Commercial Drivers Drivers employed by interstate motor carriers and HM intrastate motor carriers with an active U.S. DOT number.
Commercial Motor Vehicles Involved Crashes The number of commercial motor vehicles involved in a NGA reportable crash. In MCMIS, an NGA reportable crash must involve a truck (a vehicle designed, used, or maintained primarily for carrying property, with a gross vehicle weight rating or gross combination weight rating of more than 10,000 lbs.) or bus (a vehicle with seats for at least nine people, including the driver).
Commercial Motor Vehicles Involved in Fatal Crashes The number of commercial motor vehicles involved in a crash where one or more persons dies within 30 days of the crash. The fatality does not have to occur at the scene of the crash. It includes any person involved in the crash, including pedestrians and bicyclists, as well as occupants of the passenger cars and trucks.
Commercial Motor Vehicles Involved in Non-Fatal Injury Crashes The number of commercial motor vehicles involved in a crash where one or more persons has non-fatal injuries requiring transportation by a vehicle for the purpose of obtaining immediate medical attention.
Commercial Motor Vehicles Involved in Non-Fatal Crashes The number of commercial motor vehicles involved in a crash where one or more persons has non-fatal injuries requiring transportation by a vehicle for the purpose of obtaining immediate medical attention; or one or more of the vehicles were towed away from the scene due to "disabling damage." The towed vehicle need not be the truck or bus involved in the crash.
Commercial Motor Vehicles Involved in Towaway Crashes The number of commercial motor vehicles involved in a crash where one or more of the vehicles were towed away from the scene due to "disabling damage". The towed vehicle need not be the truck or bus involved in the crash.
Commercial Zone The area around a port of entry at the U.S.-Mexico border in which motor carriers, domiciled in Mexico, with an approved Form OP-2 can operate.
Commercial Zones Inspections Roadside inspections that occurred in a county along the US-Mexican border where there is a border crossing location.
Compliance Reviews Compliance reviews consist of federal and state compliance reviews. A compliance review is an on-site examination of motor carrier operations, such as drivers' hours of service, maintenance and inspection, driver qualification, commercial drivers license requirements, financial responsibility, crashes, hazardous materials, and other safety and transportation records to determine whether a motor carrier meets the safety fitness standard. A compliance review may be conducted in response to a request to change a safety rating, to investigate potential violations of safety regulations by motor carriers, or to investigate complaints or other evidence of safety violations. The compliance review may result in the initiation of an enforcement action.
Conditional A safety rating received as a result of a Compliance Review. A Conditional rating is defined as: a motor carrier does not have adequate safety management controls in place to ensure compliance with the safety fitness standard that could result in occurrences listed in § 385.5 (a) through (k).
CVSA Decals If a vehicle passes a roadside inspection, a CVSA decal is obtained from the certified government employee who performs the inspection. The term "certified" means the government employee performing inspections and/or affixing CVSA decals must have first successfully completed a training program approved by the Commercial Vehicle Safety Alliance. Decals, when affixed, shall remain valid for a period not to exceed three consecutive months. Vehicles displaying a valid decal generally will not be subject to reinspection. Reinspection of a vehicle bearing a current and valid CVSA decal is contemplated under the following circumstances:
  • A North American Commercial Vehicle Critical Safety Item or out-of-service violation is detected.
  • When a Level IV (Special Inspection) exercise is involved.
  • When a statistically based random inspection technique is being employed to validate an individual jurisdiction or regional out-of-service percentage, or
  • When reinspections are conducted to maintain CVSA inspection quality assurance.

