How many exterior mirrors are required on a vehicle?

In Texas, a vehicle is legally required to have at least one exterior mirror. This requirement is important as it ensures that the driver has sufficient visibility of the area around the vehicle, particularly the rear blind spots, which enhances safety while driving. While some vehicles may come equipped with more than one mirror (such as a side mirror on each side), the minimum standard is one exterior mirror. This mirror could be located on either the driver or passenger side, allowing for adequate rearward visibility.

The other choices suggest either no mirrors or an excessive number of mirrors, which are not aligned with safety standards set for vehicles on public roads. Having two mirrors is common and recommended for optimal visibility, but the law specifically mandates just one as adequate for safety compliance. This foundational requirement ensures that all vehicles meet a basic standard for safe operation on the streets and highways in Texas.
