That's scary, likinbikin. Glad you could keep the bike under control. I think that alot of truckers need physics lessons on bow shocks and fluid dynamics. They don't always realize how the airflow around their trucks impacts the space beyond the vehicle, and how that space increases with speed. I've had buses pass me at 40 mph within touching distance. Semis at 60 are much worse. I have written to our local bus authority when I felt a driver was operating dangerously by passing too close, and the bus authority has responded. If you know the trucking company name, you could write to them and suggest they provide more training for drivers around cyclists. If a driver can't pull over to give you adequate space, he should be SLOWING DOWN.

You might consider tires like Gatorskins that could run over broken glass without too much danger of a puncture. Those roads you ride on sound dangerous when you can't use the shoulder.
