When Driving Is the Job: Concussion Questions for Jacksonville Providers Treating Commercial Drivers After a Crash
Northeast Florida's port, rail yards and interstate corridors put many professional drivers on the road. After a crash they are often eager to get back to work, and symptoms can be underreported. Intake questions, return-to-driving considerations and where testing fits.
Who this is for: Written for chiropractors, primary care and urgent care physicians, orthopedists and physical therapists in Jacksonville, Orange Park, Fernandina Beach and St. Augustine who treat truck, delivery and other professional drivers after a crash.
A 51-year-old tractor-trailer driver comes to your Westside office for neck and shoulder pain after another truck sideswiped him on I-10 near the I-295 interchange. On the intake form he checks "no" for head injury. When you ask directly, he mentions a headache that has not let up, losing track of a route he has driven for years, and that he is due back on the road Monday. This is a hypothetical example.
Professional drivers are a common part of a Northeast Florida caseload. Port terminals on Blount Island, distribution centers along the I-95 and I-10 corridors, and package and food delivery across Duval, Clay, St. Johns and Nassau counties all depend on them.
Key takeaways
- Duval County recorded 2,797 crashes involving a commercial motor vehicle in 2024, with 837 people injured (FLHSMV).
- Professional drivers often have strong reasons to say they are fine after a crash.
- In a small simulator study, drivers tested soon after becoming symptom-free still had more lane excursions (Schmidt et al., 2017).
- Ask for, and give, written instructions about returning to driving (CDC).
The local picture
Florida's 2024 Traffic Crash Facts report counts 2,797 crashes involving a commercial motor vehicle in Duval County, with 15 deaths and 837 people injured. St. Johns County recorded 551 such crashes with 133 injured, Clay County 326 with 71 injured, and Nassau County 192 with 48 injured. Those injury totals include everyone in the crash, not only the commercial driver.
"I’m fine, I need to get back on the road" is where many concussion histories stop.
Why symptoms get underreported
Drivers paid by the mile or the stop have a strong reason to say they are fine. Some worry about their medical certificate, their job or their schedule. Others simply attribute headaches, fatigue and poor sleep to long hours. The CDC notes that some concussion symptoms may not appear for hours or days, and that people may not recognize or admit that they are having problems.
Questions that tend to surface what the form missed:
- "Since the crash, have you missed a turn, an exit or a delivery stop you normally know well?"
- "Are bright sun, headlights or dashboard screens bothering you more than before?"
- "Are you more tired at the end of a shift, or making more small mistakes?"
- "Has anyone at work or home noticed a change in your mood or patience?"
Document the answers, even when they are negative, along with the mechanism of injury, any head strike, airbag deployment and how the patient felt in the first hours.
Returning to driving
Federal rules set the medical standards for interstate commercial drivers. Under 49 CFR 391.41, a driver must have no condition likely to cause loss of consciousness or any loss of ability to control a commercial motor vehicle, and no mental, nervous, organic or functional disease likely to interfere with safe driving. Medical certification is performed by examiners certified by FMCSA and listed on the National Registry of Certified Medical Examiners, as defined in 49 CFR 390.5.
Symptom resolution may not mean full readiness. In a small simulator study by Schmidt and colleagues, 14 young adults tested within 48 hours of becoming symptom-free after a concussion had more lane excursions than matched controls and poorer vehicle control on curves. The authors noted that driving impairments may persist beyond when people return to driving. The study did not involve commercial drivers, but it supports caution.
The CDC encourages patients to ask their provider for written instructions about returning to activities such as driving. A clear, dated note helps the driver, the employer and any later reviewer. For a patient-friendly overview to share, see when it is safe to drive after a concussion. For patients whose symptoms blur with stress, see concussion or stress after a crash.
Where testing fits
When you decide testing makes sense, Braintree's mobile team performs concussion and TBI testing at your office in Jacksonville, Orange Park, St. Augustine, Fernandina Beach and nearby communities, and scheduling is coordinated with your staff. Results come back as physician-reviewed diagnostic reports. The report goes to a neurologist ahead of the neuro evaluation, and the referring provider then receives a copy to guide advanced imaging and treatment recommendations.
