Here's one of those things you always hear about, but very few have actually seen happen.It was at precisely 2:05 pm today when I saw it. As it unfolded in front of me, I said to myself, no - it couldn't be.
It was a newer tan GMC Yukon. It was tooling down the 405 freeway SB near the Santa Monica Blvd in the number 2 lane, or the lane directly to the right of the fast lane. It was towing a pretty big enclosed motorcycle trailer, or what most people know as a "toy hauler". The truck/trailer combo was traveling pretty much with the flow of traffic. The guy driving the combo wasn't driving fast, weaving in/out of traffic or otherwise being a nuisance. No, this guy's problem was instigated by a slight oversight on his part, even before he pulled out of his driveway that morning.
The 405 freeway is known for it's choppy characteristic when driving on the 50 year old concrete square panels laid end to end to create most of the massive black ribbon that is the 405. The panel cause a constant modulation effect that travels from the road itself, up through a vehicle's tires, suspension and chassis until it reaches the driver's bones, which get rattled to high Heaven. This constant pulsing effect can cause another effect as well.. a much more destructive effect.
As I passed the truck/trailer, I noticed the front of the trailer was bumping up and down much more than the rear of the truck it was supposed to be attached to. Just as I glanced over, I saw the tongue of the trailer pop off it's hitch. It bobbed up and down 2-3 times before it finally hit the road and threw off a shower of sparks. The safety chain was doing it's job, but it didn't keep the trailer to yaw back and forth as the truck driver tried to quickly pull over to the side of the road. As I passed him and continued on, I saw him signalling and merging to the right as fast as possible.
Lesson to the world; It doesn't take a Highway A-hole to forget to tighten down your trailer ball hitch before leaving on a Memorial Day Weekend vacation at Glamis.
