Quick Answer: CDL Disqualifications in Texas
- A DUI or DWI conviction can trigger a CDL disqualification — typically 1 year for a first offense under federal rules, with a lifetime disqualification possible for a second offense.
- Certain medical conditions may affect your ability to pass a DOT physical exam — which is required for a CDL — but many conditions are manageable with documentation or treatment.
- Some specific criminal convictions affect CDL eligibility itself. Others mainly affect employer hiring, not whether you can hold the license.
- Many people who assume they're disqualified are still eligible. The rules are more specific than most people think.
- Getting a CDL license and getting hired by a trucking company are two different questions — and the answers can differ.
- If you're unsure, get matched with a Texas CDL school — admissions teams can often help you understand your eligibility before you apply.
Important: CDL eligibility depends on federal FMCSA rules, Texas DPS standards, your driving record, medical certification, and individual circumstances. This page is general educational information, not legal advice. Rules and exemption programs change — always verify current standards with a certified DOT medical examiner, Texas DPS, or a licensed attorney for your specific situation. Last updated: March 2026.
Two Separate Questions — Don't Confuse Them
Before going through the disqualification rules, it's important to understand that there are two entirely separate questions many applicants mix together:
Question 1: Can You Hold a CDL?
This is governed by federal FMCSA rules and Texas DPS standards. Certain DUI convictions, criminal offenses, and medical conditions are specified disqualifiers under these rules. This is whether you can be licensed.
Question 2: Will a Company Hire You?
This is governed by each carrier's internal hiring policy and background check standards. An employer may decline to hire someone who is technically eligible to hold a CDL. These are separate decisions with separate standards.
Key takeaway: You may be eligible to hold a CDL license but still face challenges with certain employers — especially those running hazmat or dedicated routes with stricter background requirements. This guide covers CDL license eligibility. Employer hiring standards vary and are not covered by FMCSA rules.
DUI / DWI and CDL Eligibility
A DUI or DWI is one of the most common concerns for CDL applicants. Before paying for training, it helps to understand your full CDL training cost in Texas and review options on our best CDL schools guide. Under federal FMCSA rules, a first DUI conviction typically triggers a 1-year CDL disqualification period. A second conviction can result in a lifetime CDL disqualification. However, the specifics depend on the nature of the offense, the vehicle involved, and how much time has passed.
✕ May Trigger Disqualification
- DUI / DWI in any vehicle — federal rules typically result in a 1-year CDL disqualification from conviction date
- DUI in a commercial vehicle — 1-year disqualification; lifetime on a second offense
- Refusing a breath or blood alcohol test — treated similarly to a DUI under federal rules
- Second DUI or DWI conviction — can result in lifetime CDL disqualification under FMCSA rules
- DUI while transporting hazardous materials — federal rules call for a 3-year disqualification
⚠ May Still Be Eligible
- A single DUI where the disqualification period has passed (typically 1 year from conviction date)
- Older DUI convictions without a second offense on record
- Alcohol-related charges below the DUI threshold (wet reckless, etc.) — depends on specific charge
- Expunged DUI records — varies by state law and circumstances; consult a school or attorney
Example: A Texas applicant with one DUI from several years ago may still qualify after the federal disqualification period ends — especially if there have been no additional offenses and their regular license is active. The key questions are how long ago the conviction occurred and whether any additional disqualifying issues exist. Situations vary; confirm your specific timeline with a CDL school or attorney.
A single older DUI does not automatically end your CDL career. The 1-year disqualification period ends, and many licensed CDL drivers have past DUI convictions on record. If you're unsure about your specific situation, a CDL school admissions team can often help clarify your eligibility before you invest in training.
Had a DUI? You May Still Qualify
Many applicants move forward after the disqualification period ends. Get matched with a Texas CDL school and ask about your specific situation before ruling yourself out.

Medical Conditions and CDL Eligibility
CDL drivers must pass a DOT physical exam performed by a licensed medical examiner. You can also review the full Texas CDL requirements or our guide on how to get a CDL in Texas if you're still early in the process. The examiner determines whether you meet federal commercial driving fitness standards. Many conditions that people assume are automatic disqualifiers are actually manageable with documentation, treatment compliance, or case review.
Vision
Federal standards generally require at least 20/40 vision in each eye with or without correction, and adequate field of vision. Monocular vision (one functional eye) typically does not meet interstate CDL standards, though exemption programs exist. A DOT medical examiner makes the final determination.
Diabetes
Insulin-treated diabetics were previously unable to hold an interstate CDL, but FMCSA now allows qualified applicants to apply for a Federal Diabetes Exemption. Non-insulin-treated diabetes is generally not a disqualifier with proper medical documentation. Requirements vary — confirm with a certified DOT medical examiner.
Blood Pressure & Heart
Uncontrolled hypertension may result in a short-term medical certificate or temporary disqualification. Controlled blood pressure with medication is generally acceptable. Cardiac conditions depend on severity, treatment, and documentation. A DOT medical examiner reviews each case individually.
Epilepsy / Seizures
A history of seizures typically does not meet federal interstate CDL standards unless you've been seizure-free for a substantial period without anti-seizure medication. Exact standards depend on seizure type, history, and federal exemption programs. A DOT medical examiner determines eligibility.
