Distracted Driving Rules for CDL Drivers

Distracted driving is the leading cause of preventable commercial vehicle crashes. The FMCSA has some of the strictest distracted driving rules in the country — and they apply only to commercial drivers operating a CMV. A single violation can cost you your license, your job, and thousands in fines. This guide covers every rule you need to know, the exact penalties, and how to stay compliant.

The FMCSA Distracted Driving Rules (49 CFR 392.82)

The FMCSA issued its final rule on distracted driving in 2010, and it has been strictly enforced since. The rule applies to all commercial motor vehicles (CMVs) operating in interstate commerce. Here's what it prohibits:

No Texting

Texting is broadly defined. It includes sending, reading, or manually typing any text-based communication on a mobile device. This covers SMS texts, emails, instant messages, and even typing a web address. Pressing a single button to initiate or terminate a call is the only allowed manual interaction with a phone.

No Handheld Phone Use

You may not hold a mobile phone to make or receive a call. You may not reach for a phone in a way that requires you to leave a seated, belted position. You may not dial by pressing more than one button. The only compliant way to use a phone while driving is with a hands-free device that allows one-touch or voice-activated dialing, and the phone must be mounted in a cradle.

When Do the Rules Apply?

The rules apply whenever the vehicle is in motion on a roadway or when the vehicle is temporarily stopped at a traffic control device (red light, stop sign, or in traffic). They do NOT apply when the vehicle is safely parked off the road — that's when you can make calls, send texts, or check your phone freely.

Penalties: Fines and License Suspension

Two or more violations also result in a disqualification from operating a commercial vehicle. Some states impose additional penalties on top of the federal fines — including points on your driving record and potential misdemeanor charges.

The Only Exemption: Emergencies

The only exemption is using a handheld phone to contact law enforcement or emergency services in an emergency. This means calling 911 to report an accident, a road hazard, or a crime. There are no exemptions for:

• Personal phone calls (even urgent ones)
• Dispatch or work-related communications
• Checking GPS or navigation apps (use a mounted device)
• Texting your dispatcher to say you're running late
• Reading a message from a family member

How to Stay Compliant on the Road

• Mount your phone in a cradle on the dashboard or windshield. It must be hands-free at all times while driving.
• Use a Bluetooth headset or speaker for calls. Set up one-touch speed dial for your dispatcher and key contacts.
• Pull over to text. If you need to send or read a message, find a safe parking area first. Even at a red light, texting is a violation.
• Set GPS before you move. Enter your destination into your navigation app while parked. Do not type while driving.
• Use a dispatch device that's mounted and hands-free. Some Qualcomm/Elog devices have messaging — but only use them when safely parked.
• Train yourself to ignore notifications. Turn off non-essential alerts while driving. Every glance at your phone is a risk.
