The Complete Guide to Electronic Logging Devices (ELDs)

For truckers, it is all about staying compliant and conforming to the recurring mandates released by the FMCSA. However, despite the willingness to adhere to most directives, the one concerning ELDs has been a tough nut to crack for most, courtesy of the monitoring rigidities and higher implementation costs.

Regardless of the apprehensions, the ELD mandate, launched way back in 2019 is here to stay and it would be better for fleet managers and independent truckers to adapt to this new-fangled development at the earliest. 

Also, an electronic logging device, strictly from a technical perspective, is feature-laden and capable of generating a safer working environment for commercial truckers. Therefore, despite the hesitations regarding setting one up, it is recommended to learn more about ELDS, the mandate, and how beneficial they can be in minimizing drive fatigue and the number of road accidents.

What are Electronic Logging Devices?

Simply put, an ELD is a standard device with the capability of recording the driving time for compatible commercial vehicles. As far as the functioning is concerned, the piece of hardware readily plugs into the OBD port of the vehicle whilst continually capturing data relevant to location, miles driven, speed, engine status, and more.

Why ELD is such an impactful resource to have?

Believe it or not, an Electronic Logging Device can actually make driving safer. Plus, commercial fleet managers can keep a close eye on the trucker’s whereabouts if an ELD is connected to the concerned dashboard. 

But then, ELD as a concept or rather an enforceable mandate was primarily introduced to recording the HOS i.e. the Hours of Service offered by commercial drivers, across days, weeks, or any stipulated timeframe. With an ELD connected to the commercial vehicle, it becomes easier for the fleet managers to determine the number of service hours put in by the driver, which eventually decides the remuneration, perks, and incentives.

But there is a catch that ELDs can help bypass and get rid of!

Did you know that commercial drivers are only allowed to drive for 11 hours in a 14-hour stretch? As this restriction was brought upon by the federal authorities, it even advocated a bigger role for ELDs, courtesy of their ability to monitor the HOS and record insights in the ELD logbook to help drivers and managers with compliance.

However, an ELD is a lot more than what meets the eye. Although its primary task is to keep a tab on the regulated HOS as a part of the fleet management setup, it can readily capture other data sets by being a part of a vehicle’s telematics setup— with a focus on long-distance signal transmission and continued data projections.

How does a Comprehensive ELD Look Like?

ELDs come in different form factors and can have dedicated GPS tracking setups, accelerometers, and gyroscopes, integrated within. An electronic logging device with the mentioned enhancements is capable of monitoring vehicle data comprehensively, with a focus on the following insights:

  • Engineer speed
  • Commercial load
  • Real-time location
  • Duty status
  • Driving time
  • Idling time
  • Fuel efficiency
  • Mileage
  • Fault code
  • System diagnostics
  • Harsh braking, if any
  • Collisions and other safety-related concerns

With a fully functional ELD capable of monitoring such a diverse range of vehicle-specific functionalities, it would be erroneous to only consider it as a compliance-driving resource. 

What Is The Cost Of ELD?

Controversies were going around the electronic logging device mandate in the early phase. The main issue of every truck driver and business owner was the cost they will have to incur from their traditional logging system to this new solution. 

But the ELD is not expensive- as they were expected. According to the FMCSA, the average price of an ELD is about $495 per truck annually. It is not a fixed amount and can vary from $150 to $800 per truck. It depends on the solution you choose. 

Also, if you want an average of how much you will have to spend, here is an example.

Suppose you want 20 trucks and need an ELD for each one. Say one ELD solution costs $30 per month. You will be paying $600 per month & $7,200 annually. 

You can get an even better deal by subscribing to a long-term plan. For example, many vendors offer a $20-$30 difference in monthly and annual subscription plans

Things To Consider While Choosing An ELD Solution 


You can find many ELD vendors offering free devices with subscription charges. Additionally, there are also companies offering ELD with no subscription fees. 

The main difference between both is that in the first, you will have to incur minimal initial investment and can distribute the cost over time. And in the other one, you will have to pay a heavy amount initially and then sit back and relax enjoying the services. 

Remember even with devices with no monthly subscription fees, after a while, you will have to pay a few dollars to continue using the device. So check out every related clause before deciding on the perfect solution.

Vehicle-installed ELDs V/s BYOD 

There are two options available in the market- vehicle-installed ELDs and bring your device (BYOD). 

  • Vehicle-installed ELDs 

Vehicle-installed ELDs are installed in the cabs of the trucks. These devices display data, including HoS, work logs, sleep hours, working hours, remaining hours, etc. It keeps drivers hands-free and also helps in easy roadside inspections. 

Another advantage of this device is you won’t have to buy any GPS tracker as it comes with built-in GPS tracking capabilities. 

  • Bring Your Device

BYOD allows drivers to carry their devices to comply with the HoS rules. They can download the mobile application and log their working hours with it. 

But do not think BYOD is cheaper as you can use your device. There are several drawbacks, for example, the risk of fines for using mobile phones while driving, lost or damaged devices, forgetting the device at home, battery limitations, etc. So before choosing any, make sure to consider both pros and cons. 


You should also consider the installation process of the ELD. Devices with complex installation will require professional assistance. Even if you decide to do it yourself, you will have to waste your time and effort dealing with wires and difficult processes. 

It can increase the cost, so you might want to get a solution with a simple installation. 


You should go with a simple-to-use device. It will allow you to avoid the extra cost of organizing training programs to help your drivers avoid the new technology. 

Subscription Plans

You should also pay attention to the subscription charges of a solution. 

Remember not to get swayed by the one with low charges. You should also check the features that come with it, for example, IFTA tax reporting, eDVIR, GPS tracker, vehicle diagnostics, compliance monitoring, etc. 

