Hours of service Wikipedia. This article is about laws governing commercial drivers in the United States. For laws governing commercial drivers in the European Union, see Drivers working hours. Hours of Service HOS regulations are issued by the Federal Motor Carrier Safety Administration FMCSA and govern the working hours of anyone operating a commercial motor vehicle CMV in the United States. These regulations apply to truck drivers, commercial and city bus drivers, and school bus drivers who operate CMVs. These rules limit the number of daily and weekly hours spent driving and working, and regulate the minimum amount of time drivers must spend resting between driving shifts. For intrastate commerce, the respective states regulations apply. Jd Setup Jd Setup Yahoo more. The FMCSA is a division of the United States Department of Transportation DOT, which is generally responsible for enforcement of FMCSA regulations. The driver of a CMV is required to keep a record of working hours using a log book, outlining the total number of hours spent driving and resting, as well as the time at which the change of duty status occurred. In lieu of a log book, a motor carrier may keep track of a drivers hours using Electronic Logging Devices ELDs, which automatically record the amount of time spent driving the vehicle.

Truck Drivers Hours of Service Truck drivers are regulated by law to drive, work, sleep, and stay offwork. The terms driving, on duty, off duty, sleeping are used. The HOSs main purpose is to prevent accidents caused by driver fatigue. This is accomplished by limiting the number of driving hours per day, and the number of driving and working hours per week. Fatigue is also prevented by keeping drivers on a 2. Rules will be changed so lorry, bus and coach drivers who drive tired will be fined for every time theyve done it in the last 28 days.

Drivers are required to take a daily minimum period of rest, and are allowed longer weekend rest periods to combat cumulative fatigue effects that accrue on a weekly basis. Enforcement of the HOS is generally handled by DOT officers of each state, and are sometimes checked when CMVs pass through weigh stations. Drivers found to be in violation of the HOS can be forced to stop driving for a certain period of time, which may negatively affect the motor carriers safety rating. Requests to change the HOS are a source of contentious debate, and many surveys indicate some drivers get away with routinely violating the HOS. These facts have started another debate on whether motor carriers should be required to use ELDs in their vehicles, instead of relying on paper based log books. PurposeeditDrivers subject to the HOS include any driver of a vehicle which has a gross vehicle weight of 1. The purpose of the HOS is to reduce accidents caused by driver fatigue. As the graph to the right illustrates, the number of hours spent driving has a strong correlation to the number of fatigue related accidents. According to numerous studies, the risk of fatigue is also greatest between the hours of midnight and six in the morning, and increases with the total length of the drivers trip. The FMCSA identifies three main factors in driver fatigue Circadian rhythm effects, sleep deprivation and cumulative fatigue effects, and industrial or time on task fatigue. Circadian rhythm effects describe the tendency for humans to experience a normal cycle in attentiveness and sleepiness through the 2. Those with a conventional sleep pattern sleeping for seven or eight hours at night experience periods of maximum fatigue in the early hours of the morning and a lesser period in the early afternoon. During the low points of this cycle, one experiences reduced attentiveness. Commercial Drivers License CDL General Medical Requirements and Qualifications. During the high points, it is difficult to sleep soundly. The cycle is anchored in part by ambient lighting darkness causes a persons body to release the hormone melatonin, which induces sleep,3 and by a persons imposed pattern of regular sleeping and waking times. The influence of the day night cycle is never fully displaced standard artificial lighting is not strong enough to inhibit the release of melatonin,4 and the performance of night shift workers usually suffers. Circadian rhythms are persistent, and can only be shifted by one to two hours forward or backward per day. Changing the starting time of a work shift by more than these amounts will reduce attentiveness, which is common after the first night shift following a weekend break during which conventional sleep times were followed. Sleep deprivation and cumulative fatigue effects describe how individuals who fail to have an adequate period of sleep 78 hours in 2. A sleep deficit accumulates with successive sleep deprived days, and additional fatigue may be caused by breaking daily sleep into two shorter periods in place of a single unbroken period of sleep. A sleep deficit is not instantly reduced by one nights sleep it may take two or three conventional sleep cycles for an individual to return to unimpaired performance. Industrial or time on task fatigue describes fatigue that is accumulated during the working period, and affects performance at different times during the shift. Performance declines the longer a person is engaged in a task, gradually during the first few hours and more steeply toward the end of a long period at work. Reduced performance has also been observed in the first hour of work as an individual adjusts to the working environment. Definition of termseditParts of a drivers work day are defined in four terms On duty time, off duty time, driving time, and sleeper berth time. FMCSA regulation 3. On duty time is all time from when a driver begins to work or is required to be in readiness to work until the driver is relieved from work and all responsibility for performing work. On duty time includes All time at a plant, terminal, facility, or other property of a motor carrier or shipper, or on any public property, waiting to be dispatched, unless the driver has been relieved from duty by the motor carrier. All time inspecting, servicing, or conditioning any CMV at any time. Crossing a border. All driving time as defined in the term driving time. All time, other than driving time, in or upon any CMV except time spent resting in a sleeper berth. All time loading or unloading a CMV, supervising, or assisting in the loading or unloading, attending a CMV being loaded or unloaded, remaining in readiness to operate the CMV, or in giving or receiving receipts for shipments loaded or unloaded. All time repairing, obtaining assistance, or remaining in attendance upon a disabled CMV. All time spent providing a breath sample or urine specimen, including travel time to and from the collection site, to comply with the random, reasonable suspicion, post accident, or follow up drug testing. Performing any other work in the capacity, employ, or service of a motor carrier. Performing any compensated work for a person who is not a motor carrier. This rule does not explicitly forbid a driver from obtaining a second or part time job. It simply prevents a driver switching from a non driving job to a driving job without the required 1. Driving time is all time spent at the driving controls of a CMV. The sleeper berth is the area toward the rear of the truck cab with the dark tinted windows. Sleeper berth time is any amount of time spent inside the sleeper berth e. FMCSA regulation 3. The simple definition is an area separate from usually immediately behind the driving controls that includes a bed. The rules do not explicitly require that a driver must sleep, only that a driver must take a period of rest within the sleeper berth or off duty i. A statement made by the ICC in 1.
