How deep should vehicle protection posts be installed into the ground?

1. 5" to 10"

2. 10" to 15"

3. 10' minimum to 20' maximum

4. 15' minimum to 25' maximum

The correct answer is: 10' minimum to 20' maximum

The depth at which vehicle protection posts should be installed into the ground is generally guided by the need for stability and resistance to impact. A minimum depth of 10 feet is significant because it ensures that the posts can withstand the forces exerted by vehicles during collisions or accidents. In contexts such as preventing unauthorized vehicle access to sensitive areas or providing barriers in high-traffic environments, the deeper embedding allows for greater support and durability. The maximum depth of 20 feet is also significant as it reflects the potential need for sturdy, reinforced installations in specific hazardous locations, ensuring that the posts remain firmly rooted. Choosing a depth that balances these factors helps to enhance safety while complying with relevant codes and regulations. The other options do not provide the same level of durability or stability needed for effective vehicle protection, which is critical in fire safety and overall site management.
