Local authorities are subject to a network management duty. Section 16(1) of the Traffic Management Act 2004 imposes a duty upon them not only to manage their road network, but to do so with a view to achieving objectives which include securing the expeditious movement of traffic upon the network. The duty is subject to reasonable practicability, and is elaborated upon in Section 16(2). In Trail Riders Fellowship v Devon County Council (2013) EWHC 2104 (Admin) the Court held that the highway authority had been entitled to make a Traffic Regulation Order prohibiting motor vehicles from using part of a road where that was expedient in the interests of road safety.

However, monitoring had continued, albeit on a less comprehensive basis than intended, and useful data obtained. A genuine experiment continued. Not revoking the ETO was not irrational. See especially para 101 of the Judgment, and the treatment at para 86 of Trail Riders v Peak District Authority (2012) EWHC 3359 (Admin).
