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

The maximum speed limit for passenger cars on highways in Texas is 70 mph. This speed limit is determined by the Texas Department of Transportation and is applicable under ideal driving conditions. It reflects the need for a balance between efficient travel time and safety on highways, which are designed for higher speeds compared to urban roads. When driving on these highways, familiarizing oneself with the posted speed limits is crucial for complying with state laws and ensuring safe travel.

While some highways may have different speed limits, such as 60 mph or 65 mph, they generally apply to specific areas or conditions, like near urban developments or in zones with higher pedestrian traffic. The highest designated speed limit can extend to 75 mph in certain rural areas, but for passenger cars on highways, the standard maximum is set at 70 mph.
