Let me tell you—back when I first started writing about simulation games, the idea of using codes to unlock perks felt like a bit of a cheat. But now? Honestly, it’s just part of the game culture. If you’ve spent any time in Truck Simulator on Roblox, especially the Big Rigs mode, you’ve probably seen people buzzing about game codes, asking for the latest ones, or bragging about the rewards they got. And yeah, I’ve been there too—digging through forums at midnight trying to find a code that actually works.
Truck Simulator codes aren’t just some random gimmick. These things unlock real value—extra cash, new trucks, in-game perks, and even exclusive items you can’t get any other way. The developers drop them as rewards, promotions, or during events (usually unannounced, which is half the fun and half the frustration). Some expire fast, others stick around for weeks. It’s a mix of timing, luck, and knowing where to look.
Now, if you’re wondering what all this really means—and how to find and redeem codes in Truck Simulator without wasting time—I’ve got you covered. Let’s get into the good stuff.
Latest Active Truck Simulator Big Rigs Codes (September 2025)
If you’ve been grinding deliveries in Truck Simulator: Big Rigs this month, you’ll know how quickly those fuel costs and rig upgrades start adding up. And if you’re like me—always chasing that next bonus truck or just trying to stay ahead of the curve—keeping up with the latest active codes is essential. Now, I’ve seen months where the devs barely dropped a single working code, but September’s actually looking pretty decent (for once).
Here’s a quick comparison of this month’s active Truck Simulator codes, what they unlock, and—importantly—when they expire. I added a few notes based on my own experience with each reward.
| Code | Reward | Expires | My Take |
|---|---|---|---|
| RIGSUPGRADE25 | 25,000 in-game cash | Sept 30, 2025 | Solid starter boost—great if you’re upgrading trailers or cab interiors. |
| HEAVYHAULZ | Bonus Big Rigs truck skin | Sept 28, 2025 | Not bad. The skin’s slick, but purely cosmetic (so don’t expect performance). |
| CARGOKING | Free cargo boost (2x cash) | Sept 25, 2025 | My favorite this month—stack this with a long-haul job and you’re golden. |
| EXTRAAXLES | Suspension upgrade voucher | Sept 30, 2025 | Functional reward. Helps if your rig struggles with heavier loads. |
How to Redeem Big Rigs Codes in Truck Simulator (U.S. Players Guide)
Okay, so I’ve had way too many friends ask me how to enter codes in Truck Simulator: Big Rigs—and honestly, I get it. Roblox games don’t always make this process as obvious as they should. Especially on mobile. I’ve fumbled through the interface more than once thinking, “Where’s that redeem button again?” So here’s the step-by-step rundown that’s worked for me (and hasn’t changed in months, thankfully).
- Open the game on your device (I usually play on mobile, but it’s the same on desktop).
- Tap the gear icon in the corner—this takes you to the Game Settings menu.
- Look for the “Redeem Code” tab—you might need to scroll depending on your screen size. (Weird UX choice, but hey.)
- Tap the input field, then enter your code exactly—caps and all. Some codes are case-sensitive, and I’ve messed that up more than I care to admit.
- Hit the “Redeem” button and wait for the pop-up.
- If it’s valid, you’ll get a success alert (usually in green) and the reward lands instantly.
- If it’s expired or already used, you’ll get the dreaded error message. Happens.
What Rewards Do Big Rigs Codes Unlock?
Now, if you’ve been playing Truck Simulator: Big Rigs for more than a few hauls, you already know the grind can get real—fast. I remember the early days when all I wanted was enough in-game dollars to afford a basic upgrade without selling off my best trailer (yep, rookie mistake). That’s where these codes come in. They’re not just fun little extras—they’re actual shortcuts to making progress without shelling out Robux every five minutes.
Here’s what you can unlock with active codes:
- In-game Cash – The most common reward by far. Usually ranges from $5,000 to $50,000.
(Best used when you’re just starting or saving for that next truck upgrade.) - Exclusive Trucks or Skins – Some codes give you a whole rig or limited-edition cosmetic.
(I still use that chrome flame skin from the summer drop—it just hits different.) - XP Boosts – Temporary experience multipliers that help level you up faster.
(Helpful if you’re trying to unlock parts in the Garage without hauling forever.) - Custom Parts or Vehicle Mods – Suspension upgrades, lights, exhausts… that kind of stuff.
(Not every code drops these, but when they do—grab it.) - Bonus Inventory Items – Fuel, repair kits, and sometimes random loot-type rewards.
(They’re small, but honestly, they’ve saved my rig more times than I can count.)
