It is a Thursday in February in Fort Lauderdale. You run a 15-truck commercial landscaping and hardscape business across Broward, Miami-Dade and Palm Beach counties. Your trucks are 12 F-250 Super Duty service trucks with trailers and 3 F-450 dump trucks. You have been operating under the short-haul 100-air-mile exemption since you registered your USDOT number three years ago. No ELDs in the fleet. Drivers sign a simple daily time sheet. Your logs have never been audited.

In February your senior crew lead, Miguel, attends a 1-day ICPI paver certification course in Orlando — 212 air miles from your Davie yard. He drives an F-250 up and back the same day. Three days later a driver in a different F-250 is stopped at a DOT inspection site on I-95 south of Stuart. The officer pulls the company's supporting documents for random review. Among them is Miguel's expense reimbursement for the Orlando trip. The driver currently in front of the officer has no ELD. The officer notes the short-haul exemption exception and initiates a compliance review. The review finds Miguel's trip put the company out of short-haul exemption for that day. Retroactive 12-month ELD compliance review triggered. No records of HOS compliance available. Civil penalties totaling $14,800 levied.

This is the short-haul exemption trap. The rule itself is clear; most SMB trades fleet owners read only the headline ("under 100 miles = exempt") and miss the conditions underneath. Here is the full rule, where it breaks in practice, and the operational rhythm that keeps an SMB trades fleet honestly inside it.

The ELD mandate in one paragraph

The Electronic Logging Device (ELD) mandate under 49 CFR Part 395 requires most commercial motor vehicle drivers subject to Hours of Service rules to use an FMCSA-registered ELD to record duty status, driving time, and engine data. The mandate took full effect in December 2019 (after a 2-year phase-in from the original December 2017 rule). An ELD connects to the vehicle's engine control module, captures ignition, movement and location every 60 seconds of driving, and produces a standard output that a DOT officer can read at roadside.

The four Hours-of-Service limits every CMV driver works within

Under FMCSA Hours of Service rules, a property-carrying CMV driver is subject to:

  1. 11-hour driving limit — maximum 11 hours of driving after 10 consecutive hours off duty.
  2. 14-hour on-duty limit — driving is not permitted beyond the 14th consecutive hour after coming on duty. Off-duty time inside the 14-hour window does not extend it.
  3. 30-minute break — after 8 cumulative hours of driving, a 30-minute break is required (may be off-duty, sleeper berth, or on-duty not driving).
  4. 60/70-hour limit — 60 hours in 7 consecutive days, or 70 hours in 8 consecutive days (carrier picks the cycle). A 34-hour off-duty period resets the cycle.

Violate any of these and the driver and carrier both face penalties. Falsifying logs is a significantly worse offense than simple overdrive.

The short-haul 100-air-mile exemption — the real rule

The short-haul exemption under 49 CFR 395.1(e)(1) exempts a driver from ELD use and from daily log-keeping if, on that particular day, all of the following are true:

  • The driver operates within a 150-air-mile radius of the normal work reporting location (expanded from 100 in 2020; most SMB trades fleets are well inside this).
  • The driver returns to the work reporting location and is released from duty within 14 consecutive hours of coming on duty.
  • The driver has at least 10 consecutive hours off duty between shifts.
  • The driver does not drive more than 11 hours within the 14-hour window.
  • The carrier maintains time records showing start time, end time and total hours on duty for each driver for each day, retained 6 months.

The exemption applies per day, per driver. A driver on the exemption Monday, Tuesday and Wednesday, then out of exemption Thursday (went 180 air miles) is exempt 3 days and non-exempt 1 day. On Thursday that driver must be on ELD with full logs.

Where the exemption quietly breaks for SMB trades fleets

  1. Certification classes, trade shows, supplier visits out of area. The Miguel scenario above. A 220-mile round trip to Orlando blows the exemption for the day.
  2. Emergency jobs in a neighboring market. An HVAC contractor 90 miles from a customer's sister location in another metro. Round trip puts the driver outside the 150 mile radius.
  3. Deliveries from distant suppliers. An electrical contractor picks up a switchgear from a distributor 175 miles away. Day out of exemption.
  4. Vehicle swaps and recovery runs. A truck breaks down 160 miles away. Sending a driver to retrieve it puts that driver out of exemption that day.
  5. The driver who does paperwork 30 minutes on-duty at night. Not a short-haul issue, but a 14-hour window issue. The on-duty clock starts when the driver begins any work, including equipment checks or customer calls. Drivers who answer a customer call at 6:30 AM and begin driving at 7:00 AM need to be off-duty driving by 8:30 PM that night.

