What is the top speed limit for heavy trucks on the open highway during the daytime?

The top speed limit for heavy trucks on the open highway during the daytime in Texas is 60 mph. This limit recognizes the need for safety and control over larger vehicles, which may take longer to stop and require more distance to maneuver compared to lighter vehicles. While there are higher speed limits for cars and some lighter vehicles, limiting heavy trucks to 60 mph helps reduce the risks associated with speed differentials on the road. This speed limit is established to enhance road safety for both truck drivers and other road users, maintaining a balance of efficiency and safety on Texas highways.
