These are required to protect structures such as bridges and tunnels from damage, or to restrict/prohibit use by vehicles that exceed specific dimensions, usually for environmental reasons. RestrictionForVehicles has been extended to support the full definition of height, weight, width and length restrictions as defined in the UK to ensure that they can: * Apply to specific vehicle types only. * Relate to a structure for which the restriction is designed to protect (for example, a Bridge). A RestrictionForVehicles will reference back to the Roads product through either a Node Reference or a Point Reference. The context diagram below shows how the RestrictionForVehicles has been inherited from INSPIRE and the attribution held on a feature.

## RestrictionForVehicles Height, Weight, Width and Length restrictions (HWWL) for vehicles. Measure shall be defined in metric units for width, height and length restrictions. For all weight restrictions, measure will be defined in tonnes and measure2 will not be supplied. ### id Unique identifier, for RestrictionForVehicle this is a TOID. * **Attribute name:** id * **Type:** CharacterString * **Size:** 20 * **Multiplicity:** \[1] ### identifier Uniform Resource Identifier. * **Attribute name:** identifier * **Type:** CharacterString * **Size:** 37 * **Multiplicity:** \[1] ### inspireId External object identifier of the spatial object. * **Attribute name:** inspireId * **Type:**[ Identifier](/os-downloads/products/transport-network-portfolio/os-mastermap-highways-network-routing-and-asset-management-information/os-mastermap-highways-network-routing-and-asset-management-information-technical-specification/data-types/identifier.md) * **Multiplicity:** \[0..1] ### beginLifespanVersion Date and time at which this version of the spatial object was inserted or changed in the spatial data set.

GitBook is the documentation platform designed so that both humans and AI agents can read, navigate, and reason over technical content effectively. Learn more at gitbook.com. ## Querying This Documentation If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question. Perform an HTTP GET request on the current page URL with the `ask` query parameter, and the optional `goal` query parameter: ``` GET https://docs.os.uk/os-downloads/products/transport-network-portfolio/os-mastermap-highways-network-routing-and-asset-management-information/os-mastermap-highways-network-routing-and-asset-management-information-technical-specification/rights-and-restrictions/feature-types/restrictionforvehicles.md?ask=&goal= ``` `ask` is the immediate question: it should be specific, self-contained, and written in natural language. `goal` is optional and describes the broader end goal you are ultimately trying to accomplish on behalf of the user. GitBook uses it to tailor the answer towards what is most useful for that goal. The response will contain a direct answer to the question and relevant excerpts and sources from the documentation. Use this mechanism when the answer is not explicitly present in the current page, you need clarification or additional context, or you want to retrieve related documentation sections.
