DES MOINES, Iowa (AP) — A state judge has ruled that the Iowa Department of Transportation has the authority to order cities to remove automated traffic-enforcement cameras from highways and interstates. The Des Moines Register reports that the ruling Thursday is in response to a request for judicial review filed by Des Moines, Cedar Rapids and Muscatine in 2015. The cities made the request after the DOT ordered some speed cameras turned off because they did not make interstate highways safer.

DES MOINES, Iowa (AP) — The Iowa Legislature approved an expanded medical marijuana oil program in the final hours of its session, but advocates remain skeptical that it will have enough impact. The Republican-controlled chambers approved a bill to allow the oil to treat nine conditions, including cancer and multiple sclerosis. Critics say a cap on the strength of the oil that can be used limits the medical benefit.
