Do truck drivers need a TWIC card to haul from a port?
Yes, in most cases. A TWIC card from TSA is required for unescorted access to secure areas of ports and other maritime facilities, which is where container pickups and drop-offs happen. Drayage carriers also usually need an intermodal interchange agreement, terminal registration and the right insurance before they can pull a container.
The TWIC card (Transportation Worker Identification Credential) is the federal ID that lets you into secure areas of ports and maritime terminals without an escort. If you want to haul containers in and out of a port, the TWIC is step one, but it is not the only thing standing between you and your first drayage load.
What a TWIC card is
TWIC is run by the Transportation Security Administration together with the US Coast Guard. It is a tamper-resistant card tied to a background check, and it is required for unescorted access to secure areas of facilities and vessels regulated under the Maritime Transportation Security Act. That includes container terminals at seaports and many river and inland port facilities.
Key facts:
- The card is generally valid for five years.
- It is tied to you, not to a company. It moves with you if you change carriers.
- Holding a TWIC does not by itself grant entry. Each terminal still decides who comes in, and usually requires a business reason, such as a booked container move.
Who can get one
TSA runs a security threat assessment that checks criminal history, immigration status and certain other records. US citizens and lawful permanent residents are eligible, along with some other immigration categories. Certain serious offenses disqualify applicants permanently or for a set period, and TSA has a waiver and appeal process. Review TSA's current list of disqualifying offenses before you apply.
How to apply for a TWIC, step by step
- Pre-enroll online through TSA's official enrollment program. Pre-enrolling saves time at the center.
- Book an appointment at an enrollment center. Many are in port cities, and some are inside other TSA enrollment locations.
- Bring identity documents. Usually a passport, or a combination such as a driver's license plus a birth certificate. Check the accepted list before you go.
- Give fingerprints and pay the fee. The fee is set by TSA; check the current amount.
- Wait for the background check. Many applicants are approved within a few weeks; some take longer.
- Pick up or receive the card, depending on the option you chose, and activate it if required.
If you lose the card, report it and order a replacement; there is a separate replacement fee.
Beyond TWIC: what else drayage requires
The TWIC gets you through the gate. Pulling a container also usually requires:
| Requirement | Why it matters |
|---|---|
| Intermodal interchange agreement | Steamship lines and equipment providers require carriers to sign a standard interchange agreement before you can take their containers and chassis. |
| Terminal or port registration | Many ports keep a registry of trucks and carriers allowed to enter. Some tie it to clean-truck or engine-age rules. |
| Insurance | Interchange agreements usually require specific coverages, often including trailer interchange coverage. Talk to your insurance agent. |
| SCAC code | Many terminals and steamship lines use your Standard Carrier Alpha Code to identify your company. |
| Appointment system access | Most busy terminals require a booked appointment for each pickup or return. |
| Day cab or sleeper | Either works. Many drayage operators run day cabs because they are lighter and easier to maneuver. |
Requirements are set by each port, terminal and equipment provider, and they change. Ask the terminals you plan to serve exactly what they need.
The chassis check you should never skip
In drayage, you often hook to a chassis you have never seen before. You are responsible for its roadability once you leave the gate. Before you pull out:
- Check tires for tread depth, cuts and proper inflation.
- Test all lights, including brake and turn signals.
- Look at brakes, slack adjusters and air lines for leaks.
- Confirm twist locks are engaged on every corner.
- Check the mudflaps, landing gear and the inspection sticker.
- Note container seal number and compare it to your paperwork.
If something fails, take it to the terminal's repair area before leaving. A defect found at a roadside inspection is your violation, not the chassis owner's. See our pre-trip inspection checklist.
Watch the weight
Containers are loaded by shippers you never meet, and some leave the port heavy. Federal limits generally cap gross weight at 80,000 lbs on the Interstate system, with axle limits on top of that. Ways to protect yourself:
- Check the declared weight on the paperwork before you accept the move.
- Scale the load at the first certified scale if you have any doubt.
- Know your tractor and chassis tare weight so you can do quick math.
Hypothetical example: tractor 17,500 lbs + chassis 6,500 lbs = 24,000 lbs empty. That leaves about 56,000 lbs for container plus cargo before you hit 80,000 lbs. A 40-foot container itself can weigh around 8,000 lbs, so cargo much above 48,000 lbs is a red flag. Some states allow overweight container permits on certain routes near ports; see oversize and overweight permits.
Making drayage pay
Drayage is paid per move, not per mile, so time is the real cost. Things that eat into it:
- Terminal wait times. Long lines can turn a 40-mile move into a full day.
- Detention and chassis fees. Know who pays if the receiver holds your chassis.
- Per diem and storage charges on late container returns. Get clear on who is responsible.
- Dry runs. If the container is not available when you arrive, ask for dry run pay.
Track your average hours per move and compare it to the rate. The detention pay calculator and cost per mile calculator can help you see your true hourly earnings.
Quick drayage startup checklist
- TWIC card issued and activated
- USDOT and MC active, SCAC code obtained
- Interchange agreement signed
- Port or terminal registration complete
- Insurance meeting interchange requirements
- Appointment system logins set up
- Pre-trip routine for unfamiliar chassis
Fees, eligibility rules and port programs change. Confirm current requirements with TSA, the US Coast Guard, and each port and terminal you plan to serve.

Frequently asked questions
How long is a TWIC card valid?
A TWIC card is generally valid for five years. Start the renewal a couple of months early because enrollment, background check and card production all take time.
Can I get into a port without a TWIC card?
Some facilities allow escorted access, but escorts are rarely practical for truck drivers doing regular pickups. For steady drayage work, plan on getting the card.
Does a TWIC card help with the hazmat endorsement?
TSA has offered a reduced hazmat threat assessment fee for applicants who hold a valid TWIC, since the background checks overlap. Ask TSA about current options when you apply.
Is drayage good for a new owner-operator?
It can be, because runs are short and you sleep at home. But pay per load, wait times at terminals and equipment requirements vary a lot by port, so run the numbers for your local market first.
