ELD Compliance
ELD compliance refers to adherence to the FMCSA's Electronic Logging Device mandate, which requires commercial truck drivers to use certified electronic logging devices to automatically record hours of service (HOS) data instead of paper logs. Under HOS rules, drivers can operate a maximum of 11 hours driving within a 14 hour on duty window after 10 consecutive hours off duty.
Why it matters
ELD compliance directly constrains how many hours a driver can operate before mandatory rest. Shippers who book unrealistic transit times or create excessive detention pressure carrier drivers into HOS violations with serious safety and legal consequences. HOS violations carry fines of up to $16,000 per occurrence, and carriers with poor CSA scores face increased inspection rates that slow their entire fleet.
When to use it
Factor ELD hours-of-service limits into transit time planning for any long-haul move, especially those approaching 11 driving hours or 14 on-duty hours, to set realistic delivery expectations. For lanes over 500 miles, confirm whether the move requires a mandatory 10 hour rest break and plan delivery windows accordingly.
How Warp thinks about it
Warp's drivers operate under full ELD compliance. Transit windows and lane commitments are built around legal HOS limits, ensuring that on-time performance is achievable without pressuring drivers. Our AI backbone, Orbit, builds HOS constraints into every route plan so lane commitments reflect what is legally and safely achievable.
