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

The nighttime maximum speed limit for passenger cars on Texas highways is 65 mph. This limit is established to account for the reduced visibility and increased danger associated with nighttime driving conditions. Driving at this speed is considered safe for experienced drivers on well-lit highways where visibility permits. Adhering to this speed limit helps ensure the safety of all road users, including pedestrians and cyclists who might be on or near the road, as well as the occupants of vehicles.

It is important to note that while some highways and conditions might allow for higher daytime speed limits, the nighttime limit takes into consideration factors such as potential fatigue, the increased likelihood of encountering wildlife, and the general decrease in visibility that occurs after dark.
