Couldn’t you just put the truck in neutral and use the regular brakes?

Engine brakes are required for slowing heavy loads, especially on long downhills. If you don’t use it the brakes will quickly overheat on a long downhill and become useless. [This](https://en.wikipedia.org/wiki/2019_Lakewood_semi-truck_crash) is what happens when a trucker doesn’t use engine brakes and overheats the service brakes. This driver also bypassed more than one runaway ramp.
