Nobody admits to looking at a phone. That one sentence explains why these cases turn on documents rather than testimony.
Proving truck driver distraction means reconstructing a few seconds from machines that were watching. Federal researchers have also measured which activities actually raise risk, and the answers contradict most lists published on the subject.
Below, we explain what the data shows and what it refutes. We also cover which records hold the proof and how fast they disappear.
Why Proving Truck Driver Distraction Starts With the Records
Three systems were running inside that truck. The electronic logging device, the engine control module, and often a camera all recorded something.
None of them records a phone call. Each one, however, fixes the truck in time and place, which is what makes a carrier’s phone records usable.
Every one of those systems also overwrites. The clock starts at impact, and it runs faster than most people expect.

Federal researchers put cameras in 203 trucks and collected roughly three million miles of driving. The resulting report, Driver Distraction in Commercial Vehicle Operations (FMCSA-RRR-09-042, September 2009), assigned odds ratios to individual tasks.
Read the top of that list. Text messaging came in at 23.24, a dispatching device at 9.93, writing on a pad at 8.98. Looking at a map scored 7.02 and dialing a phone 5.93.
Reaching for an object reached 3.09. Personal grooming hit 4.48, the only everyday personal task on the elevated side.
One limit belongs on every one of those numbers. The study measured safety-critical events: crashes, near crashes, conflicts, and lane deviations. Nobody should say texting makes a crash 23 times more likely.
A 2021 follow-up repeated the exercise. Published as FMCSA-RRR-20-003, it found the same pattern twelve years later, with truck texting at 8.71.
The Tasks That Did Not Show Elevated Risk
Here the legacy lists fall apart. Researchers measured several activities commonly named as truck distractions, and those came back flat or lower.
Look at the figures. Eating registered 1.01, drinking 0.97, and smoking with a cigarette in hand 0.97. Talking on a hand-held phone reached 1.04, with a confidence interval spanning 1.0.
Three came back protective. Interacting with another occupant measured 0.35, looking at something outside the vehicle 0.54, and hands-free phone conversation 0.44.
CB radio use landed at 0.55. The researchers wrote that hands-free conversation “provided a significant protective effect,” as did citizens band radio.
Their explanation is mechanical. “Listening and talking,” they noted, “does not draw the eyes away from the forward road.”
Do not misread those numbers, though. Drivers converse when driving is easy, so self-regulation explains much of the effect. Measured risk lives in tasks that move the eyes and hands. Chatting does not improve safety.
Why the Biggest Risk Is Not the Biggest Problem
Odds ratios answer only half the question. The same report also calculated how much of the total risk each task actually accounts for.
That column reorders everything. Reaching for an object carried 7.6 percent of population attributable risk, the highest of any task. Texting carried 0.7 percent, because it happens rarely.
So a case built only on texting may miss what happened. Reaching, dispatching screens, and paperwork appear far more often.
What Two Seconds Does
Glance duration gave the clearest threshold in the study. Eyes off the forward road for more than two seconds produced an odds ratio of 2.93.
Shorter glances behaved oddly. Between half a second and a second and a half, the figures sat near 1.0 without statistical significance. The relationship is therefore not a smooth curve.
Texting explains why it matters. That task averaged 4.6 seconds of eyes off the road within a six-second window.
The Two Federal Bans, and Their Gaps
Two regulations govern phones in commercial trucks. Section 392.80 forbids texting while driving, and § 392.82 forbids using a hand-held mobile telephone.
Both bind the company as well. No carrier “shall allow or require its drivers” to do either one.
The definitions decide close cases. “Use a hand-held mobile telephone” covers holding a phone and pressing more than a single button to dial or answer. It also covers “reaching for a mobile telephone” in a way that breaks the seated, belted driving position.
Two gaps matter. “Mobile telephone” expressly “does not include two-way or Citizens Band Radio services.” Each ban also defines driving to exclude a truck moved off the highway and halted safely.
Red lights offer no shelter. Both sections reach a driver “temporarily stationary because of traffic, a traffic control device, or other momentary delays.”
Why Georgia Law Does the Heavier Work
A detail here surprises most people, including some lawyers. No Georgia appellate decision holds that violating a federal motor carrier regulation is negligence per se.
Georgia supplies its own command instead. Under O.C.G.A. § 40-1-8(h)(2), a motor carrier or commercial driver “shall comply” with the safety standards in 49 CFR Part 392. Both phone bans sit inside that part, and subsection (j) makes a violation a misdemeanor.
That changes the argument. The federal regulation supplies the content of the duty, while a Georgia statute supplies the duty itself.
Georgia’s hands-free statute adds a second route. Section 40-6-241 bars holding a device, along with writing, sending or reading text-based communication. Subsection (d) then adds commercial-driver rules mirroring the federal definition almost word for word.
Notably, that statute contains no evidentiary carve-out. Some states bar using a hands-free violation in a civil case, and Georgia does not.
What the Penalties Actually Are
Published figures on this topic are badly out of date, including FMCSA’s own pages. Those still quote $2,750 and $11,000 from the 2011 rulemaking.
Current numbers sit higher. Appendix B to Part 386 caps a driver’s civil penalty at $4,812, and a carrier’s at $19,246 per violation.
A license consequence follows repeat convictions. Under § 383.51, a second serious traffic violation within three years costs 60 days of commercial driving privileges. A third costs 120.
The Evidence Clock
Now the part that decides whether any of this gets proven.
Three retention facts shape the timeline. No federal rule requires a carrier to keep dash camera footage at all. Electronic logging records survive only six months. Engine modules typically hold one to three hard-braking events before overwriting them.
Georgia law supplies the answer. Under Phillips v. Harmon, 297 Ga. 386 (2015), the duty to preserve evidence attaches “not only when litigation is pending but when it is reasonably foreseeable to that party.”
Severity triggers that duty. Sending a rapid-response team, calling the insurer, or pulling the truck from service each shows the carrier foresaw a claim.
