Terrell runs a five-stop day out of a yard in Fort Worth and never leaves Texas. He does not keep a log. His dispatcher told him he is short-haul, and for four years that has been true. Then an inspector asks for his records of duty status for last Tuesday, and Terrell has none, because on Tuesday one delivery sat 156 air miles from the yard and nobody was measuring.
That is how the 150 air mile radius exemption goes wrong. Almost never through some dramatic abuse. Usually through a stop that crept a few miles past the line, or a shift that ran 20 minutes long at the wash bay, or a driver who assumed air miles and road miles were the same thing.
The exemption itself is straightforward, which is part of the problem. Three conditions, all of them checkable before you start the shift. Drivers who understand the three conditions rarely get caught out. Drivers who understand “150 miles, more or less” get caught out constantly.
This covers property-carrying operations under 49 CFR Part 395 in the United States. The rules here were amended in 2020 and have been amended before that, carriers frequently impose stricter policies of their own, and enforcement practice varies. Verify against current FMCSA material and your own safety department before you build a schedule on it.
The short answer
The 150 air-mile short-haul exception, at 49 CFR 395.1(e)(1), lets a CDL driver skip records of duty status entirely if three things are true for that duty day. You operate within a 150 air-mile radius of your normal work reporting location. You return to that same reporting location and are released from work within 14 consecutive hours of coming on duty. And your carrier keeps a time record showing when you reported, when you were released, and your total hours on duty for the day, retained for six months.
An air mile is a nautical mile, so 150 air miles is about 172.6 statute miles measured as a straight line. The exception removes the logging obligation and the 30-minute break requirement. It does not remove the 11-hour driving limit, the 10 hours off duty, or your 60-hour or 70-hour cycle.
The three conditions, stated plainly
Every article about this rule lists the conditions. Fewer explain what each one actually means at 05:00 on a Tuesday, so here they are with the practical version attached.
Condition one, the radius. You must operate within a 150 air-mile radius of the location where you reported for duty that day. Radius means a circle drawn on a map, centred on your reporting location. Every point you reach during the shift has to sit inside that circle. Nothing about the route matters, only how far the furthest point is from the centre.
Condition two, the 14 hours. You must return to the same work reporting location and be released from work within 14 consecutive hours of going on duty. Consecutive is the operative word. It is wall-clock time, exactly like the standard 14-hour window, and lunch does not stop it. If you go on duty at 05:30, you have to be released by 19:30. Not driving by 19:30. Released.
Condition three, the record. Your carrier has to keep time records showing the time you reported for duty, the time you were released, the total hours on duty for the day, and, for drivers used for the first time or only intermittently, the total time on duty for the preceding seven days. Those records are kept for six months. This is a carrier obligation on paper, but you are the one standing at the window when an officer asks for them.
Miss any one of the three and you are outside the exception for that day.
Air miles are nautical miles, and that is where people go wrong
An air mile is a nautical mile. One nautical mile is 1.15078 statute miles, the miles on your odometer and your road atlas. So the circle is bigger than most drivers assume, and the number of people who think 150 air miles equals 150 road miles is much larger than it should be.
| Air miles (nautical) | Statute miles, straight line | Kilometres, straight line |
|---|---|---|
| 25 | 28.8 | 46.3 |
| 50 | 57.5 | 92.6 |
| 75 | 86.3 | 138.9 |
| 100 | 115.1 | 185.2 |
| 125 | 143.8 | 231.5 |
| 150 | 172.6 | 277.8 |
That bottom row is the one to memorise. A 150 air-mile radius reaches 172.6 statute miles from your yard in every direction. If you want the arithmetic for any other figure, multiply air miles by 1.15078 for statute miles, or use a unit converter rather than rounding to 1.15 and losing three miles at the edge, which is exactly where you cannot afford to lose them.
Radius, not route
Here is the part that trips up experienced drivers, and I would put it above the conversion in importance.
The test is straight-line distance from the reporting location to the furthest point you reach. It says nothing about how many miles you drive. Road distance to a given point is always equal to or greater than the straight-line distance, and in hilly or river-crossed country it can be a lot greater.
