Overweight Check for Converted Truck in South America
FR

Translated into English.

Hi Community,

We're heading to South America with our converted truck, which is a light vehicle (3,500 kg limit) that we’re shipping by boat in October this year (2026). But after weighing it, we’re at 4,500 kg. Based on your experience, do you think we’ll get stopped in South America (Uruguay, Paraguay, Argentina, Peru, Bolivia, and southern Brazil) because of this? Are there police checks for overweight vehicles? Has this happened to any of you?

Thanks in advance for your experiences and advice!

1 ton of overload—you’ve got to be brave to hit the road with that!!! If I were you, I wouldn’t be worried about weight checks, but mechanical failures like brakes that aren’t up to the job for that kind of weight. Safe travels.

Don’t answer the question asked. The reply is also irrelevant—what a shame for the forum!!

Hi, What’s a shame (and not just for the forum) is that it seems more important to know the risk of getting caught than the risk of causing accidents!

Note: just to get near the boat, you’re looking at a fine of at least 270 €, points lost on your license, vehicle impoundment, or even losing your commercial license—and therefore no insurance....

Good evening,

I don’t want to stir up controversy on this topic, but still... It means an uninsured vehicle, no valid license; we should at least tell people the truth. And how’s it getting to the port? On a truck?

Hey again—like my predecessors, what you're planning is pretty reckless. When you're driving a vehicle, you *really* feel the extra weight. Just taking a turn or braking is different. You’ve got to increase your braking distance *a lot*. And most roads in South America are winding and often unpaved. Sure, there are wide roads down there, but if that’s the case, you’re better off flying. So, can you tell us why you’re hauling an extra ton? Bringing a turbine or something? 😛

Well, if the topic doesn’t appeal to you, you know you’re not obliged to chime in, right? Have you ever driven a vehicle in your life?

Hi,

This isn't an answer to the thread, and my question isn't specifically for you, but I'd like to know what this site is that's reposting our discussions here. I don't believe I've given anyone permission to do that.

Can anyone shed some light on this?

Probably a 3.5T motorhome... overloaded... with just a regular B license!

Apologies to everyone (especially Cricri, Mathiew, and Tatra), because you all got worked up over our situation for nothing—and it’s our fault. Actually, our truck is a heavy goods vehicle (6.5t) that was downgraded to a light vehicle (3.5t), so it can easily handle an extra ton. We’d never dream of putting anyone at risk, least of all others...

My question is for travelers who’ve been to South America...

Thanks again for your concern.

PS: Thanks, Bernard

hi, to answer the question—the risk is getting stopped for an offense you didn’t commit and having to pay a fine, basically what’s called a mordida, especially if you’re driving with foreign license plates. Road checks are pretty common in Brazil, I think (they’re called fiscalia). Watch out for distances though—you might end up using a lot of fuel.

Really? I thought it was practically impossible, and systematically refused by the DREAL (especially since the empty weight of a 6.5t HGV is around 3.5t, ...).

Hi,

I apologize for insisting, but even if the truck was downgraded from 6.5 T to 3.5 T, it’s still not legal to drive it overweight at 4.5 T—even with a Class C license.

Nine months in Argentina, southern Brazil, Uruguay, Bolivia, Chile, and Peru—I didn’t see a single check on vehicle weight.

Thanks so much, Henryliz, for answering my question!

This morning, a speed check right outside my place. It’d been 15 months since they last showed up...

Hi there,

This is a bit of a gray-area situation, your story. Things might go smoothly; you might not have any issues anywhere, not have this point raised at customs, either going or returning—by the way, is the truck coming back? It’s likely that the weight checks that do exist won’t focus on what won’t be seen as a cargo vehicle. We can also bet you won’t have any reason to involve your insurance. In short, it’s a matter of mindset; there’s every chance things will go well. But things could also go very, very wrong. A risk to take—I’m not judging.

Hey, and regarding the budget, have you set a minimum budget? The heavier the vehicle, the more fuel it consumes—that makes sense, and it’s good to know. Especially with the Middle East crisis, prices have gone up. So, in the end, if you don’t have savings set aside, you might end up spending a fortune on fuel. Not trying to be pessimistic, but it’s something to think about. I’d recommend planning a route, measuring the distances you’ll cover, and doing some quick calculations—especially to figure out how much your vehicle consumes per 100 km.
