A day earns an Overdrive four ways: Off-Duty, Timed, Mileage, and Rule #1. Two more rules, claim logic and co-drivers, tie them together. The first card below is the whole system in about a minute, and everything after it is the same four things explained at length.
Aligned with the Overdrive Rules Training Manual v1.0
The One-Minute Version
The whole system on one screen
Your day runs from lobby call to your own room key. At the end of it you count four things and add them together, and that is the entire system. Everything further down this page is one of these four explained at length, so if you only ever read this card you can still count a day correctly.
1Rest. Did you get 10 hours off before the day started? Under 10 is one Overdrive, and it stays one no matter how far under you were. Your rest clock starts when the room key is in your hand, not when you pulled into the lot.
2Rule #1. One for each toilet clog. It stands on its own and has nothing to do with your miles, your hours, or your sleep.
3Miles or hours, the bigger of the two. Miles: 450 is one, 600 is two, 700 is three. Hours: 10 on the clock is one. You take whichever number is larger and you never add them together.
4The long day, on top of number 3. One more at 12 hours, one at 13, one at 14, one at 15, and one for every hour past 15. These always add, no matter what your miles did.
One day, counted. You slept 8 hours, somebody clogged the toilet, you ran 600 miles, and you were on the clock 12 hours. That is 1 for the short rest, 1 for the clog, 2 for the miles because 600 beats the 10-hour claim of 1, and 1 more for reaching 12 hours. Four things, added up, and the day is a 5.
Two more rules sit behind those four rather than beside them. Claim logic is the part of number 3 about keeping the bigger figure, and co-driver operations is the fact that all of this counts per driver instead of per bus, which is why a second driver brings everybody's number down.
Three things drivers get wrong
Your day does not end at the client. Dropping them off is not the finish line. The day ends when you have your own room key, so the fuel run and the ride out to a hotel that can park a coach are still on the clock.
Miles come off the odometer. Not off a maps estimate. The lines are exact, so 449 miles is nothing and 450 is one.
Midnight does not split your miles. Driving through it changes nothing on its own. Miles only split when the second drive starts on a new calendar day.
Start Here
What an Overdrive actually is
An Overdrive marks a day that pushed past full rest, whether that came from a short night or from long miles. It works as a tally rather than a punishment, so nobody is in trouble for running one up. The number simply shows how hard the day ran.
Overdrive sets a higher bar than the law. DOT, the government's trucking rules, asks whether a day is legal. Overdrive asks whether it's the safest, most-rested way to drive. A day can be fully legal under DOT and still run up Overdrives.

From on duty to off duty
From lobby call to the room key
That middle row does more work than it looks like. Under DOT the 15 hours are a running total of time worked rather than a stretch of the day, so going off duty freezes the count and you pick it back up at the same number. Only 8 straight hours off resets it, and the rule never says you have to take them. Work 8 hours, sit off duty for 7 hours and 59 minutes, then work 7 more, and you finish 23 hours after you started with a worked total of 15 and nothing illegal about it.
The Overdrive clock doesn't freeze. It starts at your first minute on duty and runs until you get 10 hours off, and every hour it shows past 15 is one more Overdrive. So that same stretched day reads 23 hours and counts 13, against the 5 a straight 15-hour day would have cost. The 8 extra are what the long break is paying for.
Both ends of that clock have a name on the road. Your day starts at lobby call, which is when the runner leaves the hotel to carry the drivers over to the venue. Bus call comes later and is the time the coach itself pulls out for the next city, so it doesn't start anything. On a 1 AM lobby call with a 2 AM bus call, you have an hour on the clock before a wheel turns. The other end is the room key. Dropping the client off doesn't end your day, so the ride out to a hotel that can park a coach is still on the clock.
The Gap
Legal and rested are not the same question
One workday from the first minute on duty to the last, measured two ways. DOT passes the whole span, because its 15 hours count only the time you are working and freeze whenever you go off duty. Overdrive starts counting at 10 and never stops.

