MTOD 988.101 Telespar
- In MTOD Note 2 it states that the sign boards shall not exceed 1.44m squared. Based on the manufacturers crash testing noted in FHWA ss185, the system was tested with a sign board that was 0.3m (12 inches) x 0.45m (18 inches) which would equal 0.35 meters squared. Was there additional testing with a larger sign board that reflects the average or common provincial regulatory signs on Ontario highways similar to a regulatory speed sign at 0.6m (24 inches) x 0.75m (30 inches)? Would like to know if there is Roof Crush or Windshield Deformation data that would support a sign board of that size under MASH full scale crash testing.