Hazardous Material (HM) HM is any substance or material which has been determined by the U.S. Secretary of Transportation to be capable of posing an unreasonable risk to health, safety, and property when transported in commerce and which has been so designated under regulations of the U.S. Department of Transportation. Most vehicles carrying HM are required by law to conspicuously display a placard indicating the class, type, or the specific name of the HM cargo. In addition, vehicles transporting HM in tank cars, cargo tanks, or portable tanks are required to display the four-digit hazardous materials number assigned to the specific material on placards or orange panels.
HM Inspections Roadside inspections (Levels I, II, III, and VI when HM is present) conducted on interstate and intrastate motor carriers.
HM Inspections w/OOS Violations Roadside inspections (Levels I, II, III, and VI when HM is present) conducted on interstate and intrastate motor carriers that resulted in at least one OOS violation reported.
HM OOS Rate The percentage of roadside inspections (Levels I, II, III, and VI when HM is present) that resulted in OOS orders for interstate motor carriers and HM intrastate motor carriers with an active U.S. DOT number.
HM OOS Violations A carrier is determined to be non-compliant with a specific HMR that has been identified as a serious violation and therefore results in a HM OOS order. The violation must be corrected before the affected driver or vehicle can return to service.

Inspection Levels The North American Standard Truck Inspection procedures comprise six levels of inspections, Levels I-VI.) For a comprehensive description of each level click here. (Review the FMCSA Regulations for detailed definitions of the regulations.)
Inspections An inspection occurs when a Motor Carrier Safety Assistance Program (MCSAP) inspector conducts an examination on individual commercial motor vehicles and drivers to determine if they are safe to operate by determining if they are in violation of the Federal Motor Carrier Safety Regulations (FMCSR) and Hazardous Materials Regulations (HMR). Serious violations result in driver or vehicle OOS orders, which must be corrected before the affected driver or vehicle can return to service. Drivers that ignore existing OOS orders (returning to service without taking the proper corrective action) are cited for violating an OOS order. Moving violations also may be recorded in conjunction with an inspection.
Inspections with Traffic Enforcement Violations The number of inspections that occurred as a result of a traffic enforcement stop. The Traffic Enforcement program involves the enforcement of twenty-one moving and non-moving driver violations, which are included in the driver violation portion of the roadside inspection procedures. Only those traffic enforcements that result in a subsequent roadside inspection are fundable by MCSAP. If a roadside inspection results in only a Drug or Alcohol related violation, then it is excluded as a Traffic Enforcement Type Inspection.
Level I Inspections (North American Standard Inspection) An inspection that includes examination of driver's license, medical examiner's certificate and waiver, if applicable, alcohol and drugs, driver's record of duty status as required, hours of service, seat belt, vehicle inspection report, brake system, coupling devices, exhaust system, frame, fuel system, turn signals, brake lamps, tail lamps, head lamps, lamps on projecting loads, safe loading, steering mechanism, suspension, tires, van and open-top trailer bodies, wheels and rims, windshield wipers, emergency exits on buses, and hazardous materials (HM) requirements, as applicable.
Level II Inspections (Walk Around Driver/Vehicle Inspection) An examination that includes each of the items specified under the North American Standard Inspection. As a minimum, Level II inspections must include examination of: driver's license, medical examinees certificate and waiver, if applicable, alcohol and drugs, driver's record of duty status as required, hours of service, seat belt, vehicle inspection report, brake system, coupling devices, exhaust system, frame, fuel system, turn signals, brake lamps, tail lamps, head lamps, lamps on projecting loads, safe loading, steering mechanism, suspension, tires, van and open-top trailer bodies, wheels and rims, windshield wipers, emergency exits on buses, and HM requirements, as applicable. The walk-around driver/vehicle inspection generally includes only those items which can be inspected without physically getting under the vehicle.
Level III Inspections (Driver Only Inspection) A roadside examination of the driver's license, medical certification and waiver, if applicable, driver's record of duty status as required, hours of service, seat belt, vehicle inspection report, and HM requirements, as applicable.
Level IV Inspections (Special Study) Inspections under this heading typically include a one-time examination of a particular item. These examinations are normally made in support of a study or to verify or refute a suspected trend.
Level V Inspections (Vehicle Only Inspection) An inspection that includes each of the vehicle inspection items specified under the North American Standard Inspection (Level I), without a driver present, conducted at any location.
Level VI Inspections (North American Standard Inspection for Transuranic Waste and Highway Route Controlled Quantities (HRCQ) of Radioactive Material) An inspection for select radiological shipments, which include inspection procedures, enhancements to the North American Standard Level I Inspection, radiological requirements, and the North American Standard Out-of-Service Criteria for Transuranic Waste and Highway Route Controlled Quantities (HRCQ) of Radioactive Material.