So a driver can put 340 miles on the odometer, all of it inside the circle, and be perfectly compliant. Another driver can put 190 miles on the odometer and be outside the exception, because a single stop sat 158 air miles out on a road that happened to run straight.
Odometer readings tell you nothing about whether you qualify. Only the map does. Most routing and mapping tools will give you a straight-line or “as the crow flies” distance if you ask for it, and a handful of dispatch systems draw the radius circle for you. If yours does not, ask your safety department to plot it once and hand every driver a printed map with the circle on it. It is a 20-minute job that prevents a category of violation entirely.
What the exemption does not touch
This table is worth keeping somewhere you can find it, because the exemption is narrower than its reputation.
| Requirement | Under the 150 air-mile exception |
|---|---|
| Records of duty status (logs) | Not required for qualifying days |
| Electronic logging device | Not required for qualifying days |
| 30-minute break after 8 driving hours | Does not apply |
| 11-hour driving limit | Still applies |
| 14-hour on-duty limit | Still applies, and doubles as the release deadline |
| 10 consecutive hours off duty | Still applies |
| 60 hours in 7 days / 70 hours in 8 days | Still applies |
| 34-hour restart | Still available, unchanged |
| Carrier time records | Required, kept 6 months |
| CDL, medical certificate, drug and alcohol programme | Unchanged |
| Vehicle inspection reports | Unchanged |
The cycle row surprises people every time. Short-haul drivers accumulate on-duty hours just as fast as anyone else, and a local outfit running six 13-hour days will hit 70 hours before the week is out. The exemption does not create hours, it only removes paperwork. If you are running heavy weeks, model them properly with the HOS Recap Calculator so you know which day the cycle stops you, and check with the 34-hour restart tool whether a weekend actually gives the hours back. Both run in the browser, and neither one sends your schedule anywhere.
The 30-minute break question
Under the current rule, drivers operating under either short-haul exception in 395.1(e) are not subject to the 30-minute break requirement in 395.3. That is a genuine benefit and it is one of the reasons local fleets like the exemption.
I would attach a caveat, though, and it is not a trivial one. The break exemption applies on days you actually qualify. Bust the radius at 15:00 and you have been driving all day without the break that you now, retrospectively, needed. Whether an officer treats that as a break violation on top of the missing log is a fact-specific question, and it is exactly the sort of thing worth asking your safety department about before it happens rather than after. The mechanics of the break itself, including what counts and when it is due, are covered in the 30-minute break guide.
Do you need an ELD?
Short version: a driver operating under 395.1(e) and not preparing records of duty status is not required to use an electronic logging device for those operations.
Longer version, because there is a second rule sitting behind it. Under 49 CFR 395.8, a driver who is required to prepare records of duty status on not more than 8 days in any 30-day period may use paper logs for those days rather than an ELD. So an otherwise short-haul driver who busts the exemption occasionally can fill out a paper log for those days and stay ELD-free.
Count carefully. It is 8 days in any rolling 30-day period, not 8 days per calendar month. If you overran on the 28th, 29th and 30th of last month, those days are still in the window on the 20th of this one. Day nine flips your operation into ELD territory, and that is a conversation with your carrier, not a form you fill out.
Two things I would flag. First, plenty of carriers fit ELDs to short-haul trucks anyway, for payroll, dispatch visibility or insurance reasons, and once the unit is in the truck you will be using it whatever the regulation permits. Second, ELD rules have been amended before and FMCSA has floated further changes. Do not treat any threshold in this article as permanent. Check the current text.
Losing it: Terrell’s Tuesday, worked through
Back to Terrell, who reports to the Fort Worth yard at 05:30 and runs a four-stop day. Suppose the straight-line distances from the yard to his stops are 62, 118, 147 and 156 air miles.
The first three sit inside the circle. The fourth does not. 156 air miles is 179.5 statute miles from the yard, which is 6.9 statute miles past the 172.6-mile edge. That single stop puts the entire duty day outside the exception, and this is the piece people misread: the exception is evaluated per duty day, not per stop. He does not lose the exception “from the moment he crossed the line”. He loses it for Tuesday.
What Terrell now owes is a complete record of duty status for Tuesday, covering all of it, from 05:30 to release. Line 1, 2, 3 and 4 for the whole day. If the truck has no ELD and Terrell has been on paper for fewer than eight days in the last 30, a paper log covers it.
