Although trailer mounted portable traffic signals are exempt from crash testing, the FHWA has determined that temporary traffic signals mounted on pedestals must be crash tested:
“Temporary traffic signals mounted on bases or pedestals are considered Category II work zone devices as they are similar in overall configuration to portable sign stands that are routinely crash tested.”
The SQ2 has been successfully tested to NCHRP-350 Test Level 3 crash testing requirements by an accredited independent test facility. The successful test report shall has been accepted by the FHWA with supporting documentation available upon request.
