A living source register, not a forgotten links page.

TowSmart fingerprints each official page or document on a schedule. When its bytes change, the affected record leaves the public library until the new version, effective date and plain-language description have been reviewed.

Important:

TowSmart provides access to official sources and general navigation help. It does not provide legal advice, engineering certification, a roadworthy certificate or approval to modify a vehicle. Requirements depend on the vehicle, manufacture date, intended modification and jurisdiction. The issuing authority’s current material always governs.
