The Chain of Responsibility Nobody Talks About: How Substance Use Ripples
Through Transport Operations
The driver had an addiction problem. Nobody knew—or nobody wanted to know. He was still showing up to work. Still completing deliveries. Just… different. Quieter. Sometimes erratic. Sometimes missing shifts.
But the culture was: as long as work gets done, it’s not our problem.
Then came the near-miss. A customer complained the driver seemed impaired during delivery. Investigation revealed substance use. The driver was offered help. He declined. Company faced choice: accommodate someone actively using, or let them go.
They chose to terminate. But here’s what the company missed: that driver’s impairment didn’t just affect him. It affected:
- The dispatcher who’d been covering his missed shifts
- The customers whose deliveries were sometimes unpredictable
- The other drivers whose loads got rerouted when he didn’t show
- The company’s reputation (word spread in the industry)
- The mechanics doing extra maintenance checks on his vehicle
- The scheduling systems that had to work around his absences
- The younger drivers learning that substance use issues were manageable if you stayed quiet
One driver’s substance use created ripples affecting dozens of people and systems. The company only saw the direct cost (one terminated employee). They missed the hidden costs distributed across operations.
Substance Use Isn’t Just a Driver Problem
Transport companies often frame substance use as individual problem: “Some drivers use drugs. We test for it. Problem solved.”
This misses critical reality: substance use is an operational and cultural problem affecting entire organizations.
How substance use ripples through transport:
Scheduling Disruption: Impaired or unreliable driver means loads get reassigned. Other drivers work extra hours to cover absences. Schedulers spend time managing around known problem person.
Maintenance Issues: Drivers using substances often have vehicle incidents—minor damage, equipment problems—from impaired judgment. Mechanics spend time fixing problems that shouldn’t exist.
Customer Relationship Damage: Unreliable or impaired service affects customer trust. One bad customer experience from substance-impaired driver damages relationships built over years.
Safety Culture Degradation: When substance use is visible and ignored, safety culture suffers. Message becomes: “We tolerate impaired people as long as work happens.”
Recruitment Impact: Word spreads. Substance use problems are known in transport communities. Companies known for tolerating use attract workers with similar problems and repel safety-conscious workers.
Peer Pressure: Younger drivers seeing substance use tolerated normalize the behavior. Culture shifts toward accepting that some level of substance use is normal.
Operational Unpredictability: With substance-impaired drivers in workforce, operations become unpredictable. You can’t rely on consistent service, regular attendance, or consistent quality.
Why “Testing” Isn’t Strategy
Many companies think drug testing addresses substance use. Test positive, remove from duty, problem solved.
But testing is detection, not prevention. And detection only happens if someone is tested.
The gaps in testing-only approach:
- Pre-employment testing catches some problems but doesn’t address current workforce
- Random testing is infrequent; substance use often happens between tests
- Some substances clear system quickly; testing happens after substance is undetectable
- Workplace culture that doesn’t discuss substance use means people hide problems until they become incidents
Testing is important for safety-sensitive roles. But it’s not substance use strategy. It’s incident prevention if substance use is happening.
What Real Substance Use Awareness Means
Genuine awareness isn’t just “drugs are bad.” It’s understanding:
How Substances Affect Transport Work: What drugs do to judgment, coordination, reaction time, and decision-making. Why impairment is dangerous in roles involving vehicle operation and safety decisions.
Signs of Substance Use: Recognizing when colleagues might be struggling. Not to be judgmental, but to intervene before incidents occur.
Supportive Response vs. Punitive: Understanding that substance use is often health issue, not moral failing. Creating environment where people disclose problems before they become safety issues.
Chain of Responsibility Implications: Understanding how substance use affects chain of responsibility. If driver is impaired and involved in incident, liability cascades through entire organization.
When to Escalate: Understanding when substance use is safety issue requiring action. When to involve management, occupational health, regulatory bodies.
Recovery and Support: Understanding that substance use treatment exists and works. Companies that support recovery often recover valuable workers.

KRTS: Understanding Transport’s Real Challenges Since 1990
We’ve trained transport workers for 35 years. We understand the real drivers of substance use in transport: isolation, fatigue, stress, shift work, chronic pain from injuries. We understand that punitive approaches don’t work, but supportive culture prevents problems.
This isn’t generic substance abuse training. It’s awareness designed for transport industry realities.
Create Culture Where People Get Help
Alcohol and drugs awareness for $50.
Stop treating substance use as individual problem. Build operational and cultural approach addressing how substance use ripples through organizations. Create environment where people struggling seek help before problems become incidents.
