If your child is autistic, you may have heard that Florida can mark a license, an ID card or a car's registration so officers and first responders know to slow down and communicate differently. There are two separate tools, they work in different ways, and they show different amounts of information. This guide compares them side by side, explains exactly what the statutes and the FLHSMV form require, and gives you a checklist for deciding what fits your family. Florida's newer blue envelope and blue card, starting in 2027, are covered in our blue envelope guide.
What is the "D" designation on a Florida driver license?
Section 322.14(1)(f)1., Florida Statutes, says: "Upon request by a person who has a developmental disability, or by a parent or legal guardian of a child or ward who has a developmental disability, the capital letter 'D' shall be exhibited on the driver license of a person who has a developmental disability, as defined in s. 393.063, if the person, or his or her parent or legal guardian, presents sufficient proof that the person has been diagnosed with a developmental disability by a physician licensed under chapter 458 or chapter 459 as determined by the department."
In plain terms:
- It is voluntary and must be requested.
- A parent or legal guardian can request it for a child or ward.
- Proof must come from a physician licensed under chapter 458 (MD) or chapter 459 (DO).
- Until the next renewal, the D can be added or removed by surrendering the current license with the required proof. If you are not doing any other transaction, the replacement license "may be issued with the capital letter 'D' added or removed without payment of the fee" for a replacement license (s. 322.14(1)(f)2.).
This rule was added by chapter 2020-178, Laws of Florida.
What is the "D" designation on a Florida ID card?
Many autistic children and teens will not drive for years, or ever. A Florida identification card can carry the same letter. Under s. 322.051(8)(e), on request by the person or "by a parent or guardian of a child or ward who has a developmental disability," FLHSMV "shall issue an identification card exhibiting a capital 'D'" if the applicant submits:
- "Payment of an additional $1 fee"; and
- "Proof acceptable to the department of a diagnosis by a licensed physician of a developmental disability as defined in s. 393.063."
The $1 goes to the Agency for Persons with Disabilities trust fund, and a replacement card that adds the designation "may be issued without payment of the fee" for a replacement card. The extra $1 is on top of the regular ID card fee, which FLHSMV sets under s. 322.21. FLHSMV's designation fee page lists the developmentally disabled designation as "Issuance Fees + $1."
Who can get a Florida ID card at all? Under s. 322.051(1), any person "5 years of age or older," or a person with a disability of any age who applies for a disabled parking permit. An ID issued to a child aged 5 to 14 expires on the fourth birthday after it is issued, so plan to update the photo and the card as your child grows.
Does autism qualify as a "developmental disability"?
Yes. Section 393.063 defines a developmental disability as "a disorder or syndrome that is attributable to intellectual disability, cerebral palsy, autism, spina bifida, Down syndrome, Phelan-McDermid syndrome, Prader-Willi syndrome, or Tatton-Brown-Rahman syndrome; that manifests before the age of 18; and that constitutes a substantial handicap that can reasonably be expected to continue indefinitely."
ADHD alone is not on that list, so a child with ADHD but no qualifying condition would not meet the D designation definition. ADHD is, however, listed for the SAFE flag below.
What is the SAFE designation on a vehicle registration?
Section 320.02(15) requires Florida's vehicle registration application to let an applicant "voluntarily indicate that the applicant has been diagnosed with, or is the parent or legal guardian of a child or ward who has been diagnosed with," certain conditions "by a physician licensed under chapter 458 or chapter 459." The list is: autism; attention deficit hyperactivity disorder; Down syndrome; Alzheimer's disease; traumatic brain injury; posttraumatic stress disorder; diabetes; an autoimmune disorder; deafness; blindness; and "any other mentally or physically limiting disorder."
If you indicate one of these, FLHSMV "must include the designation 'SAFE' in the motor vehicle record." The statute adds that the department "may not include in the motor vehicle record personal identifying information of, or any diagnosis of, a person for whom a diagnosis is indicated," and must let the owner or co-owner "include or remove the 'SAFE' designation under this subsection at any time."
