Texas is in the middle of a real, dated transition away from paper medical certificates entirely — and the state's self-certification system uses its own specific form numbers most guides never actually name. With nearly 775,000 valid CDL holders in Texas, this is one of the highest-stakes compliance processes on the entire CDL journey. Here's exactly how it works.
The DOT physical is a federal exam required for most CDL holders, performed only by an examiner listed on the FMCSA National Registry of Certified Medical Examiners — not just any physician.
| Test Area | Minimum Standard |
|---|---|
| Vision | 20/40 in each eye, corrective lenses permitted |
| Hearing | Perceive a forced whisper at 5 feet in the better ear |
| Blood pressure | Below 140/90 for a full 2-year certificate |
| Urinalysis | Checks kidney function and glucose — not a drug test |
Every Texas CDL holder and CLP applicant completes a Self-Certification Affidavit (Form CDL-7), plus one category-specific form that determines whether a medical certificate is required at all.
| Category | Form | Medical Cert Required? |
|---|---|---|
| Non-Excepted Interstate Commerce | CDL-4 | Yes — most CDL holders fall here |
| Excepted Interstate Commerce | CDL-10 | No — but must meet Texas medical standards; restricted to the certified excepted activity |
| Non-Excepted Intrastate Commerce | CDL-5, Part B | Yes, with possible state waiver for certain conditions (Form CDL-37) |
| Excepted Intrastate Commerce | CDL-5, Parts A or C | No — covers pre-1989 drivers or oil/water well servicing and mobile crane operations specifically |
Texas has been transitioning to electronic medical certification for over a year. Texas began accepting certification electronically from the FMCSA National Registry on March 23, 2025. Effective April 10, 2026, Texas DPS will no longer accept paper medical certificates at all.
You must submit a copy of your new DOT medical certificate to Texas DPS within 15 days of the medical certificate's issuance date to prevent your CDL from being downgraded. Allow up to 10 business days after submission for your record to update in the License Eligibility system.
| Milestone | Timeframe |
|---|---|
| Submit new certificate to DPS | Within 15 days of issuance |
| DPS processes and updates record | Up to 10 business days |
| Courtesy expiration notice sent | ~60 days before current certificate expires |
