Hours of Service (HOS)

The Federal Motor Carrier Safety Administration (FMCSA) regulates Hours of Service (HOS) to ensure that commercial drivers operate their vehicles safely and do not exceed their limits. Here’s an overview of the key regulations:

Key Regulations

Maximum Driving Time

Property-Carrying Drivers: A driver may drive a maximum of 11 hours after 10 consecutive hours off duty.

Passenger-Carrying Drivers: A driver may drive a maximum of 10 hours after 8 consecutive hours off duty.

14-Hour Rule

Drivers cannot drive beyond the 14th hour after coming on duty, following 10 consecutive hours off duty. This rule applies regardless of the number of driving hours completed.

Rest Breaks

Drivers must take a 30-minute rest break after 8 cumulative hours of driving time. The break can be taken before or after the 8-hour mark.

Weekly Limits

Drivers cannot exceed 60 hours of driving in 7 consecutive days or 70 hours in 8 consecutive days. This limit resets after the driver takes 34 consecutive hours off duty.

Split-Sleeper Berth Provision

Drivers can split their required 10 hours off duty into two periods, provided one period is at least 2 hours and the other at least 7 hours. This allows for more flexible scheduling.

Record Keeping

Drivers must maintain accurate records of their driving hours, typically using electronic logging devices (ELDs) or paper logs.

Exemptions and Special Considerations

Certain drivers, such as those operating within a 150 air-mile radius and not driving more than 8 hours without a break, may qualify for a short-haul exemption.

Adverse driving conditions can extend driving time by up to 2 hours.

Purpose

The HOS regulations aim to reduce accidents caused by driver fatigue, enhance road safety, and promote the well-being of commercial drivers.
