To establish safety and licensing standards for trucks, buses, and semi-trailers where gross vehicle weight exceeds 10,000 pounds.
The United States Department of Transportation's (DOT) Motor Carrier Safety Regulations cover all interstate and intrastate motor carriers of property or passengers whether common, contract, or private, including drivers, officers, agents, representatives, and employees.
The two broad areas of the safety regulations relevant to agriculture include
Drivers of farm trucks subject to Commercial Driver's License (CDL) requirements and hazardous materials regulations.
Vehicles and drivers transporting migrant farm workers (see EDIS document FE406, Migrant and Seasonal Agricultural Worker Protection Act (MSPA) [Federal]).
Farm Vehicle Waivers
The Motor Carrier Safety Regulations permit states to waive CDL requirements for certain groups. This includes certain farm vehicle operators as long as the vehicle
Is controlled and operated by a farmer.
Is used to transport agricultural products, farm machinery, or farm supplies to and from a farm.
Is not used in the operation of a common or contract motor carrier.
Is operated within 150 miles of the person's farm.
To receive this exemption, drivers must complete Form CDL-2(4190).
This is not a blanket waiver for all drivers of all farm-related vehicles. At its broadest interpretation, it applies only to the farmer-operator of vehicles hauling nonhazardous materials that do not travel more than 150 miles from the farm.
CDL waivers do not apply to drivers of vehicles designed to transport passengers, including migrant or seasonal agricultural workers.
For these reasons, it is important for farm employers to understand and comply with DOT regulations governing road testing, medical examinations, drug and alcohol testing, equipment, maintenance, and transportation of hazardous materials.
Physical Requirements of Drivers
Drivers of farm vehicles must meet the physical requirements and comply with all other provisions of the Federal Motor Carrier Safety Regulations. Conditions where a person cannot drive a farm vehicle include
Loss of a foot, leg, hand, or arm unless the person has been granted a waiver.
Any impairment of a hand or fingers which interferes with prehension (the act of taking hold or grasping).
Any impairment of an arm, foot, or leg which interferes with the ability to perform normal driving tasks.
Diabetes, cardiovascular disease, respiratory dysfunction, high blood pressure, arthritis, or epilepsy likely to interfere with safe driving.
Addiction to habit-forming drugs or alcohol.
Color blindness or uncorrectable visual acuity.
Diminished hearing greater than 10/20.
Driver's Qualification File
Each driver must have a qualification file which may be kept with the driver's personnel file. Operators are required to keep the files at their principal place of business and retain them for three years after termination of the employee.
If you meet the definition of a farm vehicle operator, you are exempt from the driver's qualification file portion of the regulation.
Each person must be tested to demonstrate that he or she is capable of operating the type of motor vehicle he or she intends to drive.
A driver may present a valid operator's license issued by the state driver's license testing bureau as an alternative to the road test. If he or she does, the employer must photocopy the license and keep it with the driver's qualification file. If the employer chooses to use the road test, it must be given by a person who is competent to evaluate whether the individual taking the test has demonstrated he or she is capable of operating the equipment.
If you meet the definition of a farm vehicle operator, you are exempt from this section of the regulation.
The medical examination must be given by a licensed doctor every two years and must be included in the driver's qualification file. The driver of a motor vehicle must have in his/her possession a medical examiner certificate card or a photocopy of the medical examination.
All farm vehicle operators are exempt from the requirements for medical examinations. If you drive a combination vehicle, such as a tractor-trailer, you need to have a medical examination, but you do not need to keep a copy of the examination on you.
Employers cannot permit motor vehicles to be operated when the driver's ability or alertness is impaired due to fatigue, illness, or any other reason.
Drivers may not possess or use any prohibited drugs, amphetamines, or other substances that could jeopardize the safe operation of a motor vehicle.
Drivers may not use, possess, or have any measurable amount of detectable alcohol while driving or while on duty. They are also prohibited from consuming alcoholic beverages within four hours of going on duty.
Drivers violating these rules must be placed out of service for twenty-four hours.
The following emergency equipment must be carried on all vehicles in the proper place and ready for use: (1) one fire extinguisher (Type 5BC or larger: properly filled, accessible, and securely mounted); (2) three emergency bi-directional reflective triangles, fuses, or flares; and (3) one spare fuse or other overload protective device for each type and size used.
This part of the regulation (Part 393) also details the requirements for lighting devices, reflectors, electrical equipment, brakes, glazing/window construction, fuel systems, coupling devices and towing methods, emergency equipment, protection against shifting or falling cargo, tires, mirrors, horns, rear end projection, loads, and seat belts.
Inspection and Maintenance
Motor carriers must systematically inspect, repair, and maintain all their vehicles.
Every driver must complete a written vehicle inspection report at the end of each workday on each vehicle operated. Before dispatching the vehicle, the owner must certify on the report that defects, if any, have been corrected or are unnecessary. The report must be kept for ninety days.
Owners operating only one motor vehicle are exempt from this requirement.
Vehicles not passing inspection by enforcement officers and because their condition might cause an accident or breakdown must be taken out of service until repairs are made.
Hours of Service Limitations
The hours of service rules prohibit drivers from driving
More than ten hours following eight consecutive hours off-duty
For any period after being on duty fifteen hours following eight hours off-duty
After having been on-duty more than sixty hours in any seven consecutive days
After having been on-duty more than seventy hours in any period of eight consecutive days (for carriers that operate seven days a week)
These rules have been a source of contention for agricultural retailers and other farm suppliers who were able to win a partial exemption in late 1995.
The law now exempts drivers transporting agricultural commodities or farm supplies for agricultural purposes within a state from the rules under these two conditions:
Transportation is limited to a 100-mile radius from the source of the commodities or the distribution point.
Transportation occurs during the state's planting and harvest seasons as determined by each state.
Violations of the federal Motor Carrier Safety Regulation carry fines ranging from $1,000 to $11,000 per violation, depending on the severity of the offense.
