Understanding HOS Rules for Small Trucking Operations

Why HOS Rules Exist

Hours of Service (HOS) regulations exist for one reason: to prevent fatigue-related crashes. Tired drivers are dangerous drivers. The FMCSA estimates that driver fatigue is a factor in approximately 13% of commercial vehicle crashes. HOS rules set limits on how long a driver can operate a commercial motor vehicle before they must take a break.

For small trucking operations, HOS compliance can feel overwhelming. The rules are detailed, the penalties are steep, and the ELD mandate means everything is tracked electronically. But the fundamentals are straightforward once you understand the key limits and how they interact.

The Core HOS Rules for Property-Carrying Drivers

Most small trucking operations haul property (freight), not passengers. Here are the four core rules that govern property-carrying CMV drivers:

11-Hour Driving Limit

A driver may drive a maximum of 11 hours after 10 consecutive hours off duty. This is the fundamental limit. When you hit 11 hours of driving time, you must stop driving — no exceptions, no extensions (outside of the adverse driving conditions exception).

14-Hour Driving Window

A driver may not drive beyond the 14th consecutive hour after coming on duty, following 10 consecutive hours off duty. This is the "window" — once it opens, it closes 14 hours later regardless of how much driving you have actually done. Breaks, loading time, and other on-duty activities all count against this window.

This is the rule that trips up most drivers. You can have only 8 hours of driving in your log, but if your 14-hour window has expired, you cannot drive. Time spent waiting at a shipper's dock, fueling, or doing paperwork all eat into your available window.

30-Minute Break Requirement

A driver must take a 30-minute break after 8 cumulative hours of driving time. The break can be taken as off-duty time or as on-duty not driving time (such as fueling or doing a post-trip inspection). The 30 minutes must be consecutive — you cannot split it into two 15-minute breaks.

60/70-Hour Limit

A driver may not drive after 60 hours on duty in 7 consecutive days, or 70 hours on duty in 8 consecutive days. Most carriers use the 70-hour/8-day rule because it provides more flexibility. This limit can be reset with a 34-hour restart that includes two periods between 1 a.m. and 5 a.m.

The Short-Haul Exemption

Many small trucking operations qualify for the short-haul exemption, which provides significant relief from ELD and HOS documentation requirements. To qualify, a driver must:

Operate within a 150 air-mile radius of their reporting location
Start and end their duty day at the same location
Complete their duty day within 14 hours
Not exceed 11 hours of driving time

Drivers qualifying for the short-haul exemption are not required to use an ELD or maintain a detailed Record of Duty Status (RODS). They must maintain accurate time records showing the time they report for duty and are released from duty each day.

This exemption is a game-changer for local delivery fleets, construction haulers, and other operations that operate close to home base. However, the moment a driver exceeds the 150 air-mile radius or any other qualifying condition, they must switch to full ELD compliance for that day.

Common HOS Violations and Penalties

HOS violations are among the most common findings during roadside inspections and compliance audits. The most frequent violations include:

Driving beyond the 11-hour limit: Fines of $1,000-$16,000 per violation
Driving beyond the 14-hour window: Same penalty range
Falsifying ELD records: This is treated as a serious offense and can result in driver disqualification
Missing or incomplete records: Fines of $1,000-$16,000
Failure to have a functioning ELD: Driver placed out of service

Beyond fines, HOS violations affect your carrier's Safety Measurement System (SMS) score, which can trigger a FMCSA compliance review or audit. Repeated violations can put your operating authority at risk.

Practical Tips for Small Fleet Compliance

Train your drivers: Most HOS violations stem from misunderstanding the rules, not intentional noncompliance. Invest in regular training.
Plan routes with HOS in mind: Build loading, unloading, and break times into your trip planning. A tight schedule that forces drivers to push limits is a compliance and safety failure.
Monitor ELD data daily: Do not wait for a roadside inspection to discover a problem. Review driver logs daily and address issues immediately.
Know your exemptions: If your drivers qualify for the short-haul exemption, use it. It significantly reduces your compliance burden.
Document everything: When in doubt, document it. Adverse driving conditions, personal conveyance, yard moves — all have specific documentation requirements.

How NovaGear Helps

NovaGear's DOT compliance module tracks driver hours, monitors HOS limits, and alerts you to potential violations before they happen. Drivers can log duty status changes from their phone, and fleet managers can view real-time compliance dashboards that show every driver's available hours at a glance.

For operations using the short-haul exemption, NovaGear automatically tracks the 150-mile radius and duty day length, alerting drivers and managers if they are approaching the exemption boundaries. This prevents accidental loss of short-haul status that can create immediate ELD compliance requirements.
