30-minute Break Rule

The Federal Motor Carrier Safety Administration’s (FMCSA’s) 30-minute break rule for commercial motor vehicles (CMV) drivers came into effect July 1, 2013. The 30-minute break rule essentially says that if a driver has been driving continuously for 8 hours, he needs to have a break of 30 minutes. It is important to know that drivers can work more than 8 hours without taking the 30-minute break if they are not driving. This means that they can perform on-duty tasks or other non-driving functions for more than 8 hours since their last off-duty break. This can include refueling, loading, unloading, logging and other tasks. However, the drivers should not go over their total on-duty hours for the day.

An important point to note about the 30-minute break rule is that the break period must be consecutive, all at once, to count. For example, a driver cannot take a 10 minutes break, and then a 20 minute break later and have either of those count as their 30-minute break.

If during your 30-minute break, you are asked to move your vehicle, and you are logging your break time using an electronic logging device (ELD) such as DriveELD, your log will automatically change your duty status to On Duty Driving which will break your 30-minute Off Duty break. In DriveELD, if your carrier has allowed it, there is an Off Duty Personal Conveyance duty status which would allow you to move your truck without ending your break.

Drivers exempt from the 30-minute break rule

  • Short-haul drivers who stay within a 100 air-mile radius of their starting location.
  • Non-CDL drivers who stay within a 150 air-mile radius of their starting location

Understanding the 30 Minute Break Rule for Truck Drivers

The 30 Minute Break Rule for truck drivers is a critical regulation that aims to enhance road safety by ensuring drivers have adequate rest during long hauls. This rule is part of the Hours of Service (HOS) regulations set by the Federal Motor Carrier Safety Administration (FMCSA) and plays a vital role in reducing fatigue-related incidents on the road.

30 Minute Break Law

The 30 Minute Break Law mandates that commercial truck drivers must take a 30-minute break after driving for 8 cumulative hours without at least a 30-minute interruption. This rule is applicable to drivers carrying property and is designed to prevent the risks associated with long periods of uninterrupted driving.

Key Aspects of the Rule

  1. Timing of the Break: The break can be taken at any time within the 8-hour window but must last at least 30 minutes. This time is meant for drivers to rest and must be off-duty or in the sleeper berth.
  2. Flexibility: The rule offers some flexibility. Drivers can take the 30-minute break whenever they feel the need within the 8-hour driving window.
  3. Exemptions and Modifications: Certain situations, like adverse driving conditions, may allow for modifications to this rule. Also, short-haul drivers are exempt from the 30-minute break requirement.
  4. Enforcement and Compliance: Compliance with the 30 Minute Break Rule is monitored through Electronic Logging Devices (ELDs) which track driving hours. Failure to comply can result in penalties and fines.

Importance of the Rule

  • Enhances Road Safety: By mandating breaks, the rule helps reduce fatigue among truck drivers, which is a major factor in road accidents.
  • Improves Driver Health: Regular breaks help reduce the health risks associated with long hours of sitting and driving, such as heart disease and obesity.
  • Increases Alertness: Rest breaks help maintain a driver’s alertness and concentration, crucial for safe driving.


The 30 Minute Break Rule for truck drivers is a significant step towards ensuring the safety of both the drivers and other road users. By mandating regular rest periods, it not only helps in reducing fatigue-related accidents but also promotes better health and alertness among truck drivers. Compliance with this rule is not just a regulatory requirement but a critical aspect of road safety.
