Intro: Start with job functions, not course names
Many employers buy compliance training the same way they buy office supplies: a vendor email arrives, a course name sounds familiar, and someone purchases seats “just in case.” That approach creates two common problems:
- You buy the wrong course for the wrong people.
- You still miss a training requirement tied to a specific job function.
A better approach is to map what people do (their regulated functions), then match training to those functions. That is especially important when one person wears multiple hats (owner + supervisor + DER + dispatch/admin + hazmat shipping support).
This guide gives you a practical employer checklist to determine:
- who needs training,
- what training is legally required vs recommended,
- when training is due,
- what records to keep, and
- how to choose a provider that will not create documentation headaches later.

Start Here: Don’t Buy Training by Course Name — Buy by Job Function
Course names are marketing labels. Regulations generally care about functions, not vendor naming.
Examples:
- A regulation may require supervisor training for a specific purpose, but not require a course with a particular brand name.
- Your company may need a DER role, but the rule does not say you must buy a course titled exactly “DER Training.”
- Hazmat training is not one course for “drivers only.” It depends on whether employees perform hazmat functions.
When you buy by course name alone, you may end up with:
- duplicate training,
- gaps in function-specific coverage,
- weak records that do not map to duties,
- confusion when auditors or customers ask for proof.
The fix is a simple role/function matrix (included below) that you can use before you purchase anything.
The 5-Step Employer Decision Process
1) Define what your company actually does
Start with operations, not org charts.
Ask:
- Do we operate CDL-required vehicles?
- Do we have supervisors who may need to make reasonable suspicion determinations for CDL drivers?
- Who handles our DOT drug and alcohol testing program decisions and test-result communications?
- Do we offer, prepare, load, transport, or document hazardous materials shipments?
- Do we rely on customer sites, shippers, or insurers that impose extra training expectations?
A small carrier may answer “yes” to all of the above with only 5 people on staff.
2) Identify who performs regulated functions
Titles are not enough. List the actual people who perform each function.
Examples of function-based mapping:
- Operations manager who supervises CDL drivers = may need reasonable suspicion supervisor training.
- Owner handling drug/alcohol program decisions = may be acting as DER.
- Warehouse lead preparing shipping papers = hazmat employee (if hazmat shipments are involved).
- Dispatcher entering hazmat shipment details and coordinating offers = may perform covered hazmat functions depending on duties.
3) Match the rule to the function
This is where you separate what is legally required from what is simply helpful.
Examples:
- FMCSA reasonable suspicion supervisor training (49 CFR 382.603): applies to persons designated to supervise drivers for purposes of determining reasonable suspicion under the FMCSA testing rule.
- DER role (49 CFR Part 40 context): employers need DER coverage in practice for DOT drug/alcohol program administration; Part 40 defines the DER role and limits service agents from acting as the DER.
- Hazmat training (49 CFR 172.704): applies to hazmat employees based on the functions they perform, not just driving.
4) Determine timing (initial, role change, recurrent, refresher)
Buyers often make mistakes here because they confuse:
- legal deadlines,
- internal onboarding timelines,
- customer expectations, and
- best-practice refreshers.
For example:
- FMCSA reasonable suspicion supervisor training has a required initial content/time requirement, and the regulation states recurrent training is not required under 49 CFR 382.603.
- Hazmat training under 49 CFR 172.704 includes specific timing for new employees/changed functions and recurrent training intervals.
5) Decide what records you will retain (before you choose a vendor)
Do this upfront so you can buy a provider that supports your recordkeeping process.
At minimum, decide:
- where training records live,
- who can retrieve them during an audit/inspection,
- how you track due dates by role,
- what employer-created documentation is retained in addition to certificates.
Role-by-Role Training Matrix (Employer Checklist)
Use this as a working matrix before purchasing training. Customize it to your operation.
| Role / Function | Common Trigger | Usually Legally Required? | Timing Questions | Recordkeeping Notes |
|---|---|---|---|---|
| CDL driver supervisor (reasonable suspicion decision-maker) | Supervises CDL drivers and may order testing based on reasonable suspicion | Yes under FMCSA if designated to supervise drivers for this purpose (49 CFR 382.603) | Before relying on that person to make determinations; refresher timing is employer decision/best practice | Keep proof of training completion and your internal role assignment list |
| DER (Designated Employer Representative) | Receives results, makes testing/evaluation process decisions, coordinates program actions | DER function exists in Part 40 framework; course naming is not prescribed | Train before assigning DER responsibilities; refresh when program changes or role changes | Keep DER designation, program procedures, training records, and contact coverage plan |
| Hazmat employee (shipping/packaging/marking/labeling/papers/loading/unloading) | Performs a function affecting hazmat transportation safety | Yes if employee meets hazmat employee definition and performs covered functions (49 CFR 172.704) | New hire/role change timing, supervised-work window, recurrent cycle, security-plan triggers | Hazmat records must meet 172.704(d) content and retention rules |
| Owner / admin / dispatcher (multi-hat) | Handles supervision, DER duties, or hazmat documentation | Depends on actual functions performed | Check each function separately; one person may need multiple trainings | Keep one matrix showing all functions to prevent gaps |
| Non-supervisory office staff | No regulatory function, but handles scheduling/admin support only | Often no specific DOT training requirement for that role alone | Customer/contract or internal policy may still drive training | Separate “required” vs “recommended” in records |
CDL Driver Supervisors (Reasonable Suspicion)
What is required under 49 CFR 382.603?
