How Admiral Freight Used Laziness to Engineer Smarter Trailer Security

At Level5Fleet, we like to say we’re tech visionaries. Our idea of innovation involves heated debates over automating microwave popcorn (which ended badly, thanks for asking). Truthfully though, we’re not always dumb—sometimes we’re just plain lazy.

But here’s the thing: lazy engineers make excellent engineers. Why? Because they find the smartest, most efficient ways to avoid repetitive, tedious work. Which brings us neatly to trailer security and Admiral Freight.

What Is Admiral Freight?

Admiral Freight isn’t a broker, a TMS, or a load board. It’s a freight protocol infrastructure — a layer that standardizes how loads are priced, secured, and verified.

• On the pricing side, it replaces haggling with protocol fairness: shippers post what they’re willing to pay, carriers post their minimum, and the platform automatically matches at the midpoint.
• On the security side, it enforces identity and route verification using embedded trailer hardware.
• And on the operational side, it automates compliance from dock to dock — no guesswork, no clipboard checks, and definitely no faxes.

It’s a structural fix for a structurally broken system — designed to make security scalable and pricing fair.

In this post, we’re pulling back the curtain on one of our trailer security mechanisms. Don’t worry — we promise to keep it light and entertaining.

Meet Your Typical Freight Thieves

Freight thieves come in three flavors:

1. Strategic Thieves: Sophisticated criminals with fake IDs, fake paperwork, and terrifyingly real plans. We handle those with advanced in-load communications and protocol enforcement.
2. Opportunistic Thieves: Less strategic, rivaling us in laziness — more opportunistic. They grab whatever they can while you’re fueling up your truck (and yourself with donuts).
3. Classic Hard Workers: Traditionalists who go the extra mile to steal the entire trailer itself, and take it somewhere safe to unload the goods while humming their favorite villain tunes (if movies are to be believed, that’s usually a Michael Jackson’s tune).

It’s the classic hard workers that drove us to step up our lazy engineering game.

Immobilizing a Trailer Without an Engine

Admiral Freight immobilizes trailers to stop these old-school thieves. Simple, right? Not quite. Trailers don’t have engines to disable. Sure, we could immobilize the tractor, but thieves know exactly which one to steal.

Our solution? The humble parking brake. We transparently prevent or allow drivers to pressurize the line to release the parking brake. Think of it like your car’s keyless entry.

It’s non-intrusive and requires no workflow changes from honest drivers. Just connect and go—assuming you’re actually Bob. If you’re not Bob, surprise! The trailer stays put.

Serious Engineering for Lazy People

Here’s the catch: the parking brake is also a failsafe in case the service brakes fail. If you were to block pressure to it at the wrong time — say, when the vehicle’s already in motion — it would disable the emergency fallback system. That’s not just bad—it’s “explain-it-to-the-lawyers” bad.

So, we engineered a triple-layered redundancy to make that scenario virtually impossible—each layer being doubly redundant:

• Passive Layer: Electrically isolates the valve. If the switch is off, nothing happens.
• Logic Layer: Confirms the trailer isn’t moving and isn’t connected to the tractor before switching.
• Architecture Layer: Ensures the immobilizer can’t be remotely activated. You can only request it — the trailer decides whether it’s safe. No overrides.

Let’s take a closer look at the logic layer — a particularly fun one for lazy engineers.

Detecting Motion Without Breaking the Bank

We considered using fancy laser-ring gyros like the ones in airliners. Then we remembered: we want this to be affordable.

So we used GPS and accelerometers. Simple logic: if both say the trailer is stopped, then it’s probably stopped — and they won’t wreck your coffee budget.

These two sensors have very different failure modes, which makes them great complements. It would be quite the feat for both to mistakenly think the trailer is stopped while it’s actually in motion.

But here’s the twist: accelerometers don’t detect motion, they detect changes in motion. So, at a steady speed, they appear idle — even though the trailer’s cruising down I-80. That’s a problem.

The fix? Analyze vibration patterns in all three axes to determine whether the trailer is truly stationary. You’d need to collect raw sensor data, filter out road noise, normalize for trailer type, and classify behavior under a range of conditions — all while trying not to invent a new PhD thesis. The graph below from one of our road tests shows how the raw sensor data looks like.

Laziness to the Rescue: Machine Learning

Could we manually classify vibration patterns? Sure. Did we want to? Absolutely not.

Lazy engineers do what any respectable procrastinator would: train machine learning models to do the hard part.

(We like to say that ML is the intern who works 24/7 and doesn’t ask for snacks — we just take the credit.)

So here’s what we built:

• ML algorithms analyze vibration signatures using accelerometer data to classify whether the trailer is stationary or moving.
• GPS confirms whether speed is zero.
• If both agree, we proceed to check if the trailer is still connected to the tractor.

No assumptions. Just structured laziness, powered by rigorous design.

The Result? Admiral Freight Just Works

If the driver is authorized to pull the load, the immobilizer disengages silently — the driver never even knows it was there.

There’s more nuance when it comes to live loads versus drop-and-hook scenarios, but that’s a story for another day.

We joke about being lazy, but laziness is really just efficiency with attitude. At Level5Fleet, good engineering isn’t about working harder — it’s about engineering smarter. Admiral Freight embodies that philosophy, combining triple-layer redundancy, intelligent motion detection, and machine learning.
