On my way home there is a stoplight with two lanes. After you go through the light it goes down to one lane after about 500 yards. If you are in the right lane, and going to the day care or credit union, you are good, if you need to continue straight, then you need to make your way left. Well without fail there are people in the wrong lane, and they will do crazy maneuvers to merge left, I'm always looking out for them, so I can hit the brakes and let them in if needed.
Today there was a semi truck (Lorry for those across the pond), in the right lane. I was already 3/4 of the way up, so I figured that I would keep going and he could pull in behind me, there was room. Then he started pulling into my lane with no turn signals at all! I had to pull into a small median (painted, not raised) and slam on my brakes to avoid driving into oncoming traffic. I then pulled back into my lane, I tried to get a plate number, but it was covered up by a fork lift mounted on the back (this can't be legal). His windows were blacked out (also illegal) and there was absolutely no identifying marks or company names on that truck.
I was tempted to follow him, but anyone that dangerous behind the wheel, that has gone to such lengths to hide any identifying marks, would likely be more dangerous face to face. If it hadn't been for that small median, he would have physically pushed me into oncoming traffic and there would have been nothing I could have done to prevent it.
