How to scan your CDL, medical card and other onboarding documents so they're accepted the first time

Signing on with a new carrier, leasing on as an owner-operator, or renewing your paperwork with an existing one means sending copies of the same handful of documents: your commercial driver's license, your DOT medical examiner's certificate, and often a Social Security card, a TWIC card or a passport. The safety or HR person reviewing them needs to read every number and date. When they can't, the packet comes back and your start date slides.

ID cards are harder to scan than a sheet of paper. They're small, glossy, often laminated, and full of fine print and holograms that reflect light. A few adjustments make the difference.

What's usually in a driver onboarding packet

Every company's list is different, but these come up most often:

• CDL, front and back. The back often shows endorsements, restrictions and the card's audit or document number.
• DOT medical examiner's certificate (the "med card"). Reviewers check the examiner's name and registry number, the expiration date, and any restrictions such as corrective lenses.
• Social Security card or other proof required for employment eligibility and payroll.
• TWIC card, if you'll be going into ports or other secure facilities.
• Previous employment and accident history forms.
• Signed consent forms for background checks, motor vehicle records and drug and alcohol testing.

Owner-operators leasing on often add their truck registration, insurance certificates, the lease agreement, and a W-9.

How to scan an ID card well

Set up the shot

1. Use a dark, plain background. A dark table or a sheet of dark paper gives automatic edge detection a clear outline to find. A white card on a white counter is hard for any scanner to crop.
2. Lay the card flat. If it curls, hold the edges down with two fingers outside the card itself, or put it under a clean sheet of glass from a picture frame.
3. Avoid direct overhead light. Glare from a ceiling light or flash across the lamination can wipe out a date or a license number. Diffuse daylight from a window, coming from the side, works best. Turn the flash off.
4. Hold the phone parallel to the card, close enough that the card fills a good part of the frame but not so close that the camera can't focus. Most phones focus better a few inches away than right up against the card.

Capture front and back

Scan the front and the back as separate pages of the same document. The back of a CDL often carries information the reviewer specifically needs.

Check the scan before sending

Zoom in on:

• The license or certificate number
• Date of birth and expiration date
• Endorsements and restrictions
• The examiner's name and registry number on a medical card
• Your signature

If any of those are washed out by glare, tilt the card slightly and rescan. Glare moves when the angle changes.

Choose the right filter

• Color for ID cards. Reviewers often look at the photo, the background pattern and the colored security features to judge whether the card is genuine. A black-and-white copy of a license is more likely to be questioned.
• Black and white for full-page typed forms like consent forms and applications. They're smaller and easier to read.
• Grayscale for faint documents, like a faded medical certificate copy.

Putting the packet together

Rather than sending eight separate photos, combine them into one PDF in the order the company asked for — or, if they didn't say, a sensible order:

1. Application and signed consent forms
2. CDL, front then back
3. Medical certificate
4. Other IDs (TWIC, Social Security card, passport)
5. Anything else they requested

Name the file clearly: Lastname_Firstname_Onboarding_2026-10.pdf. If the company uses an upload portal with separate slots for each document, upload each one separately instead, named by what it is, such as Lastname_CDL.pdf and Lastname_MedCard.pdf.

If you need to fill in or sign any of the forms, do that in a PDF editor before combining, so the final file has everything in one place.

Handle these documents carefully

Onboarding packets contain the information identity thieves look for: your full name, date of birth, license number and Social Security number in one file. A few habits reduce the risk:

• Send only what's requested. If the company asked for your CDL and med card, don't also include your Social Security card "just in case."
• Prefer the company's secure upload portal over email, if they have one.
• Verify who you're sending to. Recruiting scams exist. Confirm the recruiter's email domain matches the company and that the company is real before sending ID documents.
• Don't post them in group chats. Even a private driver group isn't the right place for your Social Security card.
• Delete extra copies from your phone's camera roll once the packet is sent and saved somewhere secure, such as a password-protected account.

Example

A driver applying with a new carrier is asked for a CDL (front and back), med card and signed MVR consent form, uploaded as one PDF. The driver lays the CDL on a dark notebook near a window, scans the front and back in color, scans the med card in grayscale because it's a lightly printed copy, then opens the emailed consent form, signs it and adds the date. All four pages are combined into Ramirez_Luis_Onboarding.pdf — about 1.2 MB — and uploaded to the carrier's portal. The safety manager can read the expiration date on the med card without asking for a new copy.

Common mistakes

• Glare across the license number. The most common reason ID scans are rejected. Move the light, not just the phone.
• Only the front of the CDL. Endorsements and restrictions are often on the back.
• An expired medical card. Check the date before you send it; reviewers will.
• Cropping too tightly. Leave the card's rounded corners visible so the reviewer can see it's a whole card.
• Huge files. A packet of raw phone photos can exceed portal limits. Scanned and cleaned pages are much smaller.
• Mismatched names. If your name differs between documents (a maiden name on one, for example), mention it upfront.

FAQ

Is a phone scan acceptable for a CDL copy?

Many carriers accept clear phone scans for their records. Some may also ask to see the physical card in person during orientation. Follow the company's instructions.

Should I send my med card in color or black and white?

Grayscale or color usually reads best for medical certificates, especially copies, because faint print survives better than with strict black-and-white.

Can I cover part of my Social Security number?

Only if the company tells you that's acceptable. For employment paperwork, they usually need the full number. For other purposes — like proving identity to a landlord — it's reasonable to ask whether a partial number is enough.

How do I keep copies for my own records?

Save the final PDF in a secure place you control, such as your document storage account, so you can resend it later without rescanning. Keep it updated when your med card renews.

What if my card is damaged or cracked?

Scan it as clearly as possible and mention the damage. If key details are unreadable, you may need a replacement card before the company can accept it.
