The Federal Motor Carrier Safety Administration has removed 133 electronic logging devices from its registry, citing widespread compliance failures and evidence that some systems were being used to falsify truck drivers’ hours-of-service records.
The enforcement action, announced Thursday by Transportation Secretary Sean Duffy, targeted devices that federal investigators said allowed trucking companies to manipulate driving records, conceal violations of federally mandated rest periods and evade safety regulations.
Of the 133 devices removed, 121 were revoked by FMCSA, while another 12 were voluntarily withdrawn by their providers after failing to meet the administration’s readiness standards.
The crackdown comes as federal regulators intensify scrutiny of trucking safety, driver qualifications and electronic logging systems amid concerns that fraudulent records allow carriers to operate outside federal safety requirements.
As FreightWaves reported in May, FMCSA had removed 79 electronic logging devices from its registered list since January 2025, including 12 devices revoked in a single May enforcement action.
At the time, the agency’s registered ELD list contained approximately 1,050 devices, while its revoked list exceeded 250.
FMCSA did not identify the carriers involved in its most recent investigation, or disclose how many drivers used the affected systems or provided any details connecting individual devices to specific crashes.
FMCSA outlined three examples of alleged ELD fraud discovered during the investigations.
In one case, investigators said they found that an ELD provider allowed motor carriers to call a customer support line and manually erase recorded driving time, replacing it with fabricated rest periods even while drivers remained behind the wheel.
Another provider allegedly uploaded falsified driving logs during an active roadside inspection, concealing evidence that a driver had exceeded federally permitted operating hours.
A third company’s logging records showed trucks traveling at mathematically impossible speeds of up to 130 mph, which investigators said was used to compress recorded driving time, according to FMCSA.
Federal hours-of-service regulations generally limit property-carrying commercial drivers to 11 hours of driving after 10 consecutive hours off duty, with additional restrictions on driving windows and weekly operating hours.
ELDs are designed to automatically record driving time and other vehicle operating information, making it more difficult to falsify records than traditional paper logbooks.
FMCSA said motor carriers using the affected devices have up to 60 days to replace them with compliant ELDs from the agency’s registered devices list.
FMCSA said devices may be returned to the registered list if providers correct all identified deficiencies.
The agency has not disclosed how many motor carriers or commercial drivers will be affected by the removal of the 133 devices.
Why it matters: Trucking companies using the affected devices face replacement costs and potential out-of-service violations as federal regulators intensify scrutiny of electronic driver logs.
