Who Must Obtain a CDL
Idaho's Commercial Driver's License (CDL) Program is designed to improve safety on our highways while meeting federal requirements for testing and licensing of all commercial drivers. You must have a CDL to operate any of the following commercial motor vehicles (CMV):

Combination vehicle with a gross combination weight rating (GCWR) of 26,001 or more pounds, provided that the gross vehicle weight rating (GVWR) of the towed unit is greater than 10,000 pounds
Single vehicle with a gross vehicle weight rating of 26,001 or more pounds
Vehicle designed to transport 16 or more persons (including the driver)
School bus (Yellow and black bus of any size transporting children to school or school events)
Any size vehicle that requires hazardous material placards

Gross vehicle weight rating (GVWR) is the manufacturer's assigned weight rating for the vehicle (truck, bus, or trailer), not the vehicle registered weight. On trucks, the GVWR is usually found on a plate or sticker inside the driver's door. On trailers, it may be found anywhere but is commonly found on the front of the trailer on the trailer tongue or frame. For Idaho, in the absence of a GVWR, the actual weight of the vehicle plus its heaviest load is considered to be the GVWR. The sum of the GVWR of the tires can also be used to determine approximate GVWR. Other states may use other definitions.

Gross combined weight rating (GCWR), is figured by adding the GVWR of each unit of a combination vehicle.

Exemptions from CDL Requirements

Even if your vehicle is a commercial vehicle according to the definition above, you may qualify for one of the CDL exemptions. There are four categories of CDL exemptions.

Recreational vehicle exemption – applies to drivers of vehicles used exclusively to transport personal possessions or family members for non-business or recreational purposes.

Military vehicle exemption – applies to military vehicle operators who are considered active-duty military personnel and to civilians who are required to wear uniforms and are subject to the Code of Military Justice.

Emergency vehicle exemption – applies to drivers of firefighting or other emergency equipment used in response to emergencies involving the preservation of life or property.

Farm vehicle exemption – applies to drivers of farm vehicles, including family members and farm hands, under certain conditions only. The farm exemption applies to drivers of farm vehicles which are:

Controlled and operated by the farmer,
Used to transport agricultural products, supplies, and machinery to or from a farm,
Not used in common or contract carrier operations, and
Not driven more than 150 miles ("as the crow flies") from the farm.

The farm exemption is intended for small farm-to-market operations only. Unless Idaho is involved in a reciprocity agreement with the other state(s), the farm exemption does not extend beyond the boundaries of Idaho. It does not include farmers who are transporting other farmers' products if they are receiving any compensation for the services.

CDL License Classes

There are three classes of commercial driver's licenses: Class A, B and C. Drivers of vehicles that do not fall in Classes A, B, or C will be issued Class D (non-commercial) licenses.

Class A – Combination vehicles with a gross combination weight rating (GCWR) of 26,001 or more pounds, provided the GVWR of the vehicle(s) being towed is greater than 10,000 pounds. Drivers with a Class A license may, with the proper endorsements, operate vehicles requiring a Class B, C or D license.

Class B – Single vehicles with a GVWR of 26,001 or more pounds, or any such vehicle towing a vehicle 10,000 pounds GVWR or less. A driver with a Class B license may, with the proper endorsements, operate vehicles requiring a Class C or D license.

Class C – Vehicles with a GVWR or GCWR less than 26,001 pounds. Class C is strictly for vehicles designed to carry 16 or more people (including the driver), or carrying hazardous materials requiring the vehicle to display placards. A driver with a Class C license may also operate vehicles requiring a Class D license.

Endorsements

You must have the appropriate endorsement on your CDL if you haul hazardous materials, pull double or triple trailers, or drive tank or passenger vehicles.

Double/Triple (T) – Required for drivers of vehicles pulling two or three trailers. (A dolly or load divider, sometimes referred to as a "jeep," is considered to be one trailer.)

Hazardous materials (H) – Required for drivers of vehicles transporting hazardous materials requiring placards per the Hazardous Materials Transportation Act. A written test and Transportation Security Administration threat assessment clearance (background check) are required to obtain the hazmat endorsement, and at each driver license renewal.

Passenger (P) – Required for drivers of vehicles designed to carry 16 or more passengers including the driver. Both written and skills tests are required to obtain this endorsement.

School Bus (S) – Required for drivers of vehicles used to transport preprimary, primary or secondary school students from home to school, from school to home, or to and from school-sponsored events. Drivers of school buses must have both the Passenger and School Bus endorsements. Both written and skills test are required to obtain this endorsement.

Tank vehicles (N) – Required for drivers of any commercial motor vehicle that is designed to transport any liquid or gaseous materials within a tank or tanks having an individual rated capacity of more than 119 gallons and an aggregate rated capacity of 1,000 gallons or more that is either permanently or temporarily attached to the vehicle or the chassis. A commercial motor vehicle transporting an empty storage container tank, not designed for transportation, with a rated capacity of 1,000 gallons or more that is temporarily attached to a flatbed trailer is not considered a tank vehicle.

