Those runaway truck lanes that exist on the side of some highways may look like a waste of space, but there's a good reason why they are completely necessary. Trucks, just like all vehicles, have braking systems. Given their much more significant payloads, their braking system are also much more substantial. However, when that system fails (perhaps with very little warning), it takes a lot more energy to bring a tractor trailer to a complete stop compared to a passenger car. This is where runaway lanes, truck arrester bed, emergency escape ramp, or whatever you call it, comes into play.

In the case of this Mexican runaway truck, it had lost its brakes for a good amount of time before the police finally came to provide escort. Thankfully, the driver was able to navigate the downhill sections of the highway well, and that there weren't too many motorists on the road. The truck, at some point, reached speeds of 100 mph according to the video's description. When it finally came upon a runaway lane, we can see how the gravel filled arrester bed was able to bring the massive truck to a complete stop. Luckily, the driver escaped unscathed.

  • He did not use the Retarder. Only the "normal" brakes.

  • You would leave it in gear and use the reluctor brake but that's all you have.he dealt with it perfectly good driving and handling the bends and those overtakes at the speed he was doing .

  • Car on neutral on downhill is a loose cannonball. It speeds up and at one point goes out of control, when your brakes is out. In this situation you either crash the car in most controllable way you can,, or you try to control the car down the road and slow it down on even road. On the even road you can slow down with gear reduction, slowing down with engine. Going downhill you can do that as well, but without brakes you accelerate only a little bit less... As there was traffic on the road, although small as it was, thankfully, he could not crash the car until he run into that construction place. If he crashed before, he would wrack not only car, but the road and other cars as well. He attempted to stop the truck on uneven, rough terrain, and he made it as best as it could be done. If there would be a leveled road, uphill would be better for decelerating but not actually stopping as he would at some point roll down in reverse, he could attempt to slow down with downshifting gears, and only in last faze rolling out to stop on neutral,

    So what this driver did what the best possible course of action at hand at that situation... Anyone who thinks that they would do better... you are daydreaming to much, and your ego will kill you one day, hopefully only you and not your families and other road users...

  • All the people in the comments saying shit like oh better matinence or put it in neutral. Science lesson if you give a 10 ton truck a trailer and add 1.5 tons too that plus the 2 ton trailer suddenly you have a disaster on wheels. If you brake going down that steep grade. Hey guys guess what. They get ripped off your truck or destroyed by the forces of idk just 13.5 tons of steel iron and metal. Now that's a little exaggerated. You can't stop a semi with trailer with no brakes or put it into neutral while moving. All while barreling down a mountain at 100plus MPh. If you think you can stop on. Go pro yourself while doing that and then send it to me

    • Ya neutral will only speed you up. Leave it in a gear with the jake on hope for a decrease in speed and downshift if you can

  • OK, my eyes are hurting from how wide they were through out this never ending disaster!

    Better maintenence could have prevented this? Asking! 🤔

    • not really because there is no way to check the brake system for a brake line that might give or something like that and besides the route is planned ahead so they knew they were going...

    • I see signs that say use engine retarder brakes only in certain areas.... 《(whatever that is) it's scary knowing these trucks don't have fail safe braking systems, (or do they?)...