FLHSMV's application form explains the purpose: the SAFE designation "will be used so that communication awareness can be established when interacting with law enforcement or first responders in an emergency or crisis situation."
How do the D designation and the SAFE flag compare?
| "D" on driver license | "D" on ID card | SAFE vehicle flag | |
|---|---|---|---|
| Statute | s. 322.14(1)(f) | s. 322.051(8)(e) | s. 320.02(15) |
| Attached to | The person's license | The person's ID card | A vehicle's registration record |
| Who qualifies | Developmental disability under s. 393.063 (includes autism) | Same | Autism, ADHD, Down syndrome and other listed conditions |
| Who can request | The person, or a parent or legal guardian | The person, or a parent or guardian | A registration applicant who has the condition or is the parent or legal guardian of a child or ward who does |
| Proof | Physician licensed under ch. 458 or 459 | Licensed physician (the FLHSMV form asks for a ch. 458 or 459 license number) | Physician licensed under ch. 458 or 459 |
| Cost | No replacement fee when only adding or removing the D | Issuance fees plus $1 | The statute sets no separate fee |
| Who sees it | Anyone shown the license | Anyone shown the ID | Anyone who checks the vehicle record, such as an officer at a traffic stop |
| Shows diagnosis? | Shows a developmental disability, not which one | Same | No; the record shows only "SAFE" |
| Can be removed? | Yes | Yes (by replacement) | Yes, at any time |
How do I apply?
FLHSMV uses one form for both tools: HSMV 72120, Application for Driver License Developmental Disability Designation and/or Motor Vehicle Registration SAFE Designation (Rev. 05/25 at the time of writing). The form says to submit it "to your local tax collector office or driver license service center."
- Section 1: the applicant, parent or legal guardian fills in personal details and signs.
- Section 2: tick whether the D goes on a driver license or an identification card.
- Section 3: to add or remove SAFE, list each vehicle's plate number, VIN, year and make.
- Section 4: a physician licensed under chapter 458 or 459 completes a statement of certification, giving their license number and attesting to the diagnosis.
Watch for this: the physician statement must be signed by an MD or DO. If your child's autism diagnosis came from a psychologist, ask your child's pediatrician or another treating physician whether they can complete Section 4 based on the records. A behavior analyst cannot sign it.
FLHSMV began issuing a newly designed license and ID on September 30, 2026. FLHSMV says existing valid cards stay in circulation, and its FAQ says that if you wish to add one of the new designations, you may visit a local service center to get the newly designed credential "with certain fees waived." Fees and procedures change, so check FLHSMV's designation fee page before you go.
What are the privacy trade-offs?
Both tools are optional, and both can be undone. Things to weigh:
- The D is visible. Anyone who handles the card sees it, not only police: a store clerk, a bank, an employer, a landlord. For some teens and adults, that is a reason to prefer the SAFE flag or the blue card, which they control.
- The SAFE flag is quieter. It does not show a diagnosis, but it is attached to the vehicle, so it appears whenever that car is checked, no matter who is driving.
- Your child's voice matters. As autistic children grow into teens and adults, many want a say in who knows about their diagnosis. The D can be removed later.
- Neither tool guarantees a particular response. Officers' expanded autism training must be completed by July 1, 2030 (s. 943.1727), so training levels vary until then.
A decision checklist for your family
- Does your child have a Florida ID or license, or do you plan to get one? If not, the SAFE flag may be the only option for now.
- Is your child usually a passenger in one or two family cars? The SAFE flag covers those cars, not your child in someone else's car.
- Does your child go out without you, or wander? A visible ID with a D, plus an ID bracelet, may help a stranger or officer more quickly.
- Is your teen comfortable with a visible marker? If not, consider the SAFE flag or wait for the blue card in 2027.
- Do you have a physician (MD or DO) who can sign Section 4 of form HSMV 72120?
- Have you added your child to your wandering safety plan and practiced what to do if stopped? See autism and police in Florida.
