Truck ABS is not nearly as good as car ABS. Right, @bobgrey1997? It's still possible to temporarily lock up brakes (especially on trailers), and even without full lock, sliding is still possible and realistic.
Example: this Volvo jackknifing on a slick road. Tires aren't stuck to the ground like they are in game.

The truck I used to drive never did have ABS on the trailer. Every time I hit the brakes, the trailers ABS light as well as a light on my dash for the trailers ABS would light up. All I could tell was some kind of software issue in the truck's computer wouldn't read the trailer connection correctly. As such, I have figured out ABS is quite useless. If the brakes are locking up, the simple solution (which is the exact same one ABS has) is to let off the brakes for a bit.
ABS is probably much "worse" in trucks simply because they are on a vehicle 80 times heavier.
It's not that they are worse, but rather that the brakes are under much more stress than those in a car, ajd much more prone to locking up, which gives the ABS more opportunity to mess up. That said, the weight of the vehicle can often help you stop in these cases. The main issue with locking up brakes isn't the lack of stopping power (the wheels aren't moving, so you theoretically have the highest possible braking power), but rather the vehicle "hopping" across the road (like a rock skipping across the surface of the water), so the wheels are no longer in contact with the ground. A loaded truck has a harder time doing this because of the weight, so your locked-up wheels have more contact with the ground.
Basically, ABS is more likely to fail in a truck than it is in a car, but this is less likely to prevent the vehicle from stopping.

Erm... ABS exists exactly to prevent this kinds of situations.
While ABS exists exactly to prevent the brakes from locking up and the vehicle sliding, they are not 100% effective, and very often fail to prevent it.