Nothing on this chart is illegal. A driver who works 8 hours, sits off duty for 7 hours and 59 minutes, then works 7 more has put in 15 hours and finished 23 hours after he started, and DOT has no objection to any of it. His Overdrive clock read 23, so the day cost 13 instead of 5. Overdrive counts the whole span so the long day can be planned differently next time.
The four ways to earn one
Every Overdrive falls into one of four buckets. Count them one at a time, then add them up.
Off-Duty
Rest under 10 hours = 1
Timed
10 through 15 hours = 1 to 5, then +1 every hour
Mileage
450 / 600 / 700 miles = 1 / 2 / 3
Rule #1
A toilet clog = 1, on its own
Two more rules connect them: Claim Logic (keep the bigger of miles vs. the 10-hour Overdrive, never both) and Co-Driver Operations (Overdrives are counted per driver, so a second driver lowers the total).
Count a day's Overdrives
Add four things together:
Off-Duty (0 or 1) + Rule #1 (per clog) + greater of [ Mileage , 10-hr timed ] + 1 for each of 12 / 13 / 14 / 15 h + 1 for every hour past 15
Worked example, 8 hours rest · one clog · 600 miles · a 12-hour day:
+1Off-Duty: rest was under 10 hours
+1Rule #1: one toilet clog
+2Mileage vs. timed: 600 mi = 2 beats the 10-hr claim of 1
+1Long day: hit the 12-hour line
Total for the day5
Worked Example
One day, counted step by step
Room key at 11 PM, lobby call at 7 AM, off the clock at 7 PM, 600 miles on the odometer, and one toilet clog. Here is where each Overdrive lands.

