What the CDL English proficiency bill requires
The Federal Motor Carrier Safety Administration (FMCSA) requires that anyone holding a commercial driver's license (CDL) be able to read, speak, and understand English well enough to operate a commercial vehicle safely. This is a federal rule, not something that varies by state. The requirement exists because CDL holders must understand road signs, communicate with dispatchers and law enforcement, and follow written safety regulations.
Most states test English proficiency as part of the standard CDL written exam and the road test. If you can pass those tests, you meet the requirement. However, some states have passed additional bills or rules that set a higher bar or create a separate English proficiency test. The specifics depend on which state you are in and when you took your test.
The reason these bills exist is that the federal government does not set a single standardized English test for CDL holders — it leaves the method up to each state. Some states decided their existing tests were not rigorous enough and created their own proficiency standards or exams.
Key Takeaways
- Federal law requires CDL holders to read, speak, and understand English, but each state decides how to test this.
- Most states use the written CDL exam and road test to measure English proficiency; passing both shows you meet the standard.
- Some states have passed separate bills requiring an additional English proficiency test or raising the bar for passing the written exam.
- If you are renewing your CDL or explore for a new one, contact your state's Department of Motor Vehicles to learn what English proficiency test or score your state requires.
How states test English proficiency for CDL holders
The written CDL exam itself is an English proficiency test. You must read and understand traffic laws, safety regulations, and road signs — all in English. The exam is offered in English only in most states, though a few states offer it in other languages with an interpreter present. If you pass the written exam, you have shown you can read and understand English at the level needed for the job.
The road test (also called the skills test) is the second measure. You must communicate with the examiner, understand their instructions, and demonstrate that you understand road signs and traffic rules. An examiner who cannot understand you, or who cannot understand your responses, will note that in their report.
Beyond these two standard tests, some states have created their own English proficiency requirements. For example, a state might require a minimum score on the written exam, or might require you to pass a separate English reading or speaking test before you can take the CDL exam. A few states use the Test of English as a Foreign Language (TOEFL) or a similar standardized test.
Which states have passed English proficiency bills
Several states have passed bills or rules that go beyond the federal minimum. However, the details change frequently as states update their rules, and some bills are proposed but not yet in effect. Rather than list specific states here (which could become outdated), the most reliable way to find out what your state requires is to contact your state's Department of Motor Vehicles directly.
When you call or visit your state DMV website, ask: "What English proficiency test or score does my state require for a CDL?" They can tell you whether you need to pass only the standard written and road tests, or whether your state has an additional requirement. They can also tell you what score you need on the written exam, or whether you need to pass a separate test.
If you are explore for your first CDL, renewing an existing one, or adding a new endorsement, the requirement may be different depending on your situation. Your state DMV can clarify which rule applies to you.
What happens if you do not meet the English proficiency standard
If you cannot pass the written CDL exam because you do not understand the English well enough, you will not receive your CDL. You can retake the exam, but you must pass it to move forward. Some states allow you to take the exam in your native language with an interpreter, but this is not available everywhere — you have to ask your state DMV whether this option exists.
If you are already a CDL holder and your state passes a new English proficiency requirement, the rule usually applies to new applicants or to drivers renewing their license. Existing CDL holders are often grandfathered in under the old rule, meaning they do not have to meet the new standard. However, this varies by state, so check with your DMV if you are concerned about a new rule.
If you fail the road test because the examiner cannot understand you or believes you cannot understand English-language instructions, you will not pass that test. You can retake it, but you must demonstrate English proficiency to pass.
How to prepare for English proficiency testing
If English is not your first language, the best preparation is to study the CDL manual for your state in English. Most state DMVs publish the manual online for free, and you can read it as many times as you need. Focus on learning the vocabulary related to driving, road signs, and safety — words like "hazard," "brake," "merge," and "yield."
Practice taking sample CDL exams online. Many websites offer free practice tests that use the same format and language as the real exam. Taking these tests repeatedly helps you get used to reading and understanding the questions under time pressure.
If your state offers the exam with an interpreter, you can ask about that option when you register. However, keep in mind that even with an interpreter, you still need to understand English well enough to operate the vehicle safely — the interpreter is only for the test itself, not for your job as a driver.
Some community colleges and adult education programs offer English classes specifically for people preparing for the CDL exam. These classes teach the vocabulary and reading skills you need. If you live near a community college, ask whether they offer this type of class.
The difference between federal requirements and state bills
The federal government requires English proficiency but does not create a single test for it. The FMCSA leaves it to each state to decide how to measure proficiency. This is why you see variation from state to state.
When a state passes an English proficiency bill, it is usually because the state legislature decided that the federal standard — passing the written and road tests — was not strict enough. The state then creates its own additional test or raises the bar for the written exam score. This is the state's right under federal law.
The downside is that a driver who moves from one state to another may find that their CDL is valid in the new state, but they would have to meet different English proficiency standards if they wanted to renew it there. This is why it is important to know what your current state requires.
Frequently Asked Questions
Can I take the CDL exam in a language other than English?
Most states offer the exam only in English. A few states allow you to take it with an interpreter present, but you have to request this when you register. Contact your state DMV to ask whether this option is available where you live. Even if an interpreter is allowed for the test, you still need to demonstrate English proficiency on the road test.
What if I pass the written exam but fail the road test because of English?
You can retake the road test. Before you do, practice communicating in English with a native speaker or a driving instructor who can give you feedback. The examiner needs to understand your responses and be confident that you understand their instructions. If language is the barrier, focused practice on driving vocabulary and listening skills will help.
Do I have to meet English proficiency requirements to renew my CDL?
If you already hold a CDL, most states do not require you to retake the written exam when you renew — you only need to pass a vision and medical check. However, if your state has recently passed a new English proficiency bill, ask your DMV whether it applies to renewals or only to new applicants.
What is the TOEFL and do I need it for my CDL?
The TOEFL is a standardized English test used for college admission and work visas. A few states have adopted it as part of their CDL English proficiency requirement, but most have not. Check with your state DMV to see whether TOEFL is required where you live.
Can I get a CDL if English is my second language?
Yes. You must meet your state's English proficiency standard, but that standard is designed to measure whether you can safely operate a commercial vehicle — not whether you are a native English speaker. Many CDL holders speak English as a second language. If you can pass the written and road tests, you can get your CDL.
