Are There Times When Daytime Headlights Are Required in Texas?

We all know that headlights are required at night. In fact, Texas Transportation Code §547.323 specifically requires headlights to be on 30 minutes after sunset to 30 minutes before sunrise. That's common sense.

Many drivers don't know that the code also requires headlights to be on in certain daytime driving situations. In some states, like Arkansas, the law states that headlights must be on whenever the windshield wipers are on.

That is not the case in Texas.

The code for Texas states that headlights must be illuminated when visibility is less than 1,000 feet. That is the distance of about three city blocks in downtown San Angelo.

While the Texas Code does not require headlights for driving in fog, smoke, or other low visibility situations, Texas law does require drivers to exercise due care when operating a motor vehicle which includes adjusting their driving behavior and using appropriate safety equipment like headlights in response to changing road and weather conditions.

Do Daytime Running Lamps Satisfy the Requirement for the Times When Daylight Headlights are required in Texas?

Texas Transportation Code §547.323 seems to indicate that they do.

According to the code, "a motor vehicle may be equipped with and use daytime running lamps that emit a white or amber light, are activated by the motor vehicle's ignition, and comply with applicable federal standards."

However, it is important to note that daytime running lights are not a substitute for headlights in all low-visibility situations and may not provide sufficient lighting for the driver to see the road or to be seen by other drivers. In those situations, regular headlamps are probably a safer option.
