What Is the Max Speed Limit in Every State?

Introduction to U.S. Speed Limits

Speed limits in the United States vary widely by state, influenced by geography, population density, and road design. Established by state governments with assistance from transportation departments, these limits balance safety and traffic efficiency. Previously, the federal government set a nationwide limit of 55 mph in 1974 to conserve fuel during the oil crisis; this was repealed in 1995, giving states full authority.

Current Speed Limits Overview

Today, maximum speed limits range significantly, from 55 mph in Hawaii to 85 mph on select Texas highways. Rural interstates typically feature higher limits, while urban areas and locations with distinct safety concerns usually have lower caps. States like Montana and Nevada have limits up to 80 mph, contrasting with densely populated or safety-focused states like Hawaii.

Factors Influencing Speed Limits

State-specific limits consider geographic conditions, population density, engineering studies, accident statistics, and public feedback. Enforcement varies, affecting driver compliance and roadway safety. To aid traffic safety, tools such as traffic cones and speed bumps provided by the Traffic Safety Store are frequently utilized. Note: local roads, school zones, and construction areas may have lower posted limits. Some states adjust speeds for trucks or nighttime driving—check with local agencies for specifics.
