The electronic logging device (ELD) mandate, established under federal regulations as the ELD Final Rule, was introduced to improve commercial motor vehicle safety by keeping accurate records of drivers’ working hours. While federal requirements apply to interstate carriers, individual states have adopted their own electronic logging rules for intrastate operations. Understanding the current ELD mandate in California is essential for motor carriers operating both within the state and across state lines.
What Is the Federal ELD Mandate?
The federal ELD Final Rule was published in December 2015, giving interstate motor carriers two years to comply, until December 18, 2017. This regulation, enforced by the Federal Motor Carrier Safety Administration (FMCSA), generally requires commercial drivers who maintain records of duty status (RODS) to use electronic logging devices. These devices connect to the vehicle’s engine to automatically record vehicle movement, engine status, mileage, and driving time. Electronic logs help drivers, carriers, and enforcement authorities track hours of service (HOS) and check that drivers follow the applicable driving limits. The logging system includes both hardware and software to collect and manage this information.
What Is the California ELD Mandate?
California added federal electronic logging requirements to its state regulations under Title 13 of the California Code of Regulations (CCR), making electronic logging mandatory for intrastate drivers who fall under the rule. The California ELD mandate took effect on January 1, 2024, with no additional grace period. The California Highway Patrol (CHP) is responsible for enforcing these requirements during roadside inspections and other commercial vehicle checks.

Who Must Follow the ELD Mandate in California and Who Is Exempt?
According to FMCSA and CHP guidelines, most commercial drivers who are required to maintain RODS must use a registered electronic logging device.
However, California ELD exemptions allow certain drivers to use paper logs or other permitted records instead of electronic logging systems. These include:
- Short-haul radius exemption. Drivers operating within a set distance from their normal work reporting location (150 air miles for federal interstate operations and 100 air miles for California intrastate operations) may qualify if they return to that location daily and keep time records instead of RODS.
- 8-day paper log threshold. Drivers who need to maintain RODS for no more than 8 days in any rolling 30-day period.
- Driveaway-towaway operations. Drivers transporting a commercial vehicle as the product being delivered, or moving a motorhome or travel trailer with at least one set of wheels on the road under a qualifying operation.
- Pre-2000 engine model years. Under federal rules, drivers of vehicles with engines built before model year 2000 may qualify for an exemption. Eligibility must be supported by the relevant vehicle or engine records.
California follows the same federal technical standards for electronic logging, but intrastate drivers may be subject to different hours of service rules. Understanding California ELD exemptions and HOS rules helps carriers determine which requirements apply to their operations, whether they work within the state or cross state lines.
Federal Interstate vs. California Intrastate HOS Rules
While interstate carriers must follow federal HOS rules, commercial motor carriers operating strictly within state borders generally follow California’s intrastate HOS rules. Understanding these differences helps carriers plan driver schedules and avoid violations:
- 11/12-hour driving limits. Interstate commercial drivers operating under federal rules can drive for up to 11 hours after taking 10 consecutive hours off duty. California intrastate drivers generally can drive for up to 12 hours after the same rest period.
- 14/16-hour workday windows. Federal regulations do not allow driving after the 14th consecutive hour following a qualifying rest period. California intrastate regulations generally allow a 16-hour on-duty window.
- 60/70/80-hour weekly caps. Federal rules prohibit driving after 60 hours on duty in 7 days or 70 hours in 8 days, depending on the carrier’s schedule. California intrastate rules generally allow up to 80 hours on duty over 8 consecutive days. Both sets of rules allow a 34-hour off-duty restart under the applicable conditions.
- Mandatory rest interruptions. Federal interstate property-carrying drivers must take a 30-minute break after 8 cumulative hours of driving without a qualifying interruption. California intrastate rules generally do not require the same federal driving break, but employers must follow applicable state meal and rest break rules.
Both interstate and intrastate carriers operating in California that are affected by the electronic logging requirement must use FMCSA-registered ELDs to keep RODS. Selecting a reliable electronic logbook provider that supports both sets of rules helps carriers track driver hours correctly and avoid logging errors.

