For freight brokers, carrier selection has always involved balancing multiple factors.
Operating authority. Insurance coverage. Inspection history. Safety performance. Capacity. Service. Cost.
Each provides an important piece of the picture. But when it comes to safety, many of the measures brokers rely on have something in common: they tell you what has already happened.
An accident occurred. A violation was recorded. An inspection found a problem. A safety score changed.
Those are important signals, but they raise another question that may deserve more attention: What is a carrier doing to prevent the next safety event from happening in the first place?
Looking Upstream at Risk
Some of the most valuable safety practices may never appear in a safety score because, when they work, the incident never happens.
Consider driver screening.
Every motor carrier operating under DOT requirements must maintain a compliant drug and alcohol testing program. Those requirements establish an essential safety baseline.
But some carriers choose to go beyond that baseline.
One example is the use of hair testing alongside federally required drug testing during pre-employment screening.
Why?
Because different testing methods provide visibility into different periods of drug use. Urine testing generally detects more recent use, while hair testing can provide approximately a 90-day window into patterns of drug use.
For a carrier making a hiring decision, that additional visibility can matter.
Psychemedics compared more than 1.2 million commercial-driver pre-employment tests. Hair testing produced a 5.55% positivity rate compared with 0.59% for urine testing, approximately 9 times the rate of drug use identified.
That doesn’t mean one method replaces the other. Federally required testing remains essential.
What it does illustrate is that meeting a testing requirement and gaining greater visibility into potential risk aren’t necessarily the same thing.
Why Should a Freight Broker Care?
Freight brokers aren’t responsible for managing their carriers’ drug-testing programs.
But brokers are responsible for deciding which carriers they trust with their customers’ freight.
And the steps a carrier takes before a driver ever gets behind the wheel can tell you something about that carrier’s overall approach to safety.
Does it view compliance as the finish line?
Or does it actively look for opportunities to identify and reduce risk before it becomes an accident, violation, or claim?
Driver screening is only one part of that conversation. Training, equipment maintenance, safety culture, hiring standards, and management practices all matter.
Adding Prevention to the Carrier Conversation
This doesn’t have to mean creating another complicated carrier qualification process.
It may simply mean asking better questions.
What does the carrier do beyond minimum safety requirements? How does it evaluate drivers before hiring them? What additional safeguards has it voluntarily adopted? How does management think about preventing risk rather than responding to it?
Those questions can add context to the historical information brokers already evaluate.
Because ultimately, the strongest carrier network may not simply be the one with the best record today.
It may be the one made up of carriers doing the most to prevent tomorrow’s incident.
