What is the recommended speed limit when driving a semitrailer on FM and Ranch Roads?

The recommended speed limit when driving a semitrailer on FM (Farm-to-Market) and Ranch Roads is typically set at 60 mph for cars and 55 mph for trucks, which includes semitrailers. This speed limit is established to ensure safety given the conditions commonly present on FM and Ranch Roads, such as rural settings, limited visibility, and increased likelihood of encountering slower-moving vehicles, livestock, or obstacles.

Maintaining a speed limit of 55 mph for trucks helps mitigate the risks associated with driving larger vehicles, which have longer stopping distances and less maneuverability compared to passenger vehicles. It balances the need for efficient transport while ensuring the safety of all road users, particularly in areas that may not be well maintained or are frequently trafficked by agricultural vehicles.

In contrast, other speed limits mentioned do not align with the guidelines for heavy vehicles on these types of roads and could lead to unsafe conditions. Recognizing the specific regulations for truck travel on FM and Ranch Roads is crucial for compliance and ensuring road safety.
