A 2026 survey of 1,060 current and former U.S. CDL holders on cost, time off the road, and how well they understood the return-to-duty process.
Executive Summary
A single DOT violation puts a CDL driver into a process most of them have never been through before. In July 2026, we surveyed 1,060 current and former U.S. Commercial Driver’s License holders across the US, all of whom completed the DOT SAP return-to-duty process, to find out what that process really looks like.
The clearest finding: 67.9% of drivers started the process understanding only some of it, or none at all, including 29.2% who had no idea what it involved. The SAP process also is expensive in ways drivers don’t expect: the evaluation fee itself is only a small part of the bill, and the real cost is lost income, with 69.8% of drivers losing more than $3,000 while off the road and 61.3% going into debt to cover it.
Time off the road adds to the toll: 57.5% of drivers were off the road for at least a month, and 8.5% never returned to CDL work. Most drivers (35.8%) find their SAP provider through an online search like Google, and about 4 in 10 say they’d pick a different provider if they had to do it again.
The rest of this report breaks down what drivers told us about the violation that started the process, what it cost them, how their employer reacted, and what they wish they’d known before they started.
Who We Surveyed
All 1,060 respondents are current or former U.S. CDL holders who have personally been through the DOT SAP return-to-duty process. They come from all fifty states and Washington, DC. 67.9% currently hold a CDL, and 32.1% held one previously but no longer do.
Texas had the most respondents (18.9%), followed by Florida (7.5%), Ohio (6.6%), and California, Louisiana, Maryland, and Michigan (4.7% each).
Most respondents went through the process recently. 30.2% did so in the past 12 months, and another 44.3% did so one to two years ago. Only 25.5% went through it three to five years ago.
From Violation to Evaluation: How the Process Starts
Failing or refusing a random drug and alcohol test is the most common reason drivers end up in the SAP process. 43.4% of violations came from a random test, ahead of pre-employment testing (18.9%) and post-accident testing (14.2%). Another 6.6% of drivers refused a test outright, which also counts as a violation.
Marijuana or THC was involved in almost half of all violations (49.1%), by far the most common substance. Alcohol was next (15.1%), followed by amphetamines or methamphetamine (10.4%) and cocaine (9.4%).
Once a violation happens, the process usually moves fast. 24.5% of drivers had their first SAP evaluation within 8 to 14 days of the violation, and 49.1% were seen within two weeks. Still, 21.7% waited 15 to 30 days, and 12.3% waited 31 to 60 days for that first appointment.
What it means for drivers: If you’re in this process because of a random test, you’re not alone. Most drivers didn’t have a long history of substance issues before this. They received an unexpected test result and had to figure out an unfamiliar process fast, just like you.
2 out of 3 Drivers Didn’t Know What to Expect
Before starting the SAP process, only 9.4% of drivers said they understood it completely, and 22.6% said they understood most of it. That leaves 67.9% who understood only some of it (38.7%) or had no idea what it involved (29.2%).
What it means for drivers: If you don’t fully understand what the SAP process involves, you’re not alone. Most drivers felt the same way. Learning what to expect before your first appointment, rather than figuring it out step by step, can save you time and money.
The Real Cost: Fees, Treatment, and Lost Income
The SAP evaluation fee alone isn’t insignificant. 28.3% of drivers paid $451 to $600 just for the evaluation, and 61.3% paid more than $450 overall.
But that’s only one part of the cost. Required education or treatment added more costs: 21.7% paid $200 to $500 for it, 20.8% paid $501 to $1,000, and 14.2% paid $1,001 to $2,000. Only 13.2% needed no education or treatment, and just 3.8% had it covered by insurance or an employer.
Lost income is the biggest expense by far. 21.7% of drivers lost $3,001 to $6,000 in income during the process, another 21.7% lost $6,001 to $10,000, and 15.1% lost $10,001 to $20,000. In total, 69.8% lost more than $3,000, and 47.2% lost more than $6,000. Only 7.5% avoided losing income by staying in a role that didn’t require safety-sensitive driving.
Facing those combined costs, most drivers didn’t pay the full amount themselves. 25.5% put some of it on a credit card, 14.2% borrowed from family or friends, 13.2% used a payment plan through their provider, and 8.5% took out a personal loan. In total, 61.3% went into some form of debt to get through the process. Only 31.1% paid entirely out of pocket, and 7.5% had it fully covered by an employer or union.
What it means for drivers: Don’t budget for the evaluation fee alone. Ask upfront about the full cost, including treatment, and calculate the income you’ll likely lose while you’re off the road. Ask your SAP provider about payment plans before you turn to a credit card or a loan.
Time Off the Road
For most drivers, the SAP process isn’t a quick pause in their work. 28.3% were off the road for one to two months, and 19.8% were off for three to six months. In total, 57.5% were off the road for at least a month, and 9.4% were off for more than six months. Another 8.5% never returned to CDL work at all.
