Does the registration process require companies to exclusively use FMCSA’s test procedure? Will vendors have access to testing facilities for ELDs?

No. ELD manufacturers may use any test procedure they choose and note this in the registration. FMCSA will not provide a third-party testing service. FMCSA will only investigate devices that are suspected of not conforming to specifications, and will conduct testing with the FMCSA compliance test procedure during its investigation.
