How often should the windshield be inspected for proper condition?

Answer: B — Before every trip

The windshield should be inspected for proper condition before every trip to ensure clear visibility and safety while driving. A well-maintained windshield is crucial for operating a vehicle, as it directly affects the driver's ability to see the road, other vehicles, and potential hazards. Inspecting it regularly allows the driver to identify issues like cracks, chips, or excessive dirt that could impair vision and pose a risk. This proactive approach helps prevent accidents and enhances overall vehicle safety. While performing inspections only once a month, every six months, or only when it looks dirty does not adequately address the need for consistent safety checks, a before-trip inspection ensures that any potential issues are identified and rectified before the vehicle is used on the road. This practice is vital for maintaining the safety standards required in commercial driving.
