Speed Limit 45 Sign - Official Road Signage for 45 mph Zones #1778081 (License: Personal Use)

This is a federally standardized MUTCD-compliant speed limit sign, featuring bold, uppercase sans-serif typography for high visibility and readability at speed. The sign’s dimensions, font size, and contrast ratio meet FHWA specifications to ensure compliance and driver recognition under varied lighting and weather conditions. It is typically mounted on posts or overhead gantries along roadways where a 45 mph speed cap is legally enforced.

Used on municipal, county, and state roads-especially in residential areas, school zones, and secondary highways-to inform drivers of the legal speed limit. Matches user intent for traffic regulation reference, driver education materials, transportation planning resources, and signage compliance documentation.
