How to Prove a Truck Driver Was Texting and Driving
Operating an 80,000-pound commercial vehicle requires absolute concentration. Yet, distracted driving remains one of the leading causes of devastating rear-end collisions on American highways. When a truck driver takes their eyes off the road for just five seconds at 65 mph, they travel the length of an entire football field entirely blind.
The Federal Motor Carrier Safety Administration (FMCSA) strictly prohibits commercial drivers from texting, holding a mobile phone, or reaching for a device while driving (49 CFR § 392.80). If you suspect distraction caused your crash, knowing exactly how to prove a truck driver was texting and driving is the key to holding both the driver and the motor carrier financially accountable.
Truck drivers will rarely admit to police that they were texting. Your attorney must formally subpoena the driver's cellular provider (Verizon, AT&T, etc.) for their billing and data usage records. By comparing the exact timestamp of the 911 call with the timestamp of an outgoing text message or data upload, we can definitively prove the driver was active on their phone at the moment of impact.
Three Methods to Expose Distracted Driving
Cell phone records are not the only way to catch a distracted driver. A thorough legal investigation utilizes several layers of technology to uncover the truth:
Many modern trucking fleets install dual-facing dashcams (such as Lytx or Samsara) to monitor their employees. Your lawyer will send a spoliation letter immediately to prevent the company from deleting the inward-facing footage, which will visually show the driver holding a phone or staring downward into their lap before the crash.
Sometimes the distraction is not a smartphone, but the truck's own built-in communication tablet. Dispatchers often send urgent messages to drivers regarding delivery times. If the fleet telematics log shows the driver was tapping the screen to reply to dispatch while the truck was moving at 70 mph, the corporation itself is liable for encouraging the distraction.
An awake, attentive driver will apply the brakes or attempt evasive steering before a crash. If the truck's Black Box shows absolutely zero brake pressure applied in the seconds leading up to a rear-end collision, it strongly suggests the driver's eyes were completely off the road.
