All bollards have limitations. Most are designed to stop a 12,000-pound vehicle traveling at 10-mph. Most non-commercial vehicles will weigh far less than 12,000 pounds; however, 18-wheelers will weigh far more than 12,000-pounds. These are the bollards that are the ones that are 4″ steel pipes filled with concrete and buried at least 3′ into the ground. But this is what happens when we use these lesser designed bollards around 18-wheelers…
When bollards fail!
