How to Defend Against Hours of Service (HOS) and ELD Violations in Montana

Driving a commercial motor vehicle across Montana's vast highways is a demanding job. To ensure safety, both the state and the federal government strictly regulate how many hours you can spend behind the wheel. The introduction of Electronic Logging Devices (ELDs) has made it easier for inspectors to track every minute of your day. If you receive a violation during a weigh station stop or a roadside inspection in places like Billings, Missoula, or Great Falls, your commercial driver's license (CDL) and your livelihood are at risk.

We highly recommend reviewing our directory to find a local Montana traffic defense attorney who specializes in commercial trucking laws. A skilled lawyer can help you challenge the ELD data and protect your driving record from points and license suspensions.

Understanding FMCSA Hours of Service (HOS) Rules

The rules governing your driving time are set by federal law under 49 C.F.R. § 395.3 and adopted by the state under Mont. Code Ann. § 61-10-154. It is critical to understand the four primary time limits that officers look for during a roadside inspection.

The 11-Hour Driving Limit

After taking 10 consecutive hours off duty, a property-carrying commercial driver may drive for a maximum of 11 hours. If your ELD shows you driving for 11 hours and 15 minutes, you will likely be cited. The Montana Highway Patrol Commercial Vehicle Enforcement Bureau, Helena frequently checks logs for drivers pushing past this limit to make tight delivery schedules.

The 14-Hour Duty Limit

Your driving must be completed within a 14-hour window after coming on duty following 10 consecutive hours off duty. Even if you spend 4 hours waiting at a loading dock in Bozeman, that time counts against your 14-hour clock. You cannot drive after the 14th hour unless you take another 10-hour rest period.

The 60/70-Hour Weekly Rules

To prevent exhaustion over a long workweek, the FMCSA prohibits driving after you have been on duty for 60 hours in 7 consecutive days, or 70 hours in 8 consecutive days. You can only restart this 70-hour clock after taking 34 or more consecutive hours off duty, which is commonly referred to as the 34-hour restart.

The 30-Minute Break Requirement

You must take a 30-minute break after driving for 8 cumulative hours without at least a 30-minute interruption. This break can be logged as off-duty, sleeper berth, or even on-duty not driving, as long as you are not physically sitting behind the wheel operating the truck.

Fighting Electronic Logging Device (ELD) Violations

ELDs are essentially computers, and computers make mistakes. If an officer writes you a ticket based on faulty ELD data, you can defend yourself. Common defenses include proving that the device malfunctioned, that the GPS tracking recorded an incorrect duty status due to signal loss in rural Montana, or that your carrier failed to update the software. If you receive an unfair citation, you or your attorney can submit an electronic Request for Data Review (RDR) directly through the FMCSA DataQs portal to try and get the violation removed from your motor carrier's safety record.

The Adverse Driving Conditions Exception (Montana Winters)

Montana is famous for sudden, severe winter storms. Federal regulations recognize that weather can cause unexpected delays. Under the Adverse Driving Conditions exception, you may extend your 11-hour driving limit and your 14-hour driving window by up to 2 hours to find a safe place to park. To successfully use this defense in a Yellowstone County Justice Court, Billings or a Missoula County Justice Court, Missoula, your lawyer must prove that the snowstorm, ice, or traffic accident was completely unpredicted when you started your run. If the weather forecast clearly warned of a massive blizzard on Interstate 90 hours before you departed, the judge will not allow you to use this exception.

Cost of Defense and Process Timeframes

If you are ticketed for an HOS violation, you face state fines that typically range from $100 to $500 depending on the severity of the overage. Hiring a CDL defense attorney in Montana generally involves an initial flat fee between $500 and $1,500 for a straightforward logbook ticket. Fighting the ticket in court usually takes 30 to 90 days. Your attorney will handle discovery requests to obtain dashcam footage and the officer's notes, saving you the time of having to return to the county where you were pulled over.
