Distracted driving in a commercial fleet is any activity that pulls a driver's attention from driving, and for CMV drivers the federal rules, the crash research, and the carrier's own exposure all point the same way: handheld phones and texting are prohibited, and the carrier is responsible for not allowing or requiring them. NHTSA groups distraction as visual, manual, and cognitive, and the worst tasks combine all three.
This Heavy Duty Journal guide checks the rules and the research against FMCSA and NHTSA sources, then covers policy, monitoring, and documentation. It drops crash-cost averages, verdict statistics, and state fine ranges that could not be traced to a primary source, and says so in the cost section.
Key Takeaways
- ✓Texting carried a 23.2 times higher crash risk. FMCSA-commissioned research found the odds of a safety-critical event were 23.2 times greater for CMV drivers who text, with eyes off the road for an average of 4.6 seconds.
- ✓Employers are covered by the rules. FMCSA prohibits employers from allowing or requiring hand-held phone use or texting, and its fact sheets list penalties of up to $11,000 for employers.
- ✓Texting violations carry the maximum severity weight. FMCSA says they hurt SMS results at the maximum weight, so a phone habit can show up in the carrier's CSA data.
- ✓Nationally, 3,208 people died in 2024 distraction-affected crashes. NHTSA reports that figure, 8 percent of 39,254 deaths, and says distraction is likely underreported.
- ✓A written policy is not federally required, but it is your evidence. FMCSA says the rule does not require written policies, yet a clear policy shows the carrier does not allow or require hand-held use.

Distracted Driving in Commercial Fleets: What the Evidence Says
FMCSA-commissioned research found that the odds of a safety-critical event, such as a crash, near-crash, or unintentional lane deviation, were 23.2 times greater for CMV drivers who text while driving. Texting drivers took their eyes off the forward roadway for an average of 4.6 seconds, which at 55 mph is about 371 feet. See the FMCSA no-texting fact sheet.
23.2×
Higher odds of a safety-critical event for CMV drivers who text while driving, per FMCSA's no-texting fact sheet. Texting drivers looked away from the road for an average of 4.6 seconds.
Nationally, NHTSA reports 3,208 people killed and an estimated 315,167 injured in 2024 crashes involving distracted drivers. That is 8 percent of the 39,254 deaths, and NHTSA notes limits in how distraction is coded, so the true figure is likely higher. See its Distracted Driving in 2024 research note.
For trucks specifically, FMCSA's Large Truck Crash Causation Study of 2001 to 2003 crashes coded inattention on 9 percent of trucks with a relative risk of 17.1, external distraction on 8 percent (5.1), and internal distraction on 2 percent (5.8). The data are old, so use them as a ranking of risks.
What FMCSA Rules Require
Under 49 CFR 392.80, a CMV driver may not text while driving. FMCSA defines texting as manually entering text into, or reading text from, an electronic device, including text messages, email, instant messaging, requests to access a web page, and pressing more than a single button to start or end a call. Dispatching devices that are part of a fleet management system can be used for other purposes, but FMCSA says texting on one is prohibited.
Under 49 CFR 392.82, a driver may not use a hand-held mobile phone while driving. That means holding a phone to make a call, dialing by pressing more than a single button, or reaching for a phone in a way that takes the driver out of the seated driving position restrained by a seat belt. A phone must be placed so a driver can start, answer, or end a call with a single touch. See the FMCSA mobile phone fact sheet.
Employers are covered. FMCSA's fact sheets list penalties of up to $2,750 for drivers and up to $11,000 for employers who allow or require hand-held use or texting. Those amounts are from FMCSA's published sheets, and civil penalty amounts are adjusted periodically, so check the current table before quoting them. Multiple violations can also lead to CDL disqualification of up to 120 days.
FMCSA also says these violations carry the maximum severity weight in the SMS. HDJ's CSA score guide explains how SMS data is used. The rule does not require a written company policy, but a written rule that the carrier does not allow or require hand-held use is the clearest way to show it.
Beyond Phones: Other Distractions
A driver who is not on a phone can still be distracted. Eating, adjusting equipment, a roadside incident, and mental drift all take attention, and inattention and distraction show up in the crash data above. Behaviors such as following too close, late braking, and lane drift are warning signs worth coaching, even when no device appears on camera.
In-cab technology belongs in the policy. Program navigation before departure, limit manual input while moving, and review how dispatch and ELD screens ask drivers to interact. FMCSA allows ELD and dispatch devices for permitted purposes, but texting on them is texting.
Dispatch practice is part of the risk. A driver who expects consequences for a slow reply has a reason to check a screen. Set a written standard for non-urgent contact, use voice or pre-set messages where practical, and make clear that a driver is never expected to answer while moving.