600 miles clears the 450 line and reaches the 600 line, so mileage is 2.
Claim logic
greater of [ mileage 2 , 10-hr timed 1 ] = 2
Those two never add together. You keep the bigger one.
Total for the day5
1 off-duty + 1 Rule #1 + 2 (miles beat the 10-hr claim) + 1 twelve-hour line
Add one more at each of 13, 14, and 15 hours if the day runs that long, then one more for every hour the clock shows past 15, and one more for every additional clog.
The Standard
Why ten hours is the line
Ten hours comes from a weekly cap. DOT lets a driver work only 70 hours in any 8 days, so spreading that across the week, 70 divided by 8, lands you near 8.75 hours a day. That is the fastest pace one driver can keep up indefinitely without running dry.
So 10 hours a day is already the top end. A driver can hold that pace for about a week before hitting the wall and having to stop, and pushing the day longer only burns through the 70 faster.
On-duty hours per day
Days until out of hours
8.75 (sustainable)
Never runs out
10 (the ceiling)
~7 days, then a forced stop
12
~5.8 days
13
~5.4 days
About 449 miles a day, just under the first Mileage Overdrive, is the same steady pace measured in distance instead of hours.
The Math Behind a 13-Hour Day
A 13-hour workday may seem reasonable at first, but the math adds up quickly.
You begin with 70 hours, which is the maximum you can work in any rolling 8-day period. Those hours don't reset. You only get them back as older hours fall off.
If you work 13 hours a day for five consecutive days, here's what happens:
13 × 5 = 65hours worked
70 − 65 = 5hours remaining
By Day 6 you would need another 13-hour day, but you only have 5 hours available. That run can't legally continue until enough hours fall off your 70-hour clock, and that won't happen until Day 9.
To keep the tour moving, the company often has to:
Fly a co-driver out to the bus
Pay the co-driver's daily rate
Cover hotel expenses each night
Fly the co-driver home afterward
If you average 8 hours and 45 minutes per day, you'll never run out of available hours on your 70-hour clock. That means you can legally work 7 days a week, week after week, without exhausting your available hours.
This is why the timed Overdrive threshold should never be set above 10 hours per day.
Once drivers regularly work 11-, 12-, or 13-hour days, they burn through their available hours much faster, forcing downtime or requiring companies to bring in co-drivers just to keep the tour moving.
All seven rules
Filter by category, or read them straight through.
1
Rule #1
Rule #1 NO #2
The bus toilet is for liquid only. If someone goes number two and clogs it, that's one Overdrive on its own.
A tour bus toilet only handles liquid. Put solid waste in it and it can clog and quit working. Then the driver has to stop and deal with it: shut it down, clean it out, or get it serviced. That job costs real time, so it counts as one Overdrive by itself. Miles, hours, and sleep don't factor in.
It sounds like a joke, but it is a real part of the system and it has its own name.
Example
The band's bus is running to the next city around 2 AM. Someone uses the toilet for number two and it clogs. Now, instead of watching the road, the driver is pulling over to work on the tank. That's one Overdrive.
Liquid only in the bus toilet
A clog can mean shutting it down, cleaning, or servicing it
Counts as one Overdrive by itself
Separate from miles, hours, and rest
2
Off-Duty
Off-Duty Overdrives
A driver should get 10 hours of rest in a row. Anything less is one Overdrive.
A driver needs 10 hours off in a row to be rested. The catch is when that clock starts. It doesn't start when the bus parks. It starts when the driver actually has the hotel room key.
Waiting in the lobby isn't rest. The ride to the hotel isn't rest. The clock runs from key in hand until lobby call, which is the time the runner leaves the hotel to carry the drivers over to the venue. If that comes to less than 10 hours, it's one Off-Duty Overdrive.
This one doesn't grow. Two hours short or five hours short, it's still just one. And any work during that window, like sweeping out the bus or checking the engine, counts as work, not rest.
Booking matters here too. If the tour manager books the room for the night before, it's ready the second the bus pulls in, even at 7 AM. Skip that and the driver can be stuck waiting for normal check-in, often 3 PM, which usually costs an Overdrive on its own.
Example
The driver gets the room key at 11 PM. Lobby call is 7 AM. That's 8 hours of rest, two short of 10. The law is fine with it. Overdrive still counts it as one, because a short night makes for a tired driver.
Aim for 10 hours of rest in a row
The clock starts at the room key, not when the bus parks
It ends at lobby call, when the runner pulls out of the hotel
Under 10 hours is one Off-Duty Overdrive, and it never grows
Work during rest counts as work, not rest
3
Timed
Timed Overdrives
One Overdrive at 10 hours, another at 12, then one more for every hour after that. The clock never stops.
The day starts at lobby call, which is the time the runner leaves the hotel to carry the drivers over to the venue, and it ends when the driver has the room key that night. Bus call, the time the coach itself pulls out of the venue for the next city, falls somewhere in between and doesn't start anything. If lobby call is 1 AM and bus call is 2 AM, that hour is already on the clock before a wheel turns. From there, one clock runs, and it keeps running through breaks. Stopping to eat or wait doesn't pause it. It doesn't stop until you get 10 consecutive hours off.
The hours add up in steps (see the chart). You have to actually reach a line to count it. At 11 hours you've only hit the 10-hour mark. The moment it turns 12, that's the next one. Past 15 it gets simpler, because every additional hour the clock shows is one more Overdrive. Two DOT limits still can't be crossed either way: no more than 10 hours of driving, and no more than 15 hours of actual work.
That last part is where Overdrive parts ways with DOT. Under the federal rule for buses, those 15 hours are a running total of time worked rather than a stretch of the day, so the count freezes the minute you go off duty and picks up at the same number when you come back. Only 8 straight hours off resets it, and nothing in the rule ever says you have to take them. That's how a day can run 20 or 24 hours from end to end while your worked total is still sitting at 15 and nothing about it is illegal.
The Overdrive clock doesn't freeze. Take a driver who starts at a 6 AM lobby call, works 8 hours, sits off duty for 7 hours and 59 minutes, then works 7 more and finishes at 5 AM. He worked 15 hours, so DOT has no problem with the day. His Overdrive clock read 23 hours, which is 13 Timed Overdrives instead of the 5 a straight 15-hour day would have cost him. Those extra 8 are what the stretched day is paying for.
Example
A driver has a 6 AM lobby call. Lunch and some waiting around don't stop the clock. By 6 PM that's 12 hours, or two Timed Overdrives. Stay on until 8 PM and it's 14 hours, which is four. Go off duty for most of the night and come back to finish at 5 AM, and the clock still reads 23 hours, which is 13.

Mileage
Mileage Overdrives
Miles count in three steps, 450, 600, and 700, read straight off the odometer.
Distance counts in three tiers (see the chart). The lines are exact. 449 miles is zero. One more mile, 450, is one. 599 hasn't reached the 600 line, so it's still one. 600 is two.
The number comes off the odometer, the mile counter on the dash that shows what the wheels actually turned. A phone map won't do, because it skips the real miles: pulling off for fuel, the short run from the hotel to the venue, the odd drive between cities. Those all count.
The 700 tier mostly shows up out west, where the roads are open and the speed limits let a driver cover that ground safely in one legal day.
Miles add up across the calendar day, midnight to midnight, off the logbook. A 10-hour rest resets the time clock but not the miles, so same-day miles still add together. And crossing midnight on its own doesn't split them. That's Rule 7.
Example
A driver runs 300 miles to the venue. Later that day, a hotel run and a fuel stop add 160 more. The odometer now reads 460. That's past 450, so it's one Mileage Overdrive, even though neither drive felt long.