Tank Vehicles/Hazardous Materials (X) – The X endorsement represents the combination of both the tank vehicles (N) and hazardous materials (H) endorsements. A CDL may show either an X or an N and H on the endorsement line of the license.

Restrictions

K Restriction – Intrastate Operation only. If a driver plans to operate commercial vehicles only in Idaho, the (K) restriction will be placed on their driving record. This restriction will also be placed on all 18, 19, and 20 year old CDL holders.

L Restriction – Prohibits driving of vehicles with air brakes. The CDL will carry this restriction unless you pass an air brakes knowledge test and a skills test in a vehicle equipped with air brakes.

M Restriction – Except Class A Bus – The (M) restriction prohibits a driver with a passenger endorsement from operating a Class A bus if a Class A bus was not used for the skills test. A driver with a Class A CDL who also has a (P) endorsement will typically have the (M) restriction. Class A busses are not commonly found in the United States.

N Restriction – Prohibits the driver from operating Class A or B passenger vehicles (buses). A Class A or B CDL with the passenger endorsement will carry this restriction unless the driver obtains a passenger endorsement by successfully completing a skills test in a Class B passenger vehicle (bus).

O Restriction – Prohibits the driver from operating a tractor-trailer combination connected by a fifth wheel. If a driver performs the skills test in a combination vehicle for a Group A CDL with the power unit and towed unit connected with a pintle hook or other non-fifth wheel connection, the O restriction will be added to the CDL. A skills test in a tractor-trailer combination connected by a fifth wheel will be required to remove the O restriction.

P Restriction – A CDL instruction permit holder with a P or P and S endorsement is prohibited from operating a CMV carrying passengers, other than Federal/State auditors and inspectors, test examiners, other trainees, and the CDL holder accompanying the permit holder.

V Restriction – If the State is notified by Federal Motor Carrier Safety Administration or a registered doctor that the driver has been issued a medical variance, the State must indicate the existence of such a medical variance on the CDL document.

X Restriction – A CDL instruction permit holder with an N endorsement may only operate an empty tank vehicle and is prohibited from operating any tank vehicle that previously contained hazardous materials that has not been purged of any residue.

Z Restriction – The driver is restricted from operating a CMV equipped with any braking system operating fully on the air brake principle. If an applicant performs the skills test in a vehicle equipped with air over hydraulic brakes, the Z restriction must be placed on the CDL. For the purposes of the skills test and the restriction, air over hydraulic brakes includes any braking system operating partially on the air brake and partially on the hydraulic brake principle. A full skills test is required to remove the Z restriction.

Seasonal CDL

A Seasonal CDL is available to qualified seasonal drivers for certain farm-related service industries such as custom harvesters, farm retail outlets and suppliers, agri-chemical businesses, and livestock feeders. The Seasonal CDL is only valid within 150 miles of the business or farm being serviced. The Seasonal CDL is valid (with a Class D license) for 180 days in a 12 month period, and can only be obtained twice in a lifetime. The Seasonal CDL is not valid for driving Class A (combination) vehicles or passenger vehicles designed to carry 16 or more people including the driver. The Seasonal CDL is not valid for driving vehicles carrying hazardous materials requiring placards except for diesel fuel in quantities of 1,000 gallons or less, liquid fertilizers in vehicles or implements of husbandry with total capacities of 3,000 gallons or less, or solid fertilizers that are not mixed or transported with any organic substance.

How to Obtain an Idaho CDL

To apply for a CDL, you must be at least 18 years old and either have a valid Idaho non-commercial license (Class D) or have passed all tests required to obtain one. You may be able to take your Class D license tests and your CDL tests at the same time. However, you must have one year of licensed driving experience in order to obtain a CDL.

If you want to obtain a CDL, study Idaho's "Commercial Driver's License Manual" which may be obtained from a county driver's license Office. The manual is also available online in PDF format here: http://itd.idaho.gov/wp-content/uploads/2016/06/cdl_manual.pdf. This manual provides you with the information necessary to pass all CDL written tests. Information regarding the skills test requirements is also included.

To apply for your CDL, go to your county driver's license office. Take your current driver's license, Social Security card, proof of Idaho residence and money to pay your fees. ALL applicants will be required to provide proof of lawful presence in the United States; for most applicants a state certified birth certificate or a U.S. Passport will work. If the name on your birth certificate is different than the name on your driver's license, you will need to provide additional documentation.

You will be asked if you are subject to and in compliance with the requirements of Part 391 of the Federal Motor Carrier Safety Regulations (Qualifications of Drivers). You will be asked to declare (self-certify) what type of driving you intend to do: Interstate or Intrastate (within Idaho only) and whether the type of driving you plan to do will require a DOT Medical card or not. When applying for your CDL, your driving record will be checked, fees will be collected, and you are required to pass the vision and knowledge tests.

After passing the required written tests for the class of license you wish to obtain, you must purchase a Commercial Learner's Permit. You must wait 14 days from the date you obtain your CLP before you can take a skills test. During that time, practice and study for your skills test.

