To negotiate freight rates above posted: pull the lane's 7-day DAT average, quote it back to the broker, lead with your MC/DOT and equipment specifics, and open at $0.15–$0.30/mi above posted. Never accept the first counter — brokers post 8–15% below what they'll pay. Ask for detention after 2 hours and TONU in writing.
Before you dial: 90 seconds of research
Open DAT One, pull the 7-day and 15-day rate average on the specific lane origin→destination for your equipment. Note the load-to-truck ratio (>3 loads per truck = tight market, negotiate hard; <1.5 = soft, take posted).
Also check the broker's DAT credit score. Under 90 days average pay or under 90 credit score, either walk or require quick-pay/factor confirmation up front.
The opening script
"Hi, this is [name] with [carrier name], MC 123456. I've got a 53-foot dry van empty in Atlanta at 3 p.m. tomorrow, running clean CSA. I'm looking at your Atlanta→Memphis load. DAT 7-day on that lane is $2.65/mi all-in and you're posting $2.20. I can be there for $2.55 all-in with detention after 2 hours and TONU of $250 in writing on the rate con. Does that work?"
Notice: specific equipment, credibility signal (MC + CSA), market data, opening offer that includes the ask, and the two accessorials most brokers agree to.
How to handle the broker's counter
Broker: "I can do $2.35." You: "I appreciate that. My cost on this lane is $2.10 all-in and I need at least $0.30/mi margin to make my day. Meet me at $2.45?"
Rule: split every counter. If they move 15¢, you move 10¢. If they don't move at all after two exchanges, thank them and hang up. There's another load.
The accessorial line that pays for itself
"Detention after 2 hours at $75/hr" written on the rate confirmation gets paid ~70% of the time when you invoice it with photo timestamps and driver logs. Without it in writing, closer to 20% collection.
One paid detention claim per week ($150–$300) is 4–5x the negotiation effort's ROI.
The 3-number opener that beats posted rate
Open with three data points: DAT 7-day paid average on the lane, your operating cost floor on that trailer type, and the reload rate at destination. Naming all three signals you know the lane and pushes the broker off their opening quote by $0.10–$0.20/mi on the first call.
Never take the first counter. The broker's opening is always 8–15% below their approved max — they expect a counter and the load-planner desk builds it into the target rate.
Accessorials brokers will pay when asked
Detention after 2 hours at $75/hr, TONU at $150–$250 for a live cancel, layover $150–$250/day, driver-assist unload $75–$150, tarp fee $50–$100 on flatbed, and stop-off $50 per additional stop.
These are printed on most brokers' standard rate confirmations — they only get denied when the carrier does not ask before dispatch or does not document in-times and out-times on the BOL. Ask for accessorials in the rate email, not after the fact.
Frequently asked questions
What if the broker says no?
Politely thank them and move on — there's another load on the board. Brokers remember polite negotiators and call them first next week.
Should I share my cost-per-mile with brokers?
Yes, selectively. Sharing 'my cost is $2.10' is a credible anchor. Sharing your net or personal financials is not.
How often do brokers post fake loads?
Rare on DAT and Truckstop — accounts get closed. More common on Facebook groups. Verify with a call before adjusting your day around a posted load.
