At 6:05 a.m. the phone rings: a driver has a fever, and their first stop is at 6:50. Every school bus company lives with this. What separates a calm morning from a scramble isn't luck — it's school bus driver substitute coverage planned ahead: a clear rule for how drivers call out, a list of trained substitutes who know the routes, and a short playbook the dispatcher follows without thinking.
This guide covers all three, plus what to tell the school and the district. For the time-off policy itself — sick days, vacation, notice — see our guide to writing a driver time off policy.
Three kinds of absence, three kinds of cover
| Absence | Notice you get | How it's covered |
|---|---|---|
| Planned — vacation, appointment, training | Days or weeks | Assign a substitute for just those days, and give them time to learn the route. |
| Call-out — sick, family emergency, car trouble | Minutes to hours | The morning playbook below: the first free substitute on the list. |
| No-show — the driver doesn't call | None | Spotted only if someone checks who hasn't arrived before the first pick-up. |
Most of your effort should go into turning the third kind into the second, and the second into the first.
Write a school bus driver call-out policy
A call-out rule only works if it's short, written down and the same for everyone. A typical one:
- Call, don't text — the dispatch number, and a second number if nobody answers. A text at 6:00 a.m. can sit unread.
- By a set time — for example, at least 90 minutes before your first pick-up, or the evening before when you already know.
- Say which runs — morning, afternoon, or both, and whether you expect to be back tomorrow.
- A no-call, no-show is handled under your attendance policy, the same way every time.
- Aides follow the same rule, so the office can find a substitute aide too.
Tip: Put the call-out rule on one card in every driver's wallet and on the wall by the time clock. The rule people can't remember at 5:45 a.m. isn't a rule.
Build a substitute bus driver list
Your substitute list is everyone who can legally drive a route and knows enough to do it safely. Look in more places than the obvious one:
- Spare or extra-board drivers — drivers you employ without a regular route, paid to be available.
- Part-time and retired drivers who'd take a day or two a week.
- Drivers with only one run — a driver who has a morning route may be free in the afternoon, and the other way round.
- Office staff, dispatchers, trainers and mechanics who hold a CDL with the passenger and school bus endorsements and have done your training.
Every name on the list must have the same qualifications as a regular driver: the right license and endorsements, a current medical card, background checks, drug and alcohol testing, and your state's training. Some states say so outright — New Jersey, for example, requires the same safety training for substitute drivers and aides as for permanent ones.
Make sure substitutes know the routes
- Route sheets for every route, with the stops in order, pick-up times, special instructions and each student's needs — see our route sheet template.
- Ride-alongs — have each substitute ride the routes they're most likely to cover, before they need to.
- Special needs routes first — a substitute on a special needs route needs to know each student's equipment and needs, and the aide.
- Same bus where possible — the substitute takes the regular driver's bus, so the students recognize it and the equipment is set up.
The morning call-out playbook
- Record the call-out: who, which runs, which days.
- Check who's on the substitute list and free at that run's times — not already driving another route then, not off themselves.
- Call the first one. If they can't, the next. Don't wait for a reply to a text.
- Put them on the route for just those days, with the same bus, and send them the route — stops, times, special instructions, students' needs.
- Tell the aide on that route who their driver is today.
- If nobody can cover, decide quickly: double back with a driver who finishes early, combine with a nearby route if the district agrees, or tell the school the run will be late or won't run.
- Before the first pick-up, check that every route today has a driver. A no-show is caught now, not when a school calls.
Who to tell, and when
- The school and the district, whenever a run will be late or won't run — before the first pick-up, not after. Your contract may say how and when.
- Parents, when the district or your contract expects it — the free parent letter templates include one for a late bus.
- The regular driver when they're back — anything that changed on their route while they were out.
Covering aides too
An aide calling out on a route that requires one is as urgent as a driver. Keep a short list of cleared, trained substitute aides, use the same call-out rule, and if nobody can cover a route where the student's plan requires an aide, tell the district before the run. Our guide to managing school bus aides covers aide absences in more detail.
Doing it in FleetCommander
With driver attendance and time off on (it's switched on company by company), FleetCommander finds the gaps and suggests the cover:
- A driver asks for time off under Time off on their phone, or the office records a phoned-in sick call with Add time off for a driver on Drivers › Time off — it's approved at once and the driver is told.
- When a driver with a route is off in the next 14 days and nobody else is on that run, the route is flagged Needs a substitute — in a yellow box on the route's page, and in Routes needing a substitute on the Dashboard — for each run (morning or afternoon) and day.
- The box suggests the best free drivers, chosen like Recommend a driver: home near the route, not on another route at that time, not off, and license and medical card in order. Press a name and they're put on that run for just those days, with the same bus, and told they have a new route with the dates.
- Drivers › Attendance shows who is Not in yet — a driver with a route today who hasn't clocked in — so a no-show shows up before the first pick-up.
- Planned cover can also be added on the route's page under Assignments, with a start and end date. A driver can't be put on two routes at overlapping times, so you won't double-book a substitute by mistake.
FleetCommander doesn't keep a separate "substitute" tag on drivers: your spare drivers are simply drivers without a route at that time, so they're the ones suggested first. The Drivers timeline shows everyone's day by the hour, which makes a gap easy to spot. For aides, there's no substitute suggestion yet: change the Aide on the route's Edit page, and the driver is told the aide changed.
Ava (Beta), the assistant in FleetCommander, answers the first question of the morning: Who's off today?, Who hasn't clocked in yet? and Which routes have no driver?. See her page.

Good to know: Driver qualification, training and notice rules differ by state and by district contract, and attendance and sick leave rules can be set by local law or a union agreement. Check them before you finalize your call-out policy.
Questions people ask
- How do bus companies cover routes when a driver calls out?
- With a call-out rule that gives the office time, a list of trained substitute drivers who know the routes, and a morning playbook: find a free substitute, put them on that run for the day with the same bus, and tell the school if a run will be late.
- Who can be a substitute school bus driver?
- Anyone with the same qualifications as a regular driver — the right CDL and endorsements, a current medical card, background checks, drug and alcohol testing and your state's training. Spare drivers, part-timers, retirees and office staff with a CDL are common choices.
- How early should a bus driver call out sick?
- Many companies ask for a call at least an hour or two before the first pick-up, or the evening before when the driver already knows, and ask drivers to call rather than text.
