MIRRORS & BRACKETS

Mirrors & Brackets For Peterbilt Trucks

Mirrors are a federal safety requirement on commercial trucks and the driver's primary tool for managing blind spots on a Class 8 rig. A cracked mirror glass, broken housing, or loose bracket that allows vibration blur at highway speeds is both a safety hazard and an inspection violation. We carry main mirrors, spot mirrors, hood mirrors, fender mirrors, and mounting brackets for Peterbilt trucks — including heated mirror options for drivers operating in cold-weather climates where frost and ice are regular concerns.

Frequently asked questions about mirrors & brackets

What mirrors are required by FMCSA on a Peterbilt truck?

FMCSA requires commercial motor vehicles to have mirrors providing a view of the highway for a distance of 200 feet to the rear on both sides of the vehicle. In practice, this means properly adjusted main mirrors on both the driver and passenger sides are mandatory, and both must be free of cracks or distortion that would impair the driver's view. Additional spot, hood, and fender mirrors are recommended for blind spot management but are not specifically mandated beyond the rear-view requirement.

Why does my Peterbilt mirror vibrate at highway speeds?

Mirror vibration at speed is almost always caused by a loose mounting bracket, worn mirror arm pivot points, or a bracket that's been bent from a side strike and no longer holds the mirror head rigidly. Start by checking all mounting hardware for tightness — vibration works fasteners loose over time. If the bracket is intact and tight, the mirror head pivot or base may have worn pivot points that allow the mirror to oscillate. Replacement of the bracket arm or mirror head resolves most vibration issues that can't be cured by tightening.

Are heated truck mirrors worth it on a Peterbilt?

For drivers operating in northern states or Canada during winter months, heated mirrors are a significant safety upgrade — frost and ice on an unheated mirror can obscure rearward visibility entirely within minutes of stopping in freezing precipitation. Heated mirror elements connect to the truck's electrical system through a simple switch or automatically through the rear defrost circuit on equipped trucks. The modest electrical draw of a heated mirror element is well worth the visibility benefit in cold-weather operation.
