Communication is a core skill for every commercial driver. You interact with dispatch, shippers, receivers, law enforcement, other drivers, and the general public — often all in the same day. How you communicate affects your safety, your pay, your carrier's reputation, and your career. This guide covers the three main channels of external communication: CB radio, dispatch, and customer service at facilities.
CB Radio: Channel Guide and Etiquette
The Citizens Band (CB) radio is still widely used by truck drivers for real-time road information. While smartphones have replaced many CB functions, it remains the best tool for immediate communication with drivers around you. Here's what you need to know:
Channel Guide
- Channel 19: The standard trucking channel — traffic reports, road conditions, speed traps, and general communication
- Channel 9: Emergency channel — reserved for emergencies and assistance requests only
- Channel 17: North/Southbound traffic (common in some regions)
- Channel 21: East/Westbound traffic (common in some regions)
- Channels 1–8 and 11–14: General use, less congested
Etiquette Rules
- Keep it short: Limit transmissions to 30 seconds. Say what you need and get off the key.
- No profanity: The FCC prohibits obscene language on CB radio. Keep it professional.
- Use a handle: Identify yourself with a CB handle (nickname). Don't transmit without identifying.
- Wait for a clear channel: Listen before transmitting. Don't talk over someone.
- Don't use Channel 19 for chat: Personal conversations clog the channel. Move to another channel.
- Acknowledge information: If someone gives you a road report, a quick "10-4, thanks" is courteous.
- Be helpful: If you see a hazard, accident, or speed trap, report it. The CB community works when everyone contributes.
Dispatch Communication: Status Updates and Protocols
Your dispatcher is your lifeline. They assign loads, track your progress, handle problems, and get you paid. Clear, timely communication with dispatch is essential. Here's the standard protocol:
Milestone Reporting
Report your status at every milestone. Don't wait for dispatch to ask:
- Dispatched: Confirm you received the load assignment and are heading to pickup
- Arrived at shipper: Report arrival time
- Loaded: Confirm cargo is loaded, BOL signed, and you're departing
- En route: Provide ETA to receiver
- Arrived at consignee: Report arrival time
- Unloaded: Confirm delivery is complete, paperwork signed
- Available for next load: Tell dispatch you're ready for the next assignment
Reporting Delays and Problems
- Report delays immediately — don't wait. If you're going to be late, dispatch needs to know ASAP to adjust the delivery appointment.
- Be specific — "I'm delayed 3 hours due to a tire change at the Pilot in exit 42" is better than "I'm running late."
- Report problems with solutions — "The receiver is closed. Should I wait until morning or divert to the drop lot?"
- Keep records — note the time and content of dispatch communications in case of disputes
- Never use a handheld phone while driving — use hands-free or pull over. FMCSA rules apply to dispatch calls too
Customer Service at Shippers and Receivers
When you arrive at a shipper or receiver, you represent your carrier. Your professionalism directly affects your carrier's relationship with that customer — and whether you get loaded or unloaded on time. Follow these steps:
- Check in at the gate or office: Present your photo ID and BOL. Be polite to security and clerks — they control your loading/unloading time.
- Follow site rules: Obey speed limits (often 5 mph), wear required PPE (hard hat, safety vest, steel-toe boots), park in designated areas only.
- Be patient: Loading and unloading can take hours. Don't complain — use the time to inspect your truck, eat, or rest.
- Inspect the cargo before signing: Verify the count and condition match the BOL. Note any discrepancies before you sign.
- Get signed paperwork: Ensure the receiver signs and dates the delivery receipt. Keep your copy — you need it for payment and in case of claims.
- Say thank you: A simple "thank you" to the dock workers and clerks goes a long way. Drivers who are rude get loaded last.
Professional Communication Standards
- Be clear and concise — say what you mean, avoid rambling
- Use proper terminology — "BOL," "consignee," "shipper," "ETD," "ETA" — not slang
- Keep emotions in check — even when frustrated, stay calm and professional
- Document important conversations — note date, time, who you spoke with, and what was agreed
- Respond promptly — when dispatch or a facility contacts you, respond as soon as safely possible
- Never argue with law enforcement — comply with instructions, contest violations in court if needed
- Be honest — if you made a mistake, admit it. Lying about a delivery time or cargo damage always makes things worse
