Transpo's Break-Safe® Omni-Directional Breakaway System is for ground mounted signs located within roadside clear zones and other locations vulnerable to vehicular impacts. The omni-directional performance of Break-Safe® allows the system to break away with consistent, predictable behavior, regardless of the vehicle's angle of impact, thus saving lives and reducing property damage.
Break-Safe® is designed to support a wide range of post sizes, up to and including the largest permitted by AASHTO. The flexibility built into the system gives you many choices when selecting post types and sizes for specific applications. Use our unique Sign Post Selection Program to select the proper sign posts in accordance with AASHTO LTS-6 (2013).
The high-strength coupling and L-bracket design provides increasing structural capacity as the size of the post increases. This unique feature offers unmatched load-carrying capacity, and accommodates both single and multiple post configurations.
Break-Safe® offers the lowest stub height after impact (less than one inch) of any current sign breakaways. This is essential for maximum safety and allows for variations in foundation height.
Features and Advantages
- supports a wide range of post sizes
- high-strength coupling and L-bracket design
- lowest stub height after impact
- rapid re-installation
- no special tools or equipment required
- high structural load-carrying capacity
- superior safety performance
Accident research and field experience have shown that vehicles often leave the roadway impacting structures at high angles of incident. Break-Safe® has been crash-tested, resulting in a FHWA acceptance letter based on NCHRP Report 350 and also accepted under MASH 08. New national signing standards specify increased sign sizes for visibility, in addition to increased wind load levels. These changes create a significant increase in structural demands on sign supports.
No special tools or equipment are required to install and maintain Break-Safe®. All components are easily secured using the American Institute of Steel Construction (AISC) turn-of-nut tightening method, eliminating the torque requirement typical with other breakaway systems.
