When is a truck required to have a passenger side mirror?

A truck is required to have a passenger side mirror when its Gross Vehicle Weight Rating (GVWR) is 10,001 pounds or more because this weight threshold is associated with larger commercial vehicles that are more challenging to maneuver. These vehicles have increased blind spots and require enhanced visibility to ensure safe operation on the road. Having a passenger side mirror is a crucial safety feature that helps drivers monitor adjacent lanes and prevents accidents that can occur due to impaired visibility. This requirement is in place to adhere to safety regulations aimed at protecting both the driver and other road users.

The other situations, such as having a GVWR of 8,000 pounds or more, not being contingent on trailer attachment, and the use of a rearview camera, do not align with the specific regulation regarding the requirement for a passenger side mirror, thereby clarifying the importance of adhering to established standards for vehicle safety.
