Vehicle makes involved in fatal crashes, ranked or looked up by name.

Tool description as the model sees it

Vehicle makes involved in fatal crashes nationwide for a given year, from NHTSA FARS. Pass year alone to get the top makes ranked by vehicle-involvement count (e.g. “which vehicle makes show up most in fatal crashes in 2023”); pass make as well to get that one make’s involvement count across every loaded year. This is an INVOLVEMENT count, not a claim that the make caused the crash. Unknown makes are refused with a clear error naming a few valid makes, never an empty success.

Parameters

Name	Type	Required	Description
`year`	number	no	Calendar year, e.g. 2023. Required unless make is given (then optional, scoping to one year).
`make`	string	no	Optional: vehicle make, e.g. “Toyota”, “Ford”, “Harley-Davidson”.
`limit`	number	no	Max makes to return when ranking by year. Default 20, max 50.