Setting Up and Managing ELD Systems
The first step is choosing a compliant device. The FMCSA keeps a list of registered ELDs. Before buying a device, check that the model is on the approved list and check the revocations list periodically.
The electronic logbook display must be mounted securely inside the cab, where the driver can see it from the normal driving position. Drivers should be able to check that the device is working without using it while driving.
After installing the device, the carrier should set up separate user accounts with unique login details. Drivers, supervisors, and support staff should have accounts with access based on their roles. Employees who work as both drivers and managers should use separate profiles for each role.
The logging hardware connects directly to the vehicle’s engine. Before starting a trip, the driver must log in to their account in the electronic logbook app. Once the vehicle starts moving, the system automatically records driving time and updates the driver’s duty status.
Setting Up and Managing Fleet Systems
Setting up an electronic logging system involves a few important steps to keep the devices working properly and driver records secure:
- Registry verification. Before purchasing or installing a logging device, check that the model appears on FMCSA’s official list of registered ELDs.
- In-cab hardware mounting. The mobile display must be mounted securely where the driver can see it from the normal driving position, without causing distractions.
- User account structure. Each driver and staff member should have a separate account with unique login details. Drivers, dispatchers, and safety managers should have access based on their responsibilities. Employees with both driver and manager duties should use separate profiles for each role.
Once the engine gateway connects to the diagnostic port, the driver logs in to the mobile app before moving the vehicle. The system then connects with the engine automatically and records vehicle movement, distance, and driving time.
Executing Roadside Inspection Protocols in California
During a CHP roadside inspection or weigh station check, commercial drivers must provide their electronic records of duty status when requested. A simple inspection process helps drivers present the required records while keeping personal information private.
Activating Screen Inspection Mode
Before handing a mobile phone or tablet to an inspecting officer, the driver can open DOT Inspection Mode in the elog app. This mode shows the required HOS records, including duty status graphs, vehicle information, and logs for the current day and previous seven days. It also helps keep personal information, such as text messages, photos, and other apps, separate from the inspection records.
Secure Web Services eRODS Transfer
When requested by a CHP officer, the mobile application prepares the current day’s log and records for the previous seven consecutive days. The system can send these records through FMCSA-supported web services or email, allowing officers to review the required information electronically.
Knowing how to use inspection mode and transfer logs helps drivers complete inspections more smoothly and avoid unnecessary delays at weigh stations.

Understanding the CARB Clean Truck Check Program
Apart from the use of electronic logbooks, commercial motor carriers operating in California must also meet environmental rules. Under the California Air Resources Board (CARB) Clean Truck Check regulation, affected heavy-duty vehicles with a gross vehicle weight rating (GVWR) over 14,000 pounds must pass regular emissions tests. This includes qualifying trucks registered outside California that operate on the state’s roads.
Mandatory Periodic Testing
Heavy-duty vehicles equipped with On-Board Diagnostics must submit passing emissions test results to CARB at the required intervals. Missing a deadline or failing to resolve a compliance issue can lead to penalties and other enforcement actions. Depending on the situation, carriers may face DMV registration holds, civil fines, or restrictions on operations at California ports and intermodal railyards.
The Operational Advantage of Remote CTC Testing
Traditional emissions compliance often means taking a truck to a testing shop or arranging a mobile inspection. Each visit may cost $150 to $300, and scheduling the test takes time.
HOS247 offers automated CARB testing through continuously-connected telematics hardware. The device connects to the vehicle’s diagnostic port and collects the required OBD data while the truck runs its normal routes. It then sends test data to CARB through the approved system, reducing the need for shop visits and extra work for drivers.
Combining HOS logging and automated emissions testing in the same hardware saves money and simplifies keeping track of compliance.

Frequently Asked Questions About California Trucking Rules
California requires electronic logging devices for most intrastate commercial drivers who must maintain RODS, under Title 13 of the California Code of Regulations. These devices must meet the same FMCSA technical standards as those used for interstate operations. The California Highway Patrol (CHP) checks compliance during roadside inspections.
Yes. HOS247 offers compatible hardware that supports both electronic logging and CARB CTC testing. The device connects to the truck’s diagnostic port to record driving data and collect the engine information needed for emissions testing. This allows carriers to manage driver logs and complete eligible CARB tests without installing separate devices, helping reduce equipment costs and downtime. The device and platform also support GPS fleet tracking and IFTA mileage calculations features.
Yes. Most covered non-gasoline commercial vehicles with a GVWR over 14,000 pounds must meet CARB Clean Truck Check requirements when operating on California public roads, even if they are registered in another state. Some vehicle exemptions apply.
A CARB-certified, connected telematics device stays plugged into the vehicle’s diagnostic port. It collects the required OBD data during normal truck operation, when the truck is idling, and sends the test results to CARB through the Clean Truck Check Vehicle Inspection System (CTC-VIS). This allows compatible trucks to complete testing without separate shop appointments or extra steps for drivers.
Commercial drivers must keep the required electronic logbook documents available in the cab. These include instructions for transferring electronic logs, device malfunction procedures, a user manual, and at least eight days’ worth of blank paper log sheets. FMCSA allows these materials (except for the log sheets) to be stored electronically, provided drivers can access them when needed.
When an electronic logging device malfunctions, the driver must notify the motor carrier within 24 hours and use paper logs when the problem prevents accurate electronic recording. The motor carrier generally has eight days to repair or replace the device.
