1. Negligence: If the trucker was driving negligently, such as speeding, following too closely, or failing to maintain proper control of the truck, they may be held liable for the damage to your windshield.
2. Debris on the road: If the trucker's windshield was damaged by debris on the road, and that debris then hit your windshield, the trucker may not be held liable as it was an unavoidable accident.
3. Mechanical failure: If the trucker's truck experienced a mechanical failure that caused debris to fly off and hit your windshield, the trucker may not be held liable as it was an unforeseeable event.
4. Comparative negligence: In some jurisdictions, comparative negligence may apply, meaning that if you were also partially responsible for the accident, your compensation may be reduced accordingly.
It's important to note that the specific laws and regulations regarding liability in these types of accidents can vary depending on the jurisdiction, so it's advisable to consult with a legal professional to determine your rights and options.
