Use a calm post-crash procedure to protect people, secure the scene, notify the right contacts, preserve facts, understand FMCSA recordability, and remain available for required testing.
A crash plan must work under stress
The minutes after a commercial-vehicle crash are noisy, dangerous, and legally important. A useful plan is simple enough to follow when adrenaline is high: stop, assess hazards, call for emergency help, protect people without creating another collision, notify the carrier, preserve facts, and follow testing instructions. Carrier policy, state law, emergency responders, hazardous-material rules, and the facts of the event can add duties, so drivers should receive written procedures before dispatch.
Stop and control the immediate hazard
Bring the vehicle to a controlled stop as close to the scene as safety and law permit. Set the parking brake, place the transmission in the appropriate position, shut down equipment when conditions require it, and scan for traffic, fire, smoke, fuel or cargo release, electrical hazards, unstable vehicles, and injured people. Do not move into live lanes or stand between vehicles. If remaining in the vehicle creates greater danger, exit only by the safest available route.
Call 911 and give a precise location
Report the road, direction of travel, nearest mile marker or exit, cross street, visible injuries, number and type of vehicles, fire or spill, blocked lanes, and any placarded cargo. Use the route map, GPS coordinates, bills, or roadside landmarks to confirm location, but do not delay the call while searching for perfect information. Follow the dispatcher's instructions and update responders when the situation changes.
Prioritize medical care
Check yourself before assisting others; shock, head injury, and internal injury may not be obvious. Give only aid you are trained and able to provide without exposing yourself to traffic, fire, hazardous materials, or unstable equipment. Do not move an injured person unless an immediate threat requires it. Federal post-accident testing rules do not require delaying necessary medical attention or prevent a driver from leaving to obtain emergency help or care.
Protect the stopped vehicle and scene
Activate hazard warning flashers immediately when a stopped CMV creates the conditions covered by 49 CFR 392.22. Place warning devices within the time and pattern required by the regulation when it is safe to do so, accounting for curves, hills, divided roads, and obstructions. Never walk into traffic merely to place a triangle. Police, fire, roadway workers, weather, cargo, or site conditions may require a different safe response.
Treat fire, fuel and hazardous cargo separately
If there is smoke, fire, a fuel leak, a damaged battery system, or a hazardous-material release, move people away and upwind when possible, call emergency services, and identify placards and shipping papers from a safe location. Do not touch, smell, taste, contain, or clean an unknown substance unless trained, equipped, and authorized. Keep ignition sources away and provide responders with the carrier's emergency contact and required shipping information.
Notify the carrier through the approved channel
After emergency notification, contact dispatch, safety, or the carrier's crash-response number. Give the unit numbers, location, injuries as known, vehicle and cargo condition, law-enforcement agency, tow needs, and whether traffic is blocked. Ask who will coordinate towing, cargo recovery, insurance, testing, and customer communication. If the phone or ELD fails, use the backup method in the carrier's plan and record when each notification was attempted.
Exchange facts without debating fault
Provide identification, license, registration, insurance, and carrier information as required. Record the other driver's name, contact information, vehicle, plate, insurer, and policy details when permitted and safe. Be truthful and cooperative with law enforcement, but do not speculate about speed, distance, mechanical cause, injury severity, or fault. Avoid arguments, apologies interpreted as admissions, social-media posts, and promises about payment.
Preserve evidence safely
From a protected location, photograph the vehicle positions, roadway, lane markings, signs, signals, skid or debris areas, cargo, damage, plates, weather, lighting, and wide scene views. Note the time, direction of travel, route, approximate location, witnesses, responding agencies, report number, tow company, and medical transport. Do not enter a closed area, interfere with responders, alter required records, or photograph injured people unnecessarily. Follow company privacy and evidence rules.
Protect electronic and paper records
Preserve the ELD record, driver vehicle inspection reports, bills of lading, dispatch messages, fuel and toll receipts, dash-camera information, maintenance reports, and photographs according to carrier instructions. Do not edit, annotate, delete, overwrite, or recreate electronic data outside an authorized correction process. A clean chain of custody helps the carrier answer investigators, insurers, and enforcement without guessing later.
Know the FMCSA accident definition
For Part 390 recordkeeping, an accident generally means a CMV occurrence on a highway in interstate or intrastate commerce that results in a fatality, bodily injury requiring immediate medical treatment away from the scene, or disabling damage requiring a vehicle to be transported away by tow or another motor vehicle. Loading- or unloading-only events and boarding or alighting from a stationary vehicle are excluded from that definition. State reporting and carrier policies may cover additional events.
Disabling damage has a specific meaning
Section 390.5 defines disabling damage as damage that prevents a vehicle from leaving the scene in its usual manner in daylight after simple repairs, including a vehicle that could move but would be further damaged if driven. Tire disablement alone, unavailable spare tires, and certain lamp, signal, horn, or wiper damage are excluded from that federal definition. This definition is for regulatory classification; a vehicle can still be unsafe or illegal to drive even when an event is not FMCSA-recordable.
The carrier maintains the accident register
Under 49 CFR 390.15, covered motor carriers maintain an accident register for three years after each accident meeting the federal definition. The register includes specified facts such as date, city or nearest location, driver name, number of fatalities and injuries, and whether hazardous materials other than fuel spilled. The carrier also retains copies of required state or insurance reports. The driver's timely factual report supports this duty but is not a substitute for the carrier's register.
Post-accident testing depends on the event
A crash does not automatically trigger FMCSA drug and alcohol testing in every case. Under 49 CFR 382.303, a surviving driver performing safety-sensitive functions must be tested after a fatality. For an injury receiving immediate treatment away from the scene or disabling damage requiring tow-away, testing is required when the CMV driver receives a qualifying moving-traffic citation within the regulation's time window. Employers should apply the federal table and any separate company or legal requirements.
Understand testing timing and availability
Required alcohol testing should occur as soon as practicable. If it is not completed within two hours, the employer documents the reason; after eight hours, attempts stop and the employer documents why. Required controlled-substances testing attempts stop after 32 hours if not completed, with a record of the reason. A driver subject to testing must remain readily available, while necessary medical care and obtaining emergency assistance take priority. Call the carrier before leaving whenever circumstances allow.
Do not confuse police testing with carrier testing
A qualifying alcohol or controlled-substances test conducted by law enforcement may satisfy the federal requirement when it conforms to applicable law and the employer obtains the result. The driver should not decide this independently or assume that a hospital screen, breath test, or citation automatically completes the employer's duty. Follow the employer's instructions, identify medical constraints, and document who directed each step.
Finish with a disciplined written report
As soon as practical, create a chronological factual account: dispatch and crash times, exact location, weather and road conditions, traffic controls, vehicle and cargo status, emergency calls, people and agencies contacted, report and citation information, testing directions, medical treatment, towing, evidence preserved, and property released. Separate observations from later information. Review for accuracy, sign only what you understand, retain permitted copies, and route legal or insurance questions through authorized representatives.
