Rationally speaking, it seems a 5-year temporary exemption for Intellistop would be the most ideal way to get results and data on pulsing brake lights and rear-end collisions.
After five years, if the data doesn’t prove that CMV’s safety was equivalent to or greater than before using Intellistop, then they do not have to renew the exemption—this is the reason temporary exemptions should be issued.
While the temporary exemption was denied to Intellistop, the FMCSA said they would give specific consideration to individual fleets seeking their own exemptions for use of the Intellistop module.
Any carrier that wishes to reduce rear-end collisions should request an exemption to use Intellistop.
