Well, this is where it gets a bit tricky. You see, this client is a government agency providing public services -- transit to be exact. Most, if not all of these images will be used in marketing campaigns that are aimed at public education. How to ride transit, New bus lanes, Changes in services, Project information for a public meeting, etc. I don't know if this qualifies as a commercial usage or not. I tend to err on the side of caution in such cases. Just not sure.
So your company has a contract with a government agency, can't they provide the legal guidance and constraints for your shoots?
