What color are permanent vehicle registration plates typically?

Permanent vehicle registration plates are typically white to ensure high visibility and reflectivity, which helps in identification and enhances safety on the road. The standardization to a white background allows for easy readability of the vehicle registration numbers and associated information, making it practical for law enforcement and identification purposes.

The colors blue, green, and red may be used for temporary registration, special plate designs, or specific vehicle classifications, but the traditional vehicle registration plates that are permanent and common on the roadways maintain a white color for consistency and clarity.
