Which colors are emphasized for enhancing vehicle conspicuity?

The emphasis on contrasting and fluorescent colors for enhancing vehicle conspicuity is rooted in the need for visibility and safety on the road. These colors stand out against various backgrounds, particularly in low light conditions or inclement weather. Bright and fluorescent shades, such as bright yellow, lime green, and orange, greatly enhance the ability of drivers to see vehicles from a distance, which is crucial during emergency situations or low-visibility conditions.

Contrasting colors also play a key role in making vehicles more noticeable compared to the surroundings. For instance, using bright colors on a vehicle in a predominantly green rural area will help the vehicle stand out more effectively. This practice is particularly important for emergency responders, where swift visibility can lead to quicker responses and reduced risk of accidents.
