A driver radios in that a student didn't get off at their stop. Dispatch reads out the home address and a parent's phone number. It's a normal morning, but here's the question most directors never ask: who else just heard that?
The short answer
If your radio channel isn't encrypted, anyone with a scanner can listen in.
It takes a $100 scanner, a free phone app, or an online stream. No hacking needed, and in most US states listening is legal.
"Digital" doesn't mean private. Many scanners decode common digital radio formats unless encryption is switched on.
Why this matters
Think about what goes over your channel in a normal week: student names, home addresses, stop times, medical needs, behaviour incidents, and sometimes custody issues. Each call seems harmless. Put together, it's a clear map of where specific kids are, and when.
Some school and bus channels are already streamed publicly online. A quick search of your district name plus "scanner" can show if yours is one of them.
I once worked with a retired police officer who went on to become a high school principal. He loved telling stories from his police days, and one line always stuck with me:
"I got sick and tired of criminals constantly monitoring our airwaves."
We live in a world full of personal data, and there's no reason to give it away for free. For him, encryption wasn't a nice extra. It was a must. The four layers of encryption on LTE radios were a big part of why he chose them.

Your options
Option | Best for | Watch out for |
|---|---|---|
Add encryption to your current radios | Fleets with newer digital radios that already support it | May need new radios, software upgrades or licence changes. Basic "privacy" modes are easy to break. Ask for proper encryption. |
Train drivers on radio habits | Everyone, starting today | Only works if people stick to it. A stressed driver in an emergency will still say names. |
Switch to LTE push-to-talk radios | Fleets replacing old radios or needing wider coverage | Relies on cell coverage along your routes. Check signal in rural areas and dead spots first. |
What I'd do
After years of selling radios, here's my honest take:
Start with driver training, no matter what. It's free. Use stop numbers and student IDs instead of names and addresses.
If your radios are fairly new, ask your vendor if they support encryption and what it costs to turn on. Sometimes it's cheaper than you'd think.
If your radios are old or due for replacement, look at LTE. Encryption usually comes built in, and you skip the licence and repeater hassle.
Don't rip out a working system just for this. But don't buy new radios without asking about it either.
Quick checklist
Is our channel encrypted, or just "digital"?
Is our channel on any public scanner stream?
Do our drivers know what never to say on the radio?
If we buy new radios, is encryption included, or an extra cost?
