Registered Today Is Not Registered Forever
What the Registration Covers
Registration means the manufacturer self-certified that Guardrail meets the ELD technical specification — automatic driving-time capture, tamper resistance, a standard data file, and a supported roadside transfer method. It does not mean FMCSA independently tested the device, which is exactly why the agency also maintains a revoked list and why you should verify before you buy.
