These surface mounted road blockers have been tested using trucks of various weights and speeds with positive results, although evidence shows that truly surface mounted products are less likely to get a “zero penetration” result.

Portable road blockers have been tested slightly less vigorously.

Road blockers are flexible in terms of foundation depths needed and so can be installed in most terrains, so long as the site circumstances allow for foundations to be properly installed. They offer a visible deterrent, so suit applications where site operators wish to convey a message that the site is accessible to authorised vehicles only and not necessarily to the general public. They can be continuously operated with a high level of duty cycling available and are generally used for government, military, industrial and commercial situations where a higher level of security is required. Road blockers are not normally selected for aesthetics but rather to support a strong message of ‘keep out’ to potential unwanted visitors.

Blockers can be integrated well with other protective security products subject to the control logic utilised. They lend themselves well to being incorporated into interlocking systems (they can be designed to operate in conjunction with each other where their functions are mutually dependent).