For FMCSA-covered employers, persons designated to supervise drivers must receive:
- at least 60 minutes on alcohol misuse, and
- at least an additional 60 minutes on controlled substances use
for the purpose of determining whether reasonable suspicion exists to require testing under the FMCSA rule.
The training must cover observable indicators (physical, behavioral, speech, and performance).
Is recurrent training required?
Under 49 CFR 382.603, the regulation states that recurrent training for supervisory personnel is not required.
That is an important buyer decision point:
- Legally required: initial FMCSA-compliant supervisor training.
- Commonly recommended: refresher training after long gaps, policy changes, incidents, or supervisor turnover.
If a vendor markets “annual recertification” as mandatory, ask them to identify the exact FMCSA citation.
Who counts as a supervisor here?
Think functionally:
- fleet manager,
- terminal manager,
- operations manager,
- shift supervisor,
- owner-operator employer supervising drivers,
- any person who may need to make the reasonable suspicion call.
If they might make the determination, train them.
DER (Designated Employer Representative)
What the DER role means (plain English)
A DER is the employer’s authorized employee who can receive test results/communications and make required decisions in the DOT drug and alcohol testing process, including taking immediate action to remove employees (or cause removal) from safety-sensitive functions when required.
Is a “DER course” legally required by name?
This is where buyers get confused.
- The regulations define the DER role and responsibilities in 49 CFR Part 40.
- The regulations do not require a course with a specific product name like “DER Certification” by title.
However, in practice, employers often use DER training to prepare the person assigned to perform the role correctly. That is usually a smart decision because DER responsibilities involve time-sensitive decisions, documentation, and coordination with service agents.
Can a C/TPA or consultant be your DER?
Part 40 is clear that service agents cannot act as DERs (see the DER definition in 49 CFR 40.3 and the employer responsibility rule in 49 CFR 40.15(d)).
Practical takeaway for buyers:
- Your C/TPA can support your program.
- Your C/TPA cannot be the DER.
- The employer remains responsible for compliance even when using service agents.
Small-employer reality: can the owner be the DER?
Often, yes in practice, if the owner is the employer/employee acting in that role. DOT ODAPC guidance addresses this scenario. The key issue is that the DER must be an actual employer employee and must be able to exercise authority required by the role.
Hazmat Employees (If Applicable)
Do not assume hazmat training is “for drivers only”
If your business offers or transports hazardous materials, hazmat training applicability can extend to:
- shipping/receiving personnel,
- warehouse pack-out staff,
- employees selecting packaging,
- staff preparing shipping papers,
- loaders/unloaders,
- drivers performing hazmat functions,
- dispatch/admin/logistics staff performing covered documentation or offering functions.
What matters most: function-specific coverage
49 CFR 172.704 requires training components and function-specific content tied to what the employee actually does.
If you only buy a generic “hazmat awareness” course for employees who prepare shipping papers or make packaging/labeling decisions, you may still have a gap.
For a deeper breakdown, see Who Needs Hazmat Training Under 49 CFR 172.704? A Practical Employer Guide.
Owners, Admin, Dispatch, and Multi-Hat Teams
This is the most common scenario in small and midsize operations.
One person may be:
- supervising CDL drivers,
- acting as DER,
- handling vendor coordination with the C/TPA,
- preparing or reviewing hazmat paperwork,
- assigning employee training.
That does not mean one course covers all responsibilities.
It means one person may need a bundle of role-specific training and procedures. Your matrix should be person-based and function-based, not title-based.
Required vs Recommended Training (Trust-Builder Table)
Use this framework when evaluating vendor recommendations.
| Category | What it means | Example | How to buy it |
|---|---|---|---|
| Required by regulation | Directly tied to a rule/citation for your function | FMCSA reasonable suspicion supervisor training under 49 CFR 382.603 | Buy only for designated supervisors; document applicability |
| Required by customer/contract/site/insurer | Not necessarily in the DOT citation, but imposed by business relationship | Customer site requires annual refresher or site-specific orientation | Keep requirement source (contract/site rules) in your records |
| Recommended / best practice | Improves readiness but not necessarily required by citation | DER refresher after policy overhaul; supervisor refresher every few years | Buy intentionally; label as refresher in your matrix |
| Company policy training | Internal standard you choose for consistency or risk management | Annual onboarding refresh for dispatch/admin on internal procedures | Useful if documented clearly and separated from legal requirements |
Timing Questions Buyers Ask (and how to think about them)
“Do employees need training before their start date?”