Contacts Or Hidden Fees

Also, stay away from solutions with lengthy contracts or hidden fees. You should choose a device with flexible plans. You should be careful of the solution that charges activation or deactivation fees and hinders your free will to enter and exit. 

How to make the most of an ELD?

Almost every commercial carrier or fleet manager uses an ELD to specifically record the driving time and feed in the HOS in the ELD logbook. However, it is in everybody’s best interest to explore the distinct capabilities of an electronic logging device that extend beyond fulfilling or helping driving comply with the FMCSA mandate.

Needless to say, a beefed-up ELD is certainly a vital cog in the fleet management wheel and its efficient implementation is instrumental when fleet efficiency, sustainability, and safety are concerned.

Managed Compliance

Probably the most important role of any electronic logging vehicle is to manage compliance. When connected to the dashboard, the ELD records duty status and HOS, whilst logging the insights in the ELD logbook or the e-log. As the ELD mandate requires commercial vehicles to have this feature, the inclusion of an electronic logging device simply for the sake of compliance, isn’t such a bad option.

Efficient Routing 

Should you end up investing in a holistic ELD, it is better to explore the same, in regard to improved routing. ELDs that come integrated with GPS monitoring hardware can track the vehicle route in real-time, thereby allowing fleet managers to keep a close eye on the drivers.

Vehicle Maintenance, Simplified

As the ELD is plugged into the OBD port of the concerned vehicle, it can readily pull out fault codes, average mileage, and other critical data sets pertaining to the engine. The insights can be extrapolated to arrange for preventative vehicle maintenance. Plus, an all-inclusive ELD comes with a dedicated application, which allows drivers to fill in the DVIRs as they travel, thereby minimizing the back-office workload and downtime issues.

Improved Safety

Certain ELDs come equipped with integrated accelerometers and gyroscopes, which are capable of identifying harsh turns, sudden braking, collisions, and other untoward movements. The data, if and when logged, is immediately transmitted to the fleet manager, which can be used to handle DOT compliance and improve driving training methods.

Loss Prevention

Avant-garde ELDs come with specialized abilities and features, including Geofencing support. This attribute allows truckers to generate a virtual frontier, simply for the sake of security and loss prevention. Once the Geofence is set up, it becomes easier to proactively detect problems related to theft. 

All-Inclusive Reporting

With an ELD by your side, pursuing robust reporting is hardly an issue. As a fleet manager, you can continuously procure insights related to harsh events, idling time, fuel usage, risky driving, and more, which can then be deployed to specifically identify an area that needs improvement.

How to deploy an ELD for procuring actionable data and establishing compliance?

Using an electronic logging device doesn’t require a lot of technical prowess. While the vehicle needs to have an OBD port for seamless installation, once onboard, the ELD can start pulling data directly from the vehicle’s engine. ELD ensures that feeds are generated even when the engine is turned off and with GPS navigation; it becomes possible to transmit the data to the concerned authorities. 

As a fleet manager, if you have the best ELD installed on the vehicles, it becomes possible to procure real-time information, pertaining to the vehicle condition and routers. Plus, certain ELDs keep transmitting data whilst feeding off the vehicle’s battery, either to keep back-office records or to provide details to the DOT inspector, in case of a casual roadside check-up. 

ELD Transmission- What and How?

ELDs can work across a wide range of technologies, especially when it comes to transmitting actionable data. While a cellular transmission is the most common form of conveying information, some devices also rely on Bluetooth connectivity to send data across to the mobile application of the driver.

However, a few top-shelf ELDs also boats integrated Wi-Fi hotspots, which in turn establish a dedicated connection between the mobile app and the ELD device. This functionality also allows truckers to accept work orders and identify route changes, even in real time. 

Can ELDs directly transfer data to the Department of Transportation?

Yes, ELDs can assist drivers whenever a road inspection is around the corner. As the DOT mandates truckers to abide by the HOS regulations, they can always ask the driver to pull the details for cross-referencing. Therefore, it is advisable to invest in an ELD that is capable of supporting the localized transfer of data, either via wireless web or emails. 

The FMCSA, however, finds the Wireless Web service as a more credible method of data transfer. 

Is it mandatory for every driver to get an ELD?

Firstly, every long-haul commercial vehicle needs to have an ELD connected to the dashboard. While this seems like a norm, we should consider it with a grain of salt, as the initial cost of setting it up, uniformly across the fleet, can be a time and cost-intensive job.

Also, as per the ELD mandate, something that we would be discussing in our next discussion, an electronic logging device is of paramount importance to commercial independent drivers or even truckers who are on a company’s payroll. But then, one aspect of the ELD mandate i.e. the one where RODs or ‘Record of Duty Status’ need to be provided, can be exempted from the set of directives, for short-haul companies.

However, if you require a more simplistic explanation of the imminence of ELDs, you must take note of the following factors:

  • ELD is mandatory for long-haul drivers who also need to maintain and provide RODs
  • ELDs and RODs can be done away with under the short-haul commercial exemption plan
  • Tow away drivers, older vehicles without dedicated OBD ports, and contractual drivers need not require an ELD but the ROD maintenance is still mandatory for them

Are ELDs worth it?

While certain drivers feel that having an ELD integrated with the dashboard makes them less flexible in terms of working hours, the benefits clearly outweigh the problems surrounding the implementation of the same. Although the hardware, installation, training, and subscription fee can look gargantuan at the start, ELDs can significantly minimize fuel wastage, lower commercial insurance premiums, assist with vehicle diagnostics, improve road safety, and improve route management. 

Overall, ELD installation is a win-win for the company, administration, and even the drivers, albeit in the mid to long term.
