If you got their license number report it to the police and GET a POLICE REPORT! Then go to them with the report and estimates to repair/replace the windshield. They will usually comply. Having things like "Stay Back 200 Feet" on the back of the truck does not release them from liability.
However, the determination has to be made that the object which caused the damage came from the bed of that truck - trucks are not responsible for items which came off the road, were picked up by their tyres, and then flung from the tyres. They are, however, responsible for damage caused by an improperly secured load, including material which is able to come out of the bed of their truck.
In the US, unless you have a Commercial Drivers Licence (CDL), you don't need any additional endorsements to operate a non-commercial vehicle with air brakes. If you're going for a CDL, then you need to take and pass the written test for air brakes, as well as road test on a vehicle equipped with air brakes.
There is no such requirement. According to the FMCSA, a Commercial Motor Vehicle is defined as being in commercial in nature, and having a Gross Vehicle Weight Rating of 10,001 lbs. and higher. So most 1 ton pickups fit this guideline when they're used for commercial purposes, and those don't have air brakes.
You complete the written air brakes test, and perform your road test in a vehicle equipped with air brakes.
You lose the ability to steer the vehicle, and usually it sends your car into a skid.
Not automatically, in any state. If you do not complete and pass both the written air brakes test, AND conduct and pass your road test in an air brake equipped vehicle, you will receive a "no air brakes" restriction on your licence which prohibits you from operating a commercial vehicle equipped with air brakes. This is only applicable to commercial vehicles, and does not prevent you from operating, for example, a motorhome equipped with air brakes (as motorhomes are exempt from FMCSR regulation).
There is no air brake endorsement. If a CDL driver does not complete and pass the written Air Brakes test and perform their road test in an air brake equipped vehicle, they receive a restriction which prohibits them from operating a commercial vehicle with air brakes.
On a US licence, there is no air brake endorsement - there is only a restriction for CDL drivers from operating a commercial vehicle equipped with air brakes if they don't complete the written test AND road test in a vehicle equipped with air brakes.
You lose the ability to steer the vehicle, and usually it sends your car into a skid.
The speed of the motor vehicle is gently slowed down. The more aggressive the brakes are applied the faster the vehicle slows down eventually coming to a full stop.
There is no air brake endorsement. If you do not pass the written air brakes test AND complete your road test in a vehicle equipped with air brakes, then you get a restriction which prohibits you from operating an commercial vehicle which is equipped with air brakes. It is possible to have a Class A CDL with an air brake restriction.
