Vehicle used for agricultural purposes. Vehicles operated by a car-sharing company. Vehicles that are used to deliver goods in a city area. Vehicle which is limited to non-private usage or public transport usage. Vehicle used by the emergency services. Vehicle used by the military. Vehicle used for non-commercial or private purposes. Vehicle used as part of a patrol service, e.g. road operator or automobile association patrol vehicle. Vehicle used to provide a recovery service. Vehicle used for road maintenance or construction work purposes. Vehicle used by the road operator. Vehicle used to provide an authorised taxi service. Details of atmospheric visibility. The minimum distance, measured or estimated, beyond which drivers may be unable to clearly see a vehicle or an obstacle. Types of road surface conditions which are related to the weather. Severe skid risk due to black ice (i.e. clear ice, which is impossible or very difficult to see). Deep snow on the roadway. There is no humidity over the sensor. The wet road surface is subject to freezing. The pavements for pedestrians are subject to freezing. Severe skid risk due to rain falling on sub-zero temperature road surface and freezing. Fresh snow (with little or no traffic yet) on the roadway. Glaze of the road surface. Increased skid risk due to ice (of any kind). Ice is building up on the roadway causing a serious skid hazard. Ice on the road frozen in the form of wheel tracks. Severe skid risk due to icy patches (i.e. intermittent ice on roadway). Powdery snow on the road which is subject to being blown by the wind. From (0,01 mm) water film thickness over the sensor Conditions for pedestrians are consistent with those normally expected in winter. The road surface is not dry. Packed snow (heavily trafficked) on the roadway. Fresh snow (with little or no traffic yet) on the roadway. The road surface is melting, or has melted due to abnormally high temperatures. Detection at least of the presence of partly or wholly solidified aqueous solution over the sensor. Increased skid risk due to melting snow (slush) on road. Melting snow (slush) on the roadway is formed into wheel tracks. Fresh snow (with little or no traffic yet) on the roadway. Snow drifting is in progress or patches of deep snow are present due to earlier drifting. Snow is on the pedestrian pavement. Increased skid risk due to partly thawed, wet road with packed snow and ice, or rain falling on packed snow and ice. Snow is lying on the road surface. Partly thawed, wet pedestrian pavement with packed snow and ice, or rain falling on packed snow and ice. From (2 mm) water film thickness over the sensor. Water is resting on the roadway which provides an increased hazard to vehicles. From (0,2 mm) water film thickness over the sensor Other than as defined in this enumeration. Type of weight - describing the meaning of a vehicle weight value The weight is the actual weight of a specific vehicle The weight is the maximum permitted weight for a vehicle Width characteristic of a vehicle. The operator to be used in the vehicle characteristic comparison operation. The maximum width of an individual vehicle, including any features embedded or fixed on it, in metres. Wind conditions on the road. The height in metres above the road surface at which the wind is measured. The wind speed averaged over at least 10 minutes, measured at a default height of10 metres (meteorological standard) above the road surface, unless measurement height is specified. The maximum wind speed in a measurement period of 10 minutes. The average direction from which the wind blows, in terms of a bearing measured in degrees (0 - 359). The direction from which the maximum wind blows, in terms of a bearing measured in degrees (0 - 359). The average direction from which the wind blows, in terms of points of the compass. The direction from which the maximum wind blows, in terms of points of the compass. A measured or calculated value of wind speed. A value of wind speed expressed in metres per second. Instructions relating to the use of winter equipment. Do not use stud tyres. Use snow chains. Use snow chains or snow tyres. Use snow tyres. The carrying of winter equipment (snow chains and/or snow tyres) is required. Other than as defined in this enumeration. A year.
