We understand every public agency is unique and every intersection is unique. We also understand California standards are much higher than the rest of the country, and that is the level of service we provide. 

RSI was founded on a vision of excellent customer service and an unwavering dedication to distributing innovative, reputable, reliable traffic products. We uphold a strong dedication to our suppliers. If we don’t believe in it, we won’t sell it.
