Law Enforcement Partners
Dedicated Police, Dedicated Partners
The Transit Police Division partners with local law enforcement agencies who provide assistance with uniform and plain-clothes patrol, special detail, investigations and behavior detection. Transit Police and agency partners patrol the system daily, assisting customers and enforcing RTD’s Code of Conduct and state laws. These partnerships allow for the closest available unit—whether with Transit Police or local law enforcement—to quickly respond to incidents on the system.
RTD thanks our law enforcement partners for helping keep you, and our system, safe.
