Cevap

Amber is the required color for all front-facing clearance lights, identification lights, and front side marker lights.
Under commercial vehicle safety regulations, all clearance lights, identification lights, and side marker lights mounted on the front or front sides of the vehicle must be amber to clearly delineate vehicle size to oncoming drivers.

Adım Adım Çözüm

1
Recall regulatory standards for commercial vehicle exterior lighting positions and colors.
Federal and state commercial vehicle safety regulations specify that forward and front-side lighting (other than headlights) must be amber.
Amber signals vehicle presence and dimensions to oncoming traffic without causing glare or confusion with rear red lights.
2
Evaluate the choices to find the color designated for front clearance and identification devices.
Amber is confirmed as the correct and mandatory color.
Red belongs on the rear, white is reserved for illumination lamps (headlights/reverse), and blue is prohibited.
