Buying a Trucking Business: Due Diligence Checklist & Red Flags (2026)

Red flag: Significant unexplained variations in revenue or expenses year-over-year, or high owner discretionary add-backs that lack verifiable support.

Ask: Can you provide detailed P&L statements and balance sheets for the past five years, accompanied by tax returns and bank statements for verification?

Red flag: Fuel expenses that don't align with mileage logs, unusually low maintenance costs for an aged fleet, or insurance premiums that seem inconsistent with the fleet size and accident history.

Ask: Please provide a detailed breakdown of all carrier operating expenses, including fuel usage logs, maintenance records, insurance policies and claims history, and driver payroll records for the last three years.

Red flag: A high percentage of accounts receivable (AR) over 60-90 days, or a pattern of slow payments from major clients, indicating potential cash flow issues or customer dissatisfaction.

Ask: Can I review your current accounts receivable aging report and the payment history for your top 10 customers over the past 12-24 months?

Red flag: Lack of detailed maintenance logs, significant outstanding repairs flagged in recent inspections, or an average fleet age exceeding useful economic life without clear replacement plans.

Ask: Please provide a comprehensive list of all fixed assets, including VINs for all trucks and trailers, current mileage, and a complete maintenance history and inspection reports for each vehicle.

Red flag: Multiple recent Out-of-Service (OOS) violations, a DANGER rating, or a high CSA score (Compliance, Safety, Accountability) in any BASIC category.

Ask: What is your current FMCSA safety rating and what are your recent CSA scores? Can you provide your DOT audit history?

Red flag: High driver turnover rates (e.g., >80% annually), frequent hours-of-service violations in logs, or a compensation model significantly below market rates.

Ask: What is your driver turnover rate for the past three years? How do you recruit and retain drivers, and what is your current compensation and benefits structure?

Red flag: Heavy reliance on spot market load boards with consistently low rates, or a lack of established backhaul contracts leading to significant empty miles.

Ask: Describe your typical dispatch process. What percentage of your loads are secured through dedicated contracts versus spot market, and what is your strategy for maximizing backhaul efficiency?

Red flag: Over-reliance on a single or very few customers (e.g., >20-30% revenue from one client), or contracts nearing expiration without renewal commitments.

Ask: Can you provide a list of your top 10 customers, including contract terms, typical freight lanes, and the percentage of your total revenue each represents?

Red flag: Consistently declining freight rates without corresponding cost reductions, or an inability to pass on fuel price increases through surcharges.

Ask: How do you determine your freight rates, and what are the terms of your fuel surcharge agreements with your major customers?

Red flag: Significant new competition entering key operating lanes, or a general decline in the type of freight typically hauled by the business.

Ask: What are your key operating regions, and how do you perceive the current competitive environment and future freight demand in those areas?

Red flag: Seller has made no attempts to diversify or expand, indicating a stagnant growth strategy or limited market opportunities.

Ask: Have you explored opportunities to expand into new freight types, specialized services, or different geographic regions? What were the findings?

Red flag: Negative reviews on industry platforms, a history of unresolved disputes with brokers or shippers, or difficulty securing preferred loads.

Ask: How do you monitor your company's reputation among brokers and shippers, and are there any public reviews or ratings I should be aware of?

Red flag: Any pending suspensions, revocations, or a history of significant violations with the FMCSA or state regulatory bodies.

Ask: Can you provide copies of all current operating authorities, DOT numbers, and state/local permits, along with documentation of any past or pending regulatory actions?

Red flag: Lapsed policies, high premiums due to frequent claims, or insufficient coverage for the type of freight hauled and potential risks.

Ask: Please provide full copies of all current insurance policies, including coverage limits, deductibles, and a detailed claims history for the past five years.

Red flag: Misclassification of employees as independent contractors, or a history of labor disputes, wage claims, or high legal fees related to employment issues.

Ask: Can I review your standard employee contracts and independent contractor agreements, along with your current employee handbook and any records of labor grievances?

Red flag: Non-assignable leases, short remaining lease terms without renewal options, or equipment leases with unfavorable purchase options.

Ask: Please provide copies of all current property and equipment lease agreements, specifically pointing out assignability clauses, renewal options, and any personal guarantees required.

Red flag: Seller unwilling to commit to a sufficient transition period (e.g., less than 30-60 days) or unclear on their role post-sale, indicating potential knowledge gaps for the new owner.

Ask: What is your proposed timeline and level of involvement for the post-sale transition period, and what specific responsibilities do you envision during that time?

Red flag: Crucial employees (e.g., dispatchers, maintenance manager) express uncertainty about staying, or there's no proactive plan to incentivize their retention.

Ask: How do you plan to introduce me to your key employees, and what steps can we take to encourage their continued employment after the sale?

Red flag: Seller expects the buyer to independently initiate all customer and vendor introductions without personal handover.

Ask: What is your strategy for introducing me to your key customers, brokers, and critical vendors to ensure a smooth transition of relationships?

Red flag: Proprietary or unsupported software systems, or a lack of clear documentation and training for existing technology.

Ask: What transportation management systems (TMS), electronic logging devices (ELDs), and other software systems are currently in use, and what is the plan for transferring access and providing training?
