What Does the Minimum Speed Limit 40 Sign Mean?
When you see a R2-4 Minimum Speed Limit 40 sign, it means drivers must travel at a speed of at least 40 miles per hour under normal driving conditions unless traffic, weather, road conditions, or safety concerns require otherwise.
Vehicles should not drive slower than the posted minimum speed limit if doing so would disrupt the normal flow of traffic or create unsafe driving conditions for other road users.
This sign helps improve traffic flow, reduce congestion caused by unnecessarily slow vehicles, maintain roadway efficiency, and support safer driving conditions for all motorists.