Usually frame this as: before they perform the regulated function unsupervised. Some rules allow a limited completion window with supervision (notably hazmat under 49 CFR 172.704). Others are best treated as pre-assignment requirements.
“Are there grace periods?”
Sometimes, but do not assume. Use the specific rule.
Hazmat training has a 90-day completion window (with supervised performance conditions) for new employees or changed functions under 49 CFR 172.704(c). That does not mean every DOT-related training has the same timing structure.
“Is this one-time or recurring?”
It depends on the training and the rule.
- Reasonable suspicion supervisor training (FMCSA 382.603): initial required; recurrent not required by that section.
- Hazmat training (172.704): recurrent training required at least every 3 years, with additional triggers for changes and certain security-plan updates.
- DER training: treat as role-readiness training and refresh as needed based on program complexity, turnover, and changes.
“What if someone changes roles?”
Re-run the function matrix. New duties can create new training obligations.
Questions to Ask Internally Before Buying Training (Checklist)
- Which employees are designated to supervise CDL drivers for reasonable suspicion decisions?
- Who is our DER, and who is backup DER coverage?
- Do any employees perform hazmat shipping/packaging/marking/labeling/shipping-paper/loading functions?
- Which roles changed in the last 12 months?
- Which trainings are required by regulation vs customer contract vs policy?
- Where are our records stored today, and can we retrieve them quickly?
- Do we need English + Spanish delivery?
- Do we need team seat management and dashboards?
- Do we need vendor help mapping roles to courses?
How to Choose a Training Provider (Mini Version)
Before buying, ask whether the provider gives you these basics:
1) CFR-aligned scope
Can they explain the training in terms of the applicable regulation and role/function, not just a course title?
2) Audience clarity
Does the course clearly identify who it is for (supervisors, DERs, hazmat shipping staff, drivers, etc.)?
3) Adequate depth and runtime
For regulated training with duration/content expectations, does the provider state what is covered and how long it takes?
4) Certificates and records
Will you get proof of completion and a way to retrieve records later?
5) Documentation support
Do they help you understand what the employer still needs to document internally (designation, matrix, procedures, due dates)?
6) Industry relevance
Is the training built for trucking/logistics/warehouse operations, or is it a generic compliance course with weak operational examples?
For a deeper pre-purchase checklist, see How to Determine What Compliance Training You Need (and How to Choose the Right Provider).
Common Mistakes (and how to avoid them)
Mistake 1: Buying the wrong course for the wrong role
Fix: Start with the role/function matrix and map each person before purchasing.
Mistake 2: Assuming one course covers “all DOT compliance”
Fix: Separate FMCSA drug/alcohol program training, DER role readiness, and hazmat function-specific training.
Mistake 3: Missing supervisor or DER coverage during turnover
Fix: Track role assignments and backup coverage, not just employee names.
Mistake 4: Weak recordkeeping
Fix: Choose a provider with retrievable records and maintain your internal training matrix/due-date tracker.
Mistake 5: Buying based on solicitation pressure
Fix: Ask the vendor to identify the specific role/function and regulation the course addresses.
Soft CTA: Get a role-based training map before you buy
If you are not sure whether your team needs supervisor training, DER training, hazmat training, or a combination, start with a role/function map instead of buying courses one-by-one.

FAQ: DOT / FMCSA Training Requirements by Role
Which employees need DOT training at a trucking company?
Only employees who perform covered/regulatory functions need specific DOT-related training. Start by identifying supervisors (reasonable suspicion), DER responsibilities, and any hazmat functions.
Can one person be an owner, supervisor, and DER?
Yes, in many small businesses one person wears multiple hats. The key is to map each function and ensure the person is trained for each role they actually perform.
Is DER training legally required by regulation?
The regulations define the DER role and responsibilities, but they do not require a course by a specific product name. Employers commonly use DER training to prepare the assigned person to perform the role correctly.
Is reasonable suspicion training annual?
49 CFR 382.603 does not require recurrent supervisor training. Some employers still schedule refreshers as a best practice.
Do dispatchers or office staff need hazmat training?
It depends on duties. If they perform covered hazmat functions (for example, preparing shipping papers or offering hazmat shipments), they may need hazmat training under 49 CFR 172.704.
What records should we keep after training?
Keep certificates, provider records, and your internal role/function matrix that shows why each person received a given training and when retraining is due.
Can a vendor tell me exactly what I am legally required to buy?
A good vendor can help map training options to common roles and regulations, but the employer remains responsible for determining applicability and compliance.
What is the best first step if we are unsure?
Build a simple roster of employees, list what each person does, and map those duties to rules before buying any training.
