Transport disruption can occur at any time, due to extreme weather conditions and or accidents or other causes of obstruction. The County Council works with other agencies to ensure that our roads and communication links are kept clear. The Highways Agency has responsibility for provision of assistance to motorists on the major trunk roads in the County, being the M5, A38, A35, A30 and A303.
The Devon Road Network Shelter Plan (2.63MB - pdf help) gives guidance on assistance that would be given in the event that severe weather causes or exacerbates an incident that affects health and welfare of travellers on Devon's roads. The plan specifically covers both heatwave and severe cold weather including snow.
The Heatwave Plan for England is a plan intended to protect the population from heat-related harm to health. It aims to prepare for, alert people to, and prevent, the major avoidable effects on health during periods of severe heat in England.
The Cold Weather Plan for England is a framework intended to protect the population from harm to health from cold weather.