Operations
Claim Logic
Miles and the 10-hour time Overdrive don't add up together. You keep the bigger one.
Some days earn a Mileage Overdrive and the 10-hour Timed Overdrive at once. You don't add them. You keep whichever is bigger.
Say a driver runs 603 miles, which is two for mileage, and is on the clock 10 hours, which is one for time. The count is two, not three.
The longer-day Overdrives work differently. The ones at 12, 13, 14, and 15 hours always add on top, and so does every hour past 15. So do Off-Duty and Rule #1.
Overdrives are how the system marks a day that ran longer, or shorter on rest, than it should have.
Example
600 miles in a 10-hour day. Mileage says two, the 10-hour clock says one. The count is two, the bigger of the two. Not three.

Operations
Co-Driver Operations
The co-driver drives the miles the main driver can't legally finish, so the bus still reaches the next city.
Trigger 10 hrs drivingCounted per driverTwo drivers 900 mi at zeroBuyout set amount, each time
When you get one
The trigger is the 10-hour driving limit, not a mileage line.
A 650-mile highway run can fit inside 10 hours, so one driver might take it alone. Past about 600 the company usually adds a second rather than push one driver to the edge, which makes 600 a common signal rather than a rule.
How the miles split
Not 50/50. The co-driver covers what the main can't.
On an 800-mile run the main might drive 600 and the co-driver 200. If the main is near the 70-hour weekly cap, the co-driver takes the bigger share to save the main's hours. A tour manager may prefer an even split, but company policy governs.
Who counts what
Per driver, never per bus.
Each driver has their own miles, their own hours and their own logbook, which is the whole reason a second driver brings the number down.
Two drivers at zero
449 and 449 covers nearly 900 miles for nothing.
Keep each one under 450 for the day, give each a full 10 hours off before they drive again, and push a turn past midnight if same-day miles would cross 450.
Who claims it at the end
Mileage to both. Timed to whoever drove last.
On a 1,000-mile relay split 500 and 500, each driver turned 500 miles on their own log page, so both claim mileage. If the bus then waits five hours on room keys, only the second driver claims the Timed Overdrive, because the first went off duty in the bunk and stayed off duty through the whole wait. Those hours cost the first driver nothing and spend none of their 70 hours.
What counts as rest on the bus
A bunk, or the back lounge to themselves. Not the jump seat.
A couch back there is enough, since the point is having the space to yourself rather than what is in it. The jump seat is the second seat up front in the driver's area, and sitting there is riding in the workspace instead of resting, so the clock keeps running.
The hotel buyout
No bunk, hotel or back lounge means a set amount, each time.
It is not a share of the daily rate. Where the day rate is $450 the buyout might be $150, and it is paid on top of the hours the driver was on the clock.
Getting there and swapping
Fly in where the drive starts, fly home where it ends.
Or start at the pickup and ride along for the whole leg. Out on the road the two trade off at a truck stop, an exit ramp or a rest stop.
Example
An 800-mile drive. One driver alone eats three Mileage Overdrives. Split it, and the main does 600 (two) while the co-driver does 200 (zero). Nobody carries all three. Same bus, same miles, fewer Overdrives each.

7
Mileage
Logbook Total Miles
Whatever your log totals for the day is what counts. 450 or more is an Overdrive, and 10 hours off doesn't reset it.
Driving past midnight doesn't split your miles into two days on its own. The midnight-to-midnight line on the logbook only matters when one trip breaks into two separate drives.
Say a driver starts at 2 AM, runs 225 miles, takes 10 hours off, then runs another 225. If both land on the same day's log page, they add up to 450. That's a Mileage Overdrive.
This shuts a loophole. A driver can't stop just short of a line, rest, and reset to duck the Overdrive.
To actually split the miles, the second drive has to start on a new calendar day, at or after midnight. A 600-mile run cut into 300 and 300 on the same day still adds to 600, or two Overdrives, and it wrecks the driver's sleep. Run 300 on day one and the other 300 after midnight on day two, and each half is under 450. Zero Mileage Overdrives, and the rest falls into place.
Example
225 miles before a nap and 225 after, all on one calendar day. It feels like two short drives, but the log adds them to 450, which is one Overdrive. Start that second drive after midnight and it splits across two days, 225 and 225, for zero.
Midnight by itself doesn't split miles
Split drives on the same log page add together
