What to do immediately after a truck accident

Reviewed by the Learn Injury Law editorial team

After a truck accident, call 911, get medical evaluation within 24 hours, and contact a truck accident attorney within 24–48 hours. Evidence like black box data and driver logs is permanently deleted unless a preservation letter is issued immediately. Commercial trucks carry $1 million or more in liability coverage, but trucking companies have legal teams working to minimize payouts from the moment the accident happens.

The First Decision: Safety and Medical Attention

Get out of traffic immediately and call 911 — truck accidents produce more severe injuries than car collisions because of the weight differential, and adrenaline masks concussions, broken ribs, spinal injuries, and internal bleeding that surface hours later.

Get yourself out of traffic first, just as you would with any accident. If your vehicle is drivable and you're in a roadway, move it. If you're hurt or trapped, stay put and call 911 immediately. The paramedics will document injuries on scene, and that official record matters in a truck accident case just as it does in any collision.

Truck accidents produce more serious injuries than typical car collisions because of the weight differential and impact force. Go to the emergency room or an urgent care facility tonight or tomorrow morning, even if you feel okay. Tell them about the accident, how it happened, and exactly where you felt the impact. This medical evaluation creates a baseline that protects your health and your claim.

If there are other people in your vehicle, check on them. If anyone reports pain, difficulty moving, or any uncertainty about their condition, call 911. The paramedics will evaluate everyone, and the documentation of injuries matters for the legal process ahead.

Call 911 and Get Everything Documented

A police report in a truck accident is critical evidence — ask the officer whether they spoke with the truck driver about logbooks, hours of service, and whether the truck has a dash camera or black box.

Call 911 if anyone is injured or if there's significant damage — which, after a truck accident, there almost certainly is. Tell them you're involved in a collision with a commercial truck, your location, and whether anyone is injured.

When police arrive, give them a straightforward account of what happened. Stick to facts: what you were doing, what direction you were traveling, what you observed the truck doing. Don't speculate about why the truck driver did something or whether they were distracted or tired. Just describe what happened. "I was in the right lane heading west on Route 9 when a semi-truck came from behind in the right lane and struck my vehicle."

Ask for the police report number before the officer leaves, and ask how you can obtain the full report. That report becomes crucial evidence.

Truck accidents require more information than a typical car accident report provides. Ask the officer whether they spoke with the truck driver, whether the driver provided a logbook or mentioned their hours of service, whether the trucking company name and truck number are documented in the report, and whether the officer noted a dash camera or black box. These pieces of evidence are time-sensitive.

If you're seriously injured and unable to advocate for yourself right now, ask a family member or a trusted person to make that call and ask those questions. This matters.

Document the Scene Before It Changes

Photograph both vehicles from multiple angles, the damage, the road layout, skid marks, and any identifying information on the truck — company name, truck number, license plate.

Get the scene itself — traffic signals, sight lines, the position of the truck relative to your car. If there are witnesses, get their names and contact information. Ask what they saw. Their account of a truck that seemed to be drifting, or accelerating suddenly, or failing to brake becomes critical evidence later.

Don't have a long conversation with the truck driver about the accident or who was at fault. Be polite and brief. Get their name, company name, phone number, and commercial driver's license number. Get their insurance information — not just a company name, but the policy number. Trucking companies carry commercial liability insurance, and sometimes multiple insurance policies depending on the cargo and other factors. You need to know exactly which company is insuring this particular accident.

The Commercial Insurance Process Is Different

Trucking companies carry commercial liability insurance with specialized investigation teams working to minimize payouts — your next call should be to your own insurance company, but do not give a recorded statement without talking to an attorney first.

When your insurance company investigates, they'll be dealing with a trucking company's insurance. That insurance company has its own investigation team, and they're investigating on behalf of the trucking company and the driver. Their job is to minimize what the company pays, which means they'll look for ways to shift liability — to the truck driver's fatigue, to your driving, to road conditions, anything but the company's negligence or maintenance failures.

Your own insurance company will handle your claim, but if your injuries are significant or if liability is disputed, you need an attorney who understands commercial trucking liability. This is different from a car accident — the stakes and the complexity are higher.

Tell your insurance company you were hit by a commercial truck. Have the truck company's information ready. Have the police report number. Be straightforward when they ask what happened, but don't provide a recorded statement without talking to an attorney first. In a commercial trucking case, recorded statements can be used against you, and the process is more adversarial than it is with regular car accident cases.

The Evidence That Disappears If You Don't Act

Black box data, driver logs, and maintenance records are permanently deleted unless you issue a preservation letter within days — contact a truck accident attorney within 24–48 hours to protect this evidence.

