[ WP ] There is a black market that only happens between adjacent tractor trailers ( semi-trucks ) on the highways , where goods are tossed between open-sided trailers . Describe an experience with this market .

Lou tapped the steering wheel as he cruised down the long, empty stretch of road. He gazed lazily at his clock, quickly realising the time and sitting up straight, alert. Two minutes passed before he saw the speck in his wing mirror. He slowed to 60mph and rolled up his window, just as the sound of the other trucks engine started creeping into the cabin. 
 
 The following truck approached quickly, and within a minute it was only a copule of car lengths behind Lou's trailer. There was a knock from the panel behind his head, and he flashed his hazard lights. The other truck slowly pulled up beside, and Lou steered the huge vehicle closer to the dividing line. As the two drivers became parallel, they gave each other a small nod, then continued to keep an eye on the road. All the drivers wore caps and sunglasses - most had beards or moustaches, to ensure they could n't be identified. Lou did n't even know who and what was in the back of the truck. 
 
 Earlier in the day, Lou had driven to a truck stop, where a marked trailer was waiting for him. A bag of money was hidden underneath, which was the first part of his payment. The bag also contained his `` deliver instructions'' which usually contained a time and place for the transaction. This ensured anonymity for the driver and the two parties carrying out the trade. As normal, after the deal was completed, Lou would stop at another designated location, where another hidden bag of money would be waiting for him, and unhitch the trailer. The work was easy, and it paid very well. 
 
 
 Today was not a normal day however. Lou heard raised voices behind him, and suddenly became more alert. He heard muffled shouting, and then a loud bang blasted through the cabin. Screaming and gunshots followed, and before Lou could react, the other driver raised a shotgun to his window and fired. 
 
 Instinctively, Lou flinched and hunkered down in his chair, slamming his foot on the accelerator. He threw his head up to steer the vehicle back into the middle of the road, ignoring the shotgun pellets which had embedded themselves in his bulletproof window. Lou looked out the wing mirror and saw the other truck roll off the road and coast to a halt. He drove for what felt like an eternity until all he could see behind him was the horizon. 
 
 
 
 
 My first prompt, maybe needs a bit more fleshing out but it's late. Thanks for reading: )
