DOS K12 Crash Rating For Heald

This is the only Roadblocker of its kind that has passed both PAS 68 and the Department of State K12 certification.

The unique design of the Roadblocker is the key to its success. Special crash bars and a sacrificial front radius are incorporated into the design so upon impact these absorb the force and leave the main body of the blocker unharmed, ready to continue maintaining site security. Even after removal of the radius plate the Road blocker is still fully operational and in the upright position remains a formidable barrier against potential unauthorised entry.
The front radius can be quickly and easily replaced without compromising site security in approximately one hour.

Department of State (DOS) Crash Test Certification

Prior to Department of State (DOS) certification, vehicle barriers must be tested by an independent crash test facility to meet DOS standards.

- Speed (K)
- Penetration

The test specifies perpendicular barrier impact by a 15,000 lb. (6810 kg.) vehicle.


Certification - Class Speed in mph - Speed in kph
K12 - 50 mph - 80 kph
K 8 - 40 mph - 65 kph
K 4 - 30 mph - 48 kph


To become certified with a Department of State "K" rating the 15,000 vehicle must achieve one of the K rating speeds (50 mph, 40 mph, or 30 mph) and the bed of the truck must not penetrate the barrier by more than 36 inches.