Sleep Apnea
Untreated sleep apnea typically does not meet DOT fitness standards for commercial driving. Drivers who are diagnosed and using a CPAP machine with documented compliance are generally approved after medical review. Bring your compliance data to your DOT physical.
Mental Health
A mental health history does not automatically disqualify you. The DOT physical focuses on current functional ability and whether conditions are controlled, not just diagnosis history. Conditions managed with medication are often acceptable. A certified medical examiner makes the final determination.
Don't assume — get a DOT physical first. A certified DOT medical examiner can tell you whether your specific condition meets commercial driving fitness standards before you spend money on CDL school. Many conditions that applicants assume are disqualifying are actually manageable with proper documentation and treatment compliance.
Not Sure If You Qualify?
Many applicants who are worried about disqualification are still eligible. Get matched with a Texas CDL school — admissions teams deal with these situations regularly and can help you understand your options before you commit to anything.

Criminal History and CDL Eligibility
Not all criminal history affects CDL license eligibility. Federal law specifies a narrow set of offenses that can disqualify you from holding a CDL. For most other criminal history, the question is less about whether you can get licensed and more about whether specific employers will hire you.
✕ May Affect CDL License Eligibility
- Using a commercial vehicle in the commission of a felony involving controlled substances
- Felony resulting in death where a commercial vehicle was involved (e.g., vehicular manslaughter in a CMV)
- Leaving the scene of an accident involving a commercial vehicle
- Certain offenses listed under the federal human trafficking statute
⚠ May Still Obtain a CDL License
- Past drug or alcohol offense (non-vehicular) — depends on time elapsed and specific charge
- Non-violent felony conviction — many do not trigger federal CDL license disqualification
- Misdemeanor offenses — generally not a CDL license disqualifier under FMCSA rules
- Expunged records — varies by state law; outcomes are not guaranteed
⚠ Hazmat Endorsement — Stricter Rules Apply
Even if you qualify for a base CDL, the Hazmat endorsement requires a separate TSA background check and fingerprinting — independent of the CDL licensing process. Certain convictions that do not block your CDL license may still prevent you from obtaining a Hazmat endorsement. If oilfield, tanker, or chemical hauling routes are your goal, ask about this before choosing a training path. See the full CDL endorsements guide.
If hazmat or tanker routes interest you, see our CDL endorsements explained guide — endorsements can significantly affect truck driver salary in Texas.
License eligibility vs employer hiring are separate. Texas DPS may issue you a CDL even with a criminal history that doesn't meet a federal disqualification. Whether a specific carrier then hires you depends on their background check policies — which vary significantly by company and route type.
Other Things That Can Affect CDL Eligibility
Minimum Age
You must be at least 18 to hold a Texas CDL for intrastate (in-state) driving. You must be at least 21 for interstate (crossing state lines) commercial driving. Most OTR trucking jobs require age 21 or older.
Driving Record
Excessive moving violations, license suspensions, or a pattern of reckless driving can affect your ability to obtain or retain a CDL, even if each individual incident wouldn't disqualify you on its own.
Active License Status
You cannot obtain a CDL if your regular driver's license is currently suspended or revoked. Outstanding license issues must be resolved before applying for a CDL in Texas.
Failed Drug / Alcohol Test
CDL drivers are subject to DOT drug and alcohol testing. A failed pre-employment test enters your record in the FMCSA Drug and Alcohol Clearinghouse, which employers are required to check before hiring CDL drivers.
Disqualified, Delayed, or Still Eligible?
Most applicants with concerns fall into one of three categories. Understanding which one applies to you changes what to do next.
✕ Currently Disqualified
Your situation triggers an active federal or state disqualification right now. Examples: DUI within the past year, current license suspension, second DUI lifetime bar, or a specific listed felony offense.
Next step: Understand your timeline and when the disqualification period ends, if applicable.
⏱ Delayed — Not Permanently Out
Your disqualification period has ended, your condition is manageable, or your record doesn't trigger a federal licensing bar. You may be eligible to apply now or soon.
Next step: Get a DOT physical or speak with a CDL school admissions team to confirm your current standing.
✓ Still Eligible — Apply Now
Many applicants who worried they were disqualified aren't. A past incident, medical condition, or criminal record does not automatically mean you can't hold a CDL. Many licensed drivers have similar histories.
Next step: Get matched with a school and confirm your specific situation before writing yourself off.
What to Do If You're Not Sure
Don't assume the worst. Here are four concrete steps to get clarity on your situation before ruling yourself out.
-
1Check your Texas driver's license status. Visit the Texas DPS website to confirm your license is valid and unsuspended. No CDL application can proceed with an active suspension.
-
2Review your DUI or criminal timeline. If a DUI or relevant conviction is on your record, calculate how much time has passed since the conviction date. The 1-year disqualification period runs from conviction, not arrest. Two or more DUI convictions is a different situation — confirm the specifics.
-
3Schedule a DOT physical if a medical condition is the concern. A certified DOT medical examiner can tell you whether your specific condition meets commercial driving standards. This is far more reliable than guessing. Find a certified examiner through the FMCSA National Registry of Certified Medical Examiners.
-
4Talk to a CDL school admissions team. CDL school admissions teams deal with applicants who have DUIs, criminal records, and medical concerns regularly. They can often help you understand whether your situation affects licensing, hiring, or both — before you commit to anything. Get matched with a Texas CDL school →
