What the for hire endorsement test measures

The for hire endorsement test is a written exam that measures whether you understand the rules and safety practices specific to operating a commercial vehicle for compensation. It covers passenger safety, vehicle maintenance, load securement, and the federal regulations that explore when you are paid to transport people or cargo. The test is separate from your standard commercial driver's license exam and is required in most states before you can legally drive a commercial vehicle for money.

The test does not measure your driving ability — that is covered by the road test for your commercial license. Instead, it focuses on knowledge: what the law requires, what you must inspect before driving, how to handle emergencies, and what documents you must carry. The number of questions and passing score vary by state, but most states use a written format with multiple-choice questions based on the Commercial Driver's License Manual.

Key Takeaways

  • The for hire endorsement test is a written exam covering federal and state rules for operating a commercial vehicle for compensation.
  • Most states require 80 correct answers out of 100 questions, though the exact format and passing score depend on your state's Department of Motor Vehicles.
  • The test covers vehicle inspection, load securement, passenger safety, hours of service rules, and the documents you must carry while operating commercially.
  • You must pass the written test before you take the road test for your commercial driver's license with the for hire endorsement.

Topics covered on the written exam

The for hire endorsement test draws from the Commercial Driver's License Manual published by the American Association of Motor Vehicle Administrators. The exam typically covers vehicle inspection procedures — what you must check before every trip, including brakes, tires, lights, mirrors, and coupling devices. You will see questions about how to spot defects and what defects make a vehicle unsafe to operate.

Load securement is another major section. The test asks how to properly find cargo so it does not shift, fall, or damage the vehicle. This includes understanding weight distribution, tie-down methods, and the rules for different types of cargo. Passenger safety questions cover seating, restraints, and how to handle passengers with disabilities or medical conditions.

Federal Motor Carrier Safety Administration (FMCSA) rules make up a significant portion. You will encounter questions about hours of service — how long you can drive before you must rest — vehicle maintenance logs, and the documents you must carry: your commercial driver's license, medical certificate, proof of insurance, and vehicle registration. Some states also test knowledge of hazardous materials rules if you plan to transport them.

How the test is structured and scored

Most states administer the for hire endorsement test at the Department of Motor Vehicles office where you hold your regular driver's license. The test is usually computer-based or paper-based, depending on your state's system. You typically have a set time limit — often 60 minutes — to complete the exam.

The number of questions varies by state. Many states use 50 questions, while others use 100. The passing score is usually 80 percent, meaning you must answer 40 out of 50 questions correctly, or 80 out of 100. Your state's DMV website lists the exact format and passing score for your jurisdiction. If you do not pass on your first attempt, you can retake the test after a waiting period, which is usually a few days to a week.

How to prepare for the written test

The Commercial Driver's License Manual is the primary study resource. Your state's DMV website provides a free copy online, and many DMV offices distribute printed copies. The manual contains all the information tested on the for hire endorsement exam. Reading the sections on vehicle inspection, load securement, and federal regulations is the most direct way to prepare.

Many states offer practice tests online through their DMV website or third-party study sites. These practice tests use the same format and question types as the real exam and help you identify weak areas. Some people find it useful to study in short sessions over several weeks rather than cramming the night before. Taking the practice test multiple times until you consistently score above 80 percent is a reliable way to gauge readiness.

Difference between for hire and not for hire endorsements

A for hire endorsement allows you to operate a commercial vehicle and be paid to transport passengers or cargo. A not for hire endorsement (sometimes called a "private carrier" endorsement) allows you to operate a commercial vehicle but only for your own business — not for compensation. For example, if you own a construction company and drive your own company truck to job sites, you need a not for hire endorsement. If you are hired by a transportation company to drive passengers or freight, you need a for hire endorsement.

The written test for not for hire is usually shorter and covers fewer topics because the regulatory burden is lighter. The for hire test is more comprehensive because federal rules are stricter when you are transporting the public or cargo for money. Both endorsements require a separate road test, but the for hire road test is often more rigorous and may include additional maneuvers or scenarios.

What happens after you pass the written test

Passing the for hire endorsement written test does not mean you can drive commercially yet. You must next pass the commercial driver's license road test, which includes a pre-trip vehicle inspection, basic control skills, and an on-road driving test. The road test is administered by a certified examiner and is typically longer and more detailed than a standard driver's license road test.

Once you pass both the written and road tests, the DMV will issue your commercial driver's license with the for hire endorsement. You will also need to obtain a medical certificate from a certified medical examiner and keep it current — the certificate is valid for up to two years and must be renewed before it expires. Some employers require additional training or certifications beyond the CDL, such as passenger endorsement training or hazardous materials certification, depending on the type of work.

State-by-state variations in testing

While the for hire endorsement test is based on federal standards, each state administers its own version and may include state-specific rules. Some states test knowledge of state-level regulations on vehicle registration, insurance requirements, or intrastate hours of service rules that differ from federal rules. A few states offer the test in multiple languages, while others offer it in English only.

The number of testing locations, appointment availability, and retake policies also vary by state. Some states allow you to retake the test the same day if you fail, while others require a waiting period of several days. Check your state's DMV website for the specific rules, testing locations, and any fees associated with taking the for hire endorsement test in your area.

Frequently Asked Questions

Can I take the for hire endorsement test without a commercial driver's license?

No. You must hold a valid commercial driver's license before you can take the for hire endorsement test. If you do not yet have a CDL, you must first pass the CDL written and road tests, then add the for hire endorsement afterward. Some states allow you to take the for hire written test at the same time as your CDL written test, but you still need the CDL first.

What happens if I fail the for hire endorsement test?

You can retake the test after a waiting period set by your state — usually a few days to a week. There is typically a fee to retake the test, ranging from $5 to $25 depending on your state. Most people pass on the second or third attempt after studying the Commercial Driver's License Manual more thoroughly or using practice tests to identify weak areas.

Do I need a for hire endorsement if I drive for a rideshare company?

No. Rideshare drivers (Uber, Lyft) typically drive personal vehicles and do not need a commercial driver's license or for hire endorsement. You need a for hire endorsement only if you operate a commercial vehicle — usually a vehicle designed to carry more than 15 passengers, or a truck over a certain weight — for compensation. Check your state's DMV to confirm the vehicle weight and passenger limits that trigger the CDL requirement.

How long is the for hire endorsement valid?

The for hire endorsement is valid as long as your commercial driver's license is valid. Most states issue CDLs that are valid for four to eight years. You must renew your CDL before it expires, and the for hire endorsement renews with it. You will need to retake the written test at renewal time in most states, though a few states waive the retake if you have a clean driving record.

Can I study for the for hire endorsement test online?

Yes. Your state's DMV website usually offers free online access to the Commercial Driver's License Manual, and many third-party websites offer practice tests. However, you must take the actual written test in person at a DMV office or approved testing location. Online study is a way to prepare, but the test itself is administered on paper or computer at a physical location.