Cost Exposure and What We Could Verify
The cost of a distracted driving crash is real, but most widely quoted figures are weakly sourced. This article does not repeat per-crash averages, uninsured-loss multipliers, or nuclear verdict medians, because the sources behind them could not be verified. ATRI published a trucking litigation analysis in December 2025, which you can request from ATRI for current verdict data.
One cost trend is verified. ATRI reports that trucking auto liability premiums rose 36 percent per mile over eight years even as truck crashes declined over the past four, per its November 2025 release. A crash with a phone in a driver's hand is the kind of fact an insurer or plaintiff will look at, so assume phone records can become evidence and ask counsel how to preserve and review them.
Weigh the program against what you can measure in your own fleet: crash and claim costs, deductible payments, downtime, and premium changes. HDJ's commercial truck accident prevention guide covers what the crash data says about priorities.
Building a Prevention Program
Start with a written policy. Prohibit hand-held use and texting without exception for stopped-in-traffic situations, set rules for hands-free use that keep the phone within single-touch reach, require navigation to be programmed before departure, and set the dispatch contact rules. Have each driver sign it and keep the record.
Key Recommendation
Write the dispatch rules into the distracted driving policy: when dispatch may contact a moving driver, by what channel, and what response time is not expected.
Train on the three types of distraction and the FMCSA findings, then coach on specific events. A short conversation soon after a flagged event works better than a general refresher. HDJ's fleet driver safety program guide covers how training, monitoring, and incident response fit together.
Use monitoring to see patterns. Telematics can show hard braking and speeding, and driver-facing cameras can flag phone use and attention lapses, with real-time alerts on some systems. HDJ's AI driver safety monitoring guide covers the tools. HDJ's fleet driver management software guide covers scorecards. Treat vendor crash-reduction percentages as claims to test, not facts.
Phone-blocking and do-not-disturb tools add a technical barrier, but they work only on company devices unless your policy covers personal phones. Technology supports the program; it does not replace the policy, the coaching, or the dispatch rules.
Footage, Privacy, and Documentation
Cameras bring privacy and legal questions. Tell drivers what is recorded, when, who sees it, and how long it is kept, and put it in writing before deployment. Many fleets record only triggered events, and drivers often accept cameras once footage is used to resolve disputed claims as well as to coach.
Retention rules depend on your state, your insurer, and your litigation risk. Ask counsel for a written retention and deletion policy, including how incident footage is preserved after a crash, and follow it consistently. Keep training records, signed policies, coaching notes, and discipline records, because documentation shows a program exists and is enforced.
Measuring Results
Track a few numbers over time: flagged phone-use events per driving hour, hard-braking rate, coaching sessions completed, policy violations per quarter, and at-fault crashes per million miles. Set a baseline before you change anything, and review quarterly.
Bring the trend to insurers at renewal and keep records of what you changed. Do not assume a particular premium effect: ask your insurer which data it values, and measure your own claims and crashes.
Owner-Operators and Small Fleets
Owner-operators under their own authority face the same texting and hand-held rules and the same civil penalties. A short written policy, a phone set to silence while driving, navigation programmed before departure, and a fixed mount within single-touch reach cost little and show how you operate.
Consider a driver-facing camera for protection against disputed claims, and check with your insurer about whether it values one. HDJ's truck driver safety tips guide covers day-to-day habits.
Frequently Asked Questions
What does FMCSA say about texting while driving a CMV?
49 CFR 392.80 prohibits texting while driving a CMV. FMCSA's fact sheet lists penalties up to $2,750 for drivers and $11,000 for employers who allow or require it.
Can drivers use hands-free phones?
Yes, if the phone is within reach so a driver can start, answer, or end a call with one touch while seated and belted. Holding the phone or dialing with several buttons is prohibited.
Is a written distracted driving policy required?
FMCSA says the rule does not require written policies, but employers may not allow or require hand-held use. A written policy and signed driver acknowledgments help show that the carrier does not.
How many people die in distraction-affected crashes?
NHTSA reports 3,208 deaths in 2024 distraction-affected crashes, 8 percent of 39,254 deaths, and says the number is likely underreported because distraction is hard to code.
Do dashcams reduce distracted driving?
They can help when someone reviews alerts and coaches drivers. Vendor percentages vary and are hard to compare, so measure your own events and crashes before and after deployment.
The Bottom Line
Distracted driving prevention for a commercial fleet comes down to four things: follow the texting and hand-held rules, set dispatch expectations that do not push drivers to answer while moving, coach on real events, and keep records. The evidence is strongest on texting, and weakest on costs.
Heavy Duty Journal's guidance at heavydutyjournal.com, from publisher Michael Nielsen and the HDJ editorial team, is to write the policy first, fix dispatch practices, and verify every statistic against its source.
As of October 2026, FMCSA penalty amounts and state laws change, so confirm current figures before relying on them.
