The primary color of a fire truck is typically red. This bright and attention-grabbing color is chosen for its visibility, allowing fire trucks to stand out in emergency situations and traffic. The color red has become synonymous with fire response and safety, making it a recognizable symbol for fire services globally. In addition to red, many fire trucks contain reflective stripes and other bright colors to enhance visibility, especially at night or in low-light conditions. The use of red helps communicate urgency and alerts the public to the presence of emergency responders.