This is the part that's urgent and different from a regular car accident. Commercial trucks have electronic data devices — black boxes or event data recorders that capture information about the truck's speed, braking, acceleration, and sometimes GPS data. That data is preserved for a limited time. Some devices overwrite data after a period of weeks or months.

Trucks have driver logs. Federal regulations require truck drivers to maintain detailed logs of their hours of service — how many hours they've been driving, how many hours they've rested. These logs show whether the driver was complying with federal rules about rest breaks and maximum driving hours. A fatigued driver who violated hour-of-service regulations is evidence of negligence.

Maintenance records are evidence. If the truck had braking problems, tire problems, or other maintenance issues, that's evidence. Records of previous accidents involving that truck are evidence. The trucking company's safety record is evidence. All of this can be subpoenaed and discovered in a legal case, but only if you have an attorney pushing for it early.

If you don't hire an attorney or don't have someone documenting that evidence immediately, the trucking company can discard driver logs after a certain period, can argue that black box data was overwritten in the normal course of operations, can claim that maintenance records were lost. A preservation letter — a formal request to keep all relevant evidence related to the accident — is a standard step that puts the company on notice that they cannot destroy evidence without legal consequence. Your attorney needs to issue this within days of the accident.

Medical Attention and Documentation

Whether you felt injured at the scene or not, get a full medical evaluation within 24 hours — truck accidents result in more serious injuries than car accidents, and medical documentation directly affects what your case is worth.

See your primary care doctor, or go to an urgent care facility if that's faster. Tell the doctor exactly what happened and where you felt impact. Be specific about pain, even if it's minor. Be honest about any symptoms that appeared only after you'd calmed down — headaches, dizziness, neck pain, soreness that showed up hours later.

Keep every medical record, every bill, every receipt. Imaging studies, physical therapy, follow-up appointments, prescriptions — collect it all. If you're having pain or difficulty weeks after the accident, keep getting medical attention. Don't tough it out hoping it will go away. A documented history of medical treatment shows the severity and duration of your injuries.

Deciding on an Attorney

Not every car accident requires an attorney, but most truck accidents do — the evidence is time-sensitive, the insurance process is adversarial, and federal motor carrier regulations create complexity that requires specialized knowledge.

If you were injured — broken bones, head injuries, significant pain, any injury requiring ongoing treatment — talk to an attorney who handles truck accident cases. If the accident was severe enough that your vehicle was totaled, that's another reason. If the police report is unclear about what happened, if the truck driver is claiming you caused the accident, if the trucking company is being uncooperative — any of these is a reason to call.

Most truck accident lawyers work on contingency, meaning they don't get paid unless they recover money for you. You won't be paying them upfront. Call an attorney who specializes in truck accidents or commercial vehicle liability. They'll understand the federal regulations, the insurance dynamics, and the evidence preservation issues that make these cases different.

What Comes Next

Right now, you're dealing with the immediate aftermath. You're hurt, shaken, and trying to figure out how to move forward. You've done the right things — you got safe, you got medical attention, you're documenting what happened. That's what matters right now.

The system will move forward from here. It won't move at your pace; these cases take time. But you don't have to have it all figured out today. You just have to take the next step, which is getting proper legal advice and making sure the evidence is preserved. Everything else builds from there.

You're going to be okay. Truck accidents are serious, but people recover from them. And the legal system, when it works the way it's supposed to, is designed to make sure you're compensated for what you've been through.

FAQ

How quickly should I contact a truck accident attorney?

Within 24–48 hours if possible. Black box data and driver logs are time-sensitive — the trucking company can discard or overwrite this information if you don't issue a preservation letter immediately. The earlier an attorney gets involved, the more evidence they can protect.

What is a preservation letter?

A formal written request to the trucking company and driver instructing them to retain all evidence related to the accident, including driver logs, maintenance records, dispatch records, and electronic data from the truck. It prevents the company from claiming evidence was lost in the normal course of operations.

Should I give a recorded statement to the insurance company?

Not without consulting an attorney first. Recorded statements in commercial trucking cases are used against you and the process is more adversarial than in regular car accidents. It's reasonable to say you'd like to understand the process before giving a recorded statement.

What makes truck accident cases different from regular car accidents?

Federal regulations apply to truck drivers and companies, evidence like black boxes and driver logs is time-sensitive, multiple insurance policies cover the accident, and trucking companies have sophisticated legal teams working to minimize payouts. The injuries are also typically more severe due to the weight and speed differential.

Can I settle my truck accident claim quickly?

Don't accept any settlement without consulting an attorney about what your case is actually worth. Trucking companies and their insurance have sophisticated teams working to minimize payouts. An attorney evaluates settlement offers and ensures you're compensated fairly for your injuries, lost wages, and pain and suffering.
