speeders by narrowing traffic lanes. They have proven to be a cheap and effective traffic-calming solution, reducing excessive speeding and increasing the number of drivers yielding to pedestrians. While concrete curbs are considered a more effective barrier, plastic poles are a much cheaper alternative.

They are not indestructible and can be run over
Plastic poles are being used to separate lanes and prevent drivers from entering the wrong lane. These plastic poles are not indestructible and can be run over, usually without causing major damage to the vehicle.
In 2016, the Florida Department of Transportation installed sturdier plastic poles with narrower gaps to discourage drivers from diving into lanes they are not supposed to be in. Despite this, the poles are prone to being damaged and completely broken. When this happens, gaps between the poles allow drivers to dangerously move between express lanes and regular lanes, a practice known as "lane diving," which can cause accidents at high speeds.
Electronic signs over the highway warn drivers not to drive over the plastic poles, with a minimum fine of $165 for violating the poles to enter or exit express lanes. While the plastic poles are intended to keep drivers in their respective lanes, some observers argue that they are ineffective and can be run over.
Plastic poles are also used at intersections to slow down speeders by narrowing traffic lanes and shortening crossing distances for pedestrians. This type of infrastructure is a cheap and effective solution for traffic calming, reducing excessive speeding and increasing yielding to pedestrians. However, concrete curbs are considered a more effective barrier but are more costly to install.
In conclusion, while plastic poles serve an important purpose in traffic control and lane separation, they are not indestructible and can be run over. It is important for drivers to follow the designated lanes and avoid running over the plastic poles to ensure their safety and comply with the law.

They are placed at designated points to separate express lanes from general lanes
Plastic poles are placed at designated points to separate express lanes from general lanes. These poles are installed to keep drivers in their respective lanes. They are mostly placed on highways with designated entrance and exit points for express lanes. For example, the I-95 express lanes in Miami-Dade and Broward counties have such a system in place.
The plastic poles are not metal or concrete and can be run over, usually without causing major damage to a vehicle. However, they are prone to being damaged and completely broken, which can create gaps that allow drivers to dangerously switch between express lanes and regular lanes. This practice, known as "lane diving", can cause accidents at high speeds. To mitigate this issue, highway planners have installed sturdier poles with narrower gaps to discourage drivers from diving into lanes they are not supposed to be in.
The plastic poles serve as a cheap and effective traffic-calming solution. They help to reduce speeding and excessive speeding over 40 miles per hour has been reduced by up to 40 percent in areas where the poles have been installed. The poles also shorten crossing distances for pedestrians and make it safer for them to cross the road.
While the plastic poles are meant to keep drivers in their designated lanes, some people argue that they are not very effective. Stuart Weissman, a partner at a Miami-based trial firm, commented that the system simply does not work as the poles are often bent, dinged, or missing.

They are also used to shorten crossing distances for pedestrians
Plastic poles, also known as bollards, are being used in cities like Milwaukee to improve road safety. These plastic poles are placed several feet into roadways to slow down speeders by narrowing traffic lanes. They also offer an additional benefit of shortening crossing distances for pedestrians.
While plastic poles are not as sturdy as concrete curbs, they are a much cheaper alternative. They are also more effective than street paint, which typically lasts only three to five years. In addition to being a cost-effective solution, plastic poles have proven to be effective in reducing speeding and encouraging drivers to yield to pedestrians.
In Milwaukee, for example, the installation of plastic poles at around 80 intersections has resulted in a 40% reduction in excessive speeding over 40 miles per hour. The presence of these plastic poles has also increased the number of drivers yielding to pedestrians at crosswalks by six times.
Plastic poles are also used in Florida to separate the I-95 express lanes from the general lanes. These poles are designed to be run over without causing major damage to vehicles. However, they are prone to being damaged and completely broken, creating gaps that allow drivers to dangerously switch lanes.
To address this issue, the Florida Department of Transportation installed sturdier poles with narrower gaps in 2016. These poles aim to discourage drivers from diving into lanes they are not supposed to be in. While some observers consider narrower gaps safer, others argue that they affect visibility on the highway.