Now the second failure mode, which is more common and easier to fix. Say every stop had been inside the circle, but the last customer held him at the dock, he got back to the yard at 19:20, and by the time he had fuelled, done his post-trip and handed in paperwork he was released at 19:45. On duty 05:30, released 19:45, elapsed 14 hours 15 minutes. He missed the release deadline by 15 minutes and lost the exception for Tuesday just as thoroughly as if he had driven to Oklahoma.
Fifteen minutes. That is the whole margin, and it is why the release time, not the return time, is the number that matters. Dispatch tends to think about when the truck rolls back through the gate. The regulation cares about when you are released from work. The gap between those two moments is where short-haul days die, and it is normally spent on a fuel island or a wash rack. The mechanics of the 14 hours running on wall-clock time are the same as they are for over-the-road drivers, which the 14-hour driving window guide covers in more depth.
For the week, Terrell’s cycle is unaffected by any of this. He accrued 14 hours 15 minutes of on-duty time on Tuesday regardless of which paperwork rule applied, and it counts against his 70 like any other day. Run the week in the 34-Hour Restart Calculator if you want to see where that leaves Friday.
Six things to check before the shift starts
- Confirm your work reporting location for today. If your carrier runs more than one yard, or you were reassigned, the circle moves with the reporting location and yesterday’s map is wrong.
- Identify the furthest stop on the manifest and check its straight-line distance from that reporting location. Not road miles. Straight line.
- Compare it to 172.6 statute miles, not 150. If it is inside 165 statute miles you have real margin. Between 165 and 172, plot it properly rather than eyeballing.
- Write down your on-duty time and add 14 hours. That is your release deadline, and it belongs on the same piece of paper as the manifest.
- Decide the fallback now. If the day looks like it might overrun, carry a blank paper log or know how to switch your ELD out of exempt status. Deciding at 19:15 is too late.
- Confirm the carrier is actually keeping the time records. Ask once, in writing. If the records do not exist, the exception does not protect you no matter how compliant your driving was.
Step five is the one experienced drivers skip and then regret. A blank paper log in the door pocket costs nothing and turns a violation into an inconvenience.
CDL and non-CDL short-haul, and why old articles disagree
If you search this topic you will find articles quoting 100 air miles and 12 hours. They are not wrong about history, they are just out of date.
Before the hours-of-service changes that took effect in late September 2020, the CDL short-haul exception in 395.1(e)(1) used a 100 air-mile radius and a 12-hour limit. The non-CDL short-haul provision in 395.1(e)(2) already used 150 air miles. The 2020 rule brought the CDL exception up to a 150 air-mile radius and extended the 12 hours to 14.
The two provisions are still not identical. The non-CDL short-haul exception in 395.1(e)(2) allows the on-duty period to extend to 16 hours on two days in any period of seven consecutive days, and it carries its own driving-time conditions. If you drive a vehicle that does not require a CDL, read 395.1(e)(2) rather than assuming the CDL version applies to you, because the differences are not cosmetic.
The date matters for another reason. If your carrier’s driver handbook still says 100 air miles, the handbook was written before September 2020 and probably has other stale content in it. Worth raising.
Do not confuse this with the 16-hour short-haul exception
There is a separate provision at 49 CFR 395.1(o) that lets a property-carrying driver extend the 14-hour window to 16 hours once every seven consecutive days. It is frequently called “the short-haul exception” in conversation, which causes real confusion.
They are different rules doing different jobs. The 150 air-mile exception in 395.1(e) removes your logging obligation. The 16-hour provision in 395.1(o) extends your on-duty window by two hours but does not remove any paperwork and does not extend the 11-hour driving limit. To use 395.1(o) the driver must have started and returned to the same work reporting location for the previous five duty tours, must return to that location on the day in question, and must be released within 16 consecutive hours.
If a dispatcher tells you that you “have the 16-hour”, ask which regulation they mean. The answer changes what you have to write down.
What people miss
The recurring failures are boringly consistent, which is good news, because boring problems have boring fixes.
