Alex Reif of Laughing Place asserted, "Firebuds teaches kids that the colorful vehicles with lights and sounds that enchant them on the roads have an important job to do. They can do their part by following the rules and playing safe. And when someone needs help, offer a hand if you're able. While the show isn't the first to tackle this same theme, it sets itself apart by including kids as both relatable humans and fun vehicles, and it is more reflective of the world we live in today to inspire the next generation of forward thinkers."[42] Ashley Moulton of Common Sense Media gave the series a grade of three out of five stars, complimented the educational value, saying the series teaches responsibility, and praised the positive messages and role models, stating the characters demonstrate teamwork and friendliness.[43]
