Practice point: The installation of a traffic control signal, where it had not previously existed, is a discretionary governmental function that does not give rise to state liability. However, liability is imposed where there is a failure properly to maintain an already established traffic ligh, and where that failure was a proximate cause of the accident.
Student note: The state has a non-delegable duty to maintain the roadway in safe