Measuring in road miles. Covered above, still the number one cause. A driver looks at 300 miles on the trip odometer and panics unnecessarily, or looks at 140 miles and relaxes when a single stop sat 160 air miles out.
Treating the reporting location as fixed. Drivers who normally report to one yard and occasionally start at another keep using the old circle. The circle is drawn from wherever you reported that day.
Release time drift. The 14 hours is measured to release from work, and post-trip, fuelling, washing, paperwork and waiting for a supervisor all sit inside it. A yard that routinely releases people at 14 hours and 10 minutes is running an exemption it does not have.
Records that do not exist. The exception depends on the carrier keeping time records for six months. I have seen the assumption that a payroll timesheet automatically satisfies this, and sometimes it does, but only if it shows report time, release time and total on-duty hours. A timesheet showing only total hours paid does not.
Silent day counting. Nobody in the fleet tracks how many days each driver has filed a paper log in the last 30. Then a driver quietly passes eight and the operation is out of compliance without a single person noticing. That is a spreadsheet job, and the days between dates calculator is a reasonable stopgap if you are checking a single driver’s rolling window by hand.
Assuming the exemption covers the 11 and the 10. It does not, it has never claimed to, and an officer who finds a short-haul driver 12 hours into a driving day will write it up.
A short word on authority
Nothing here is legal advice. Part 395 has been amended more than once, guidance is issued and withdrawn, some states apply intrastate variations to short-haul operations that differ from the federal rule, and penalty amounts and violation scoring are outside what any article should assert with confidence. Read the current text of 49 CFR 395.1(e) and 395.8 through FMCSA, ask your safety department how your carrier applies them, and treat this page as background rather than a ruling.
Frequently asked questions
How many road miles is 150 air miles?
An air mile is a nautical mile, which is about 1.15 statute miles, so a 150 air-mile radius reaches roughly 172.6 statute miles in a straight line from your reporting location. That is the radius, not the distance you drive. Road distance to the same point is always longer because roads bend, so plenty of drivers cover 350 road miles inside the circle without ever leaving it.
Do I need an ELD if I stay within 150 air miles?
If you genuinely qualify for the short-haul exception in 49 CFR 395.1(e) and therefore do not prepare records of duty status, an ELD is not required for those operations. Your carrier still has to keep time records. Many fleets install ELDs anyway for payroll and dispatch reasons. Check current FMCSA guidance and your carrier policy before assuming you are exempt.
What happens if I go over 150 air miles for one day?
You lose the exception for that day only, not permanently. For that duty day you need a complete record of duty status covering the whole day, not just the part outside the radius. The day also counts toward the limit on how often you can use paper logs before an electronic logging device becomes required for your operation.
Does the 150 air-mile exemption exempt me from the 11-hour driving limit?
No. The short-haul exception relieves you of the record of duty status requirement and, under current rules, the 30-minute break. It does not touch the 11-hour driving limit, the 10 consecutive hours off duty, or the 60-hour and 70-hour cycle limits. Those still apply in full, and inspectors still check them against the carrier’s time records.
How many days a month can I exceed the short-haul exemption before I need an ELD?
Under 49 CFR 395.8, a driver who is required to prepare records of duty status on not more than 8 days in any 30-day period may use paper logs for those days instead of an electronic logging device. Hit day nine within a rolling 30 days and an ELD becomes required. Verify the current threshold with FMCSA, since ELD rules have been amended before.
Is the 150 air-mile radius measured from my home or from my terminal?
From your normal work reporting location, which is the place you report to for that duty day. It is not your home unless your home is where you report. If your carrier assigns you to a different yard on a given day, the circle moves to that yard for that day. Get the reporting location confirmed in writing if it changes often.
What to do with this
Draw the circle once and put it where everyone can see it. A printed map of your yard with a 172.6-mile radius on it does more for compliance than any amount of policy language, because it converts an abstract rule into a shape a driver can point at.
Then fix the release time. Most short-haul violations I would expect a fleet to accumulate are not radius problems at all, they are 14-hour-and-change days caused by a wash bay queue or a supervisor who was in a meeting. That is a scheduling problem with a scheduling fix.
And keep a blank paper log in every truck. The exemption is not fragile, but it does fail occasionally, and the difference between a bad day and a violation is usually just whether you had something to write on.
