asked the Secretary of State for Transport what is the reason for certain parts of the A38 to have crash barriers and other parts not, both on central reservation and at the side of the road.

Safety fencing on trunk roads is erected at sites where fixed physical hazards exist for motorists, such as on high embankments, at structures and on sharp bends. The existing lengths of crash barriers on the A38 between Exeter and Plymouth are in keeping with this policy.