What it means for drivers: Plan for the process to take longer than a few weeks. Most drivers in this survey were off the road for a month or more, so it’s worth preparing financially and personally for a longer timeline than you might expect.
How Employers Responded, and What Happened Next
Employer response was mostly supportive, but far from universal. 15.1% of drivers indicated their employer was very supportive and 28.3% called them somewhat supportive, for a combined 43.4%. On the other side, 21.7% found their employer neutral, 19.8% unsupportive, and 2.8% said their employer retaliated against them, including firing them or pressuring them to quit. Another 12.3% weren’t employed at the time.
What happens after the process often means starting over. Only 30.2% of drivers went back to their previous employer. 37.7% moved to a new employer in the same industry, 7.5% moved to a different industry, 9.4% became self-employed or independent contractors, and 15.1% didn’t return to CDL work at all.
What it means for drivers: Don’t assume your old job will be waiting for you. Most drivers in this survey ended up with a new employer, and some left CDL work entirely. If you sense your employer may not be supportive, know your rights around retaliation and start exploring other options early.
Finding a SAP Provider, and Whether Drivers Would Choose the Same Provider Again
Online search is how most drivers find a SAP provider. 35.8% found theirs through Google or another search engine, ahead of an employer referral (20.8%), a coworker or friend (13.2%), or a referral from a treatment center or counselor (10.4%). Only 8.5% came through a union referral, and 3.8% through a lawyer.
Looking back, drivers are split on whether they’d pick the same provider again. 22.6% said they’d definitely choose differently, and 19.8% said probably, for 42.4% combined. On the other side, 17.9% said they’d definitely choose the same provider again and 21.7% said probably not, for 39.6% who’d stick with their provider. The remaining 17.9% aren’t sure.
What it means for drivers: Take the time to compare SAP providers rather than choosing the first search result. Opinions on providers are split almost down the middle, so a little research upfront, checking reviews and asking about pricing, can help you avoid being one of the 42% who’d pick differently in hindsight.
Action Checklist for Drivers Facing the SAP Process
- Ask your SAP provider for a full breakdown of cost and timeline before you start, not just the evaluation fee.
- Budget for lost income, not just the evaluation fee. Time off the road usually costs more than the fee itself.
- Ask if a payment plan is available before assuming you’ll need a credit card or loan.
- Ask your provider to confirm your evaluation date and next steps in writing so you know what to expect and when.
- Know your rights if your employer retaliates, such as firing you or pressuring you to quit, and keep a record of your communications with them.
- Start job searching early if you think you may need to change employers or leave CDL work.
- Compare more than one SAP provider. Check reviews and ask about pricing upfront before choosing.
Final Thoughts
Three things stand out from this research. First, most drivers start the SAP process without understanding what it involves, and that’s a gap SAP providers could easily close by explaining the process clearly upfront. Second, the real financial burden isn’t the evaluation fee. It’s the income drivers lose and the debt they take on to cover it. Third, the process often resets a driver’s job entirely: most don’t go back to their old employer, and a meaningful share leave CDL work for good.
None of this means the SAP process itself needs to change. It points to an opportunity: a large, steady group of drivers is searching for guidance on cost, timeline, and what to expect, and right now, they aren’t finding it. SAP providers that explain this information upfront can reach drivers at the exact moment they need it.
Methodology
Respondents were current or former U.S. CDL holders who have personally completed the DOT SAP return-to-duty process. All respondents were screened to confirm this before taking the survey.
1,060 qualified respondents completed the survey in full, from 50 states and Washington, DC. Fieldwork ran July 27 to 30, 2026. Figures are rounded to one decimal place. Percentages are based on the full 1,060-respondent sample and may not add up to exactly 100% due to rounding.
FAQ
Not well, for most. Only 9.4% said they understood the process completely before starting, and 67.9% understood only some of it or had no idea what it involved.
The evaluation fee alone costs $451 to $600 for the largest group of drivers (28.3%), but that’s rarely the biggest expense. 69.8% of drivers lost more than $3,000 in income during the process, and 61.3% went into debt of some kind, whether a credit card, personal loan, payment plan, or borrowed money, to get through it.
More than half, 57.5%, are off the road for at least a month, and 9.4% are off for more than six months. Another 8.5% never return to CDL work.
Failing or refusing a random test is the leading cause, responsible for 43.4% of violations, and marijuana or THC is the most common substance involved, at 49.1%.
It’s mixed. 43.4% of drivers say their employer was very or somewhat supportive, while 22.6% say their employer was unsupportive or worse, including 2.8% who report retaliation.
Usually not. Only 30.2% go back to their previous employer. The rest move to a new employer, become self-employed, or leave CDL work entirely.
Search is the top channel. 35.8% of drivers find their provider through Google or another search engine, more than any referral source.
It’s close to an even split. 42.4% say they’d probably or definitely choose differently, while 39.6% say they’d probably or definitely stick with the same provider.