As of January 1, 2005, all vehicles and carriers transporting highway route controlled quantities (HRCQ) of radioactive material are regulated by the U.S. Department of Transportation and required to pass the North American Standard Level VI Inspection.

Previously, U.S. Department of Energy (DOE) voluntarily complied with the North American Standard Level VI Inspection Program requirements.

Select radiological shipments include highway route controlled quantities (HRCQ) of radioactive material as defined by Title 49 CFR Section 173.403. And, because only a small fraction of transuranics are HRCQ, DOE has decided to include its transuranic waste shipments in the North American Standard Level VI Inspection Program.
Mexican Domiciled Carriers with Limited Authority Beyond the Commercial Zone Mexican domiciled carriers with limited authority beyond the commercial zone are based on the Federal Motor Carrier Safety Administration's most recent carrier list. Inspection and crash data for carriers with limited authority beyond the commercial zone may have occurred in the commercial zone or beyond.
Mexican Domiciled Carriers in the Commercial Zone Mexican domiciled carriers in the commercial zone are identified differently for inspection versus crash data. In the case of inspections, domicile information for a carrier is based on census address information when the DOT number is available. When an inspection does not have a DOT number associated with it, the domicile information for a carrier provided at the time of the inspection is used. For crashes, domicile information for the carrier is based on the domicile information provided at the time of the crash. Inspections or crashes must have occurred in the commercial zone. Data for Mexican domiciled carriers in the commercial zone excludes the data of those carriers with limited authority beyond the commercial zone.

Safety Rating A motor carrier receives a safety rating when the safety investigator conducts an on-site review of the carrier's compliance with the Federal Motor Carrier Safety Regulations and the Hazardous Materials Regulations. The investigator reviews records, evaluates roadside vehicle inspection data, and crashes to determine whether a motor carrier meets the Safety Fitness standard. (Review the FMCSA Regulations for a detailed definition of a safety rating.)
Satisfactory A safety rating received as a result of a compliance review. A Satisfactory rating is defined as: a motor carrier has in place and functioning adequate safety management controls to meet the safety fitness standard prescribed in § 385.5 (a) through (k). Safety management controls are adequate if they are appropriate for the size and type of operation of the particular motor carrier.
Serious Traffic Violations Includes moving violations of a serious nature along with drug and alcohol violations.

Traffic Enforcement The Traffic Enforcement program involves the enforcement of twenty-one moving and non-moving driver violations, which are included in the driver violation portion of the roadside inspection procedures. Only those traffic enforcements that result in the performance of a subsequent roadside inspection are included in the MCSAP program. If a roadside inspection results in only a Drug or Alcohol-Related violation then it is excluded as a Traffic Enforcement Type Inspection.
Unsatisfactory A safety rating received as a result of a compliance review. An Unsatisfactory rating is defined as: a motor carrier does not have adequate safety management controls in place to ensure compliance with the safety fitness standard which has resulted in occurrences listed in § 385.5 (a) through (k). Motor carriers receiving an "unsatisfactory safety rating" may be subject to the provisions of Section 385.13.
Value Imports: "VALUE" refers to the U.S. Customs value or the value of merchandise for duty purposes. It is usually the selling price in the foreign country of origin. It excludes freight costs, insurance, and other charges incurred in bringing the merchandise from the foreign country to the United States.

Exports: "VALUE" refers to the value of the merchandise, usually the selling price, plus insurance, and freight at the U.S. port of export.
