What is the maximum speed limit for passenger cars on Texas highways during the day?

The maximum speed limit for passenger cars on Texas highways during the day is 70 mph. This limit is established to ensure safe and efficient traffic flow on highways where higher speeds are appropriate. The decision for this limit is based on various factors, including roadway design, traffic conditions, and safety considerations.

Certain highways, especially those that are well-maintained and designed for higher speeds, support this limit, enabling vehicles to travel efficiently while maintaining safety standards. Speed limits are set to balance speed, safety, and the overall flow of traffic, and 70 mph is deemed optimal for many Texas highways.

Other speed limits, such as 65 mph and 55 mph, may apply to different road types or specific conditions, but for typical highway driving, the rule for passenger cars during the day is 70 mph. This ensures that drivers can take advantage of Texas's extensive highway system safely.
