What color are reflex reflectors supposed to be on the sides of vehicles?

Reflex reflectors on the sides of vehicles are specifically designed to enhance visibility and safety on the road. The correct color for these reflectors is amber. This color serves a critical purpose in signaling the presence of a vehicle, particularly as it relates to its width and position on the road, helping other drivers gauge distance and clearance effectively.

Amber reflectors are commonly used on the sides of vehicles because, in low-light conditions or during poor visibility, they provide a clear indication of where the vehicle is located. This is essential for preventing accidents, especially in scenarios where visibility is compromised.

Understanding the significance of using amber reflectors is crucial for both safety inspectors and vehicle operators, ensuring that vehicles meet safety standards and contribute to overall road safety. The other colors typically associated with vehicle lighting and markings serve different purposes, such as red for brake lights or blue for law enforcement vehicles, which is why those options do not apply to side reflectors.