For a 15-20 truck trades fleet running mostly intrastate within a single metro, the short-haul exemption is practical 90-95% of the time. The 5-10% exception cases are where the compliance disaster sits. The fix is not "never go more than 150 miles." The fix is knowing on which days you are out of exemption and having ELD-and-log coverage for those days.

The supporting documents rule — why DOT officers read your receipts

Under 49 CFR 395.11, a motor carrier must retain supporting documents that corroborate HOS records:

  • Bills of lading, itineraries, schedules.
  • Dispatch records, trip records.
  • Toll receipts, fuel receipts, meal receipts that show time and location.
  • Communications to and from the driver.
  • Payroll records, expense reimbursements.

An audit compares supporting documents to logs. A fuel receipt in Georgia when the log shows the driver in Alabama triggers deeper review. Expense reimbursement showing out-of-area travel while daily logs claim exemption triggers review. This is how Miguel's expense reimbursement for the Orlando trip burned the company — the document showed he was out of area on a day the company had no ELD record of.

ELD costs — and the buy-or-rent question for a 20-truck trades fleet

ELD services are a recurring operational cost, not a one-time purchase. Typical 2026 pricing for FMCSA-registered ELDs on short-haul-majority trades fleets:

  • Hardware — most providers now give the ELD device free or as a nominal rental included in the monthly fee. Older purchase-outright options run $150-$350 per vehicle.
  • Monthly subscription — $18-$45 per vehicle per month, including software, driver app, DOT-compliant logs, roadside inspection output.
  • IFTA and GPS bundles — add $5-$15 per vehicle per month each. Most trades fleets want GPS regardless for theft recovery and dispatch.

Total: $35-$75 per vehicle per month for ELD + IFTA + GPS fully bundled. For 20 trucks, $8,400-$18,000 annually. Significantly less than a single HOS civil penalty event.

The ELD market is crowded. Samsara, Motive, Verizon Connect, Geotab, Teletrac Navman, Omnitracs, GPS Insight, Azuga, EROAD all hold meaningful US SMB share. Feature sets are now similar enough that price and contract flexibility usually win. Read the cancellation terms before signing — some providers use 36-month contracts that lock you in long past the real decision point.

The practical short-haul exemption operating rule for a 20-truck trades fleet

  1. Assume short-haul by default for every driver every day. Maintain the 6-month time record (start, end, total hours on duty) as required by 395.1(e)(1).
  2. Identify and flag any day out of exemption. Supplier pickups over 150 miles, out-of-metro customer visits, certification classes, vehicle swaps. Any trip over 150 air miles from the normal reporting location.
  3. For flagged days, require ELD coverage. Either a permanent ELD installed on every vehicle (operationally simplest), or a portable ELD unit assigned to the out-of-exemption trip (cheaper if the flagged days are rare).
  4. Maintain supporting documents honestly. Fuel receipts, toll records, expense reimbursements — these will surface in audit. Matching them to logs is the carrier's responsibility.
  5. Brief drivers on the 14-hour on-duty rule. Not just driving time — on-duty time. Answering the customer phone at 6 AM starts the clock even if the truck rolls at 7 AM.
  6. Document the exemption decision in your policy manual. If an audit finds your short-haul reliance is undocumented, you lose the benefit of the doubt.

Why we care

Mekavo Fleet tracks driver medical card expiry, CDL expiry, training records and trip-day history alongside vehicle documents. For a trades fleet running short-haul exemption 90% of the time, we make the 10% of out-of-exemption days visible before they become a roadside compliance failure. We do not replace an ELD — ELDs are specialized, DOT-registered devices. We replace the mess of spreadsheets and shared calendars that let a driver's certification-class day slip into next month's civil penalty.
