Where should yearly restricted area permit decals be applied on a vehicle?

The yearly restricted area permit decals must be applied to the lower left-hand corner of the windshield because this location ensures that the permit is clearly visible to security personnel and compliance officers. Placing the decal in this position allows for easy identification without obstructing the driver's view. Visibility is a critical component in maintaining security protocols at restricted areas like airports. Adhering to this requirement helps facilitate the smooth operation of security checks, ensuring that only authorized vehicles can access sensitive areas.

Other placements, such as on the rear of the vehicle or the dashboard on the passenger side, could hinder the ability of security personnel to quickly verify the permit, and placing it near the vehicle's license plate would not provide the same level of visibility needed for efficient identification.
