Right but once you've decided to intervene to stop the driver from damaging the bridge, the mechanism of stoppage is your responsibility. The way you stop them may not be, and doesn't have to be, safer than what would happen without intervention. But at the same time you can't go "eh it's cheaper just to kill them."
- ndsipa_pomu 3y agoHitting the height barrier is likely to be less harmful to the driver and other people than hitting the bridge itself, so that seems to be taking due care (and again, killing the driver is extremely unlikely in either scenario). The purpose of a height barrier is to act as a sacrificial component and I would consider that it improves the safety of the structure as well as being cheaper. It's a very common design to see metal or concrete poles (bollards) used to prevent drivers from causing harm to other road users, features or shop fronts. They're safe and effective.