You must make an appointment with a CDL Skills Tester to take the skills test. A list of Examiners is available at the County DMV and online by clicking on the "Skills Testers" tab. Some testers have vehicles that you can rent. When you go to the skills tester, you will need to take your Driver's License, your Commercial Learner's Permit, and proof of insurance and registration for your test vehicle. Your vehicle must be in good working condition for the test.

The skills test has three parts: the vehicle inspection, the basic control skills test, and the road test. The skills test will take two to three hours to complete and must be taken in a vehicle that is representative of the license class you wish to obtain. If the vehicle used for the test is not equipped with air brakes, your CDL will show a restriction stating that you are not licensed to operate vehicles equipped with air brakes.

After you have passed all required written and skills tests, you do not have the authority to operate a commercial vehicle until you obtain your CDL from the County DMV. You will be issued a temporary license from your county driver's license office and your permanent license will be sent to you by US Mail. It is very important your mailing address is current and accurate. If you move after your CDL is issued, you must notify Idaho Transportation Department of your new address.

All test results remain valid for one year. If the appropriate license is not issued within the one-year period, the tests must be re-taken. If you do not pass a test, you must wait three (3) days before retaking the test. Test fees must be paid again.

CDL tests are not required at renewal time, with the exception of the Hazardous Materials test which must be passed prior to each renewal.

Commercial Learner's Permit (CLP)

A Commercial Learner's Permit is required to obtain a CDL by federal law. The permit allows you to practice driving a large commercial vehicle on public roads. This permit is obtained by taking the required written tests for the type of vehicle you will operate. A CLP is valid for 180 days, and may be renewed one time prior to expiration without re-testing. You must be at least 18 years old, hold a valid Idaho Class D driver's license, have at least one year of driving experience to obtain a CLP. To use the permit, you MUST be accompanied by a driver properly licensed to operate the vehicle you are driving, and this person MUST occupy the seat beside the driver or the row behind the driver in a bus.

Other Laws Affecting CDL Drivers

Most drivers subject to CDL requirements are also required to participate in a controlled substance and alcohol random testing program and be enrolled in the Drug and Alcohol Clearinghouse. These requirements include random, reasonable suspicion, post accident, return-to-duty, and follow-up testing for controlled substances and alcohol. Pre-employment controlled substance testing is also required.

CDL holders are subject to the laws affecting all drivers. In addition, there are federal and state laws that specifically affect CDL drivers. Violations of these laws can result in both civil and criminal penalties or may disqualify you from driving commercial vehicles. Following are some important laws:

You cannot have more than one license, and the license you do have must be issued from the state in which you reside. If you move to a new state, you must obtain a CDL from that state within thirty (30) days.
It is your responsibility as an Idaho driver to keep a current address on file with the Idaho Transportation Department (ITD). If you move, you must notify ITD Driver Services in writing of the old and new address within 30 days.
You are required to declare (self-certify) the type of type of driving you intend to do: Interstate or Intrastate (within Idaho only) and whether the type of driving you plan to do requires a DOT Medical card or not.
You are required to submit a copy of your DOT medical card if you are required to have one for the type of driving done in either interstate or intrastate operations.
You must notify the ITD Driver Services within 30 days if you are convicted in any other state of any traffic violation (except parking). This is true no matter what type of vehicle you were driving at the time of the violation.
You must notify your employer within 30 days of a conviction for any traffic violation (except parking). This is true no matter what type of vehicle you were driving.
You must notify your employer if your license is suspended, revoked, or canceled, or if you are disqualified from driving.
When you apply for a commercial driving job, you must give your potential employer information on all driving jobs you have held for the past 10 years.
No one can drive a commercial motor vehicle (CMV) without a valid CDL. A court may fine you up to $5000 or put you in jail for breaking this rule.
Your employer may not let you drive a CMV if you have more than one license or if your CDL is suspended, revoked or disqualified. A court may fine the employer up to $5000 or put him/her in jail for breaking this rule.

Commercial Drivers Self-Certification Reporting

Self Certification
Federal DOT Medical Card Requirements

CDL Drivers not Actively Working, Please Note: If a driver holds a valid Idaho CDL, but is not actively driving a commercial vehicle, the driver is not required to maintain a DOT Medical and may certify the driving category as "Excepted Intrastate." However, should a driver decide to operate a commercial vehicle again in one of the "non-excepted" categories, the driver must obtain a current DOT Medical and update their certification to "actively working" before operating a commercial vehicle in a non-excepted category.

Exemption Chart: Under certain circumstances, drivers in the following categories may be exempt from the medical card requirement but NOT from commercial licensing requirements according to FMCSA regulations. This list is a general guide: Transportation by federal, state, and local governments; fire trucks, apiarian industries, intrastate (Idaho) vehicles used to transport farm products, equipment, and supplies; Ag products, livestock, feed, forest products, sand & gravel, wrecker/tow truck, airline shuttle, household goods movers, occasional transport of personal property, ambulance, hearse, taxicab operations.

CDL Disqualifications
In addition to the above laws affecting CDL drivers, you are also subject to CDL disqualification rules and laws. Your CDL privileges may be withdrawn for varying periods of time based on the type of offense committed. The following information identifies the offenses and disqualification periods.
