Let’s talk about turn signals. Lots of people get pulled over for not using a turn signal. But what does the law require? The short answer is – 100 feet. You have to use them for 100 feet before you turn.
Here is the Texas Transportation Code 545.104
(a) An operator shall use the signal authorized by Section 545.106 to indicate an intention to turn, change lanes, or start from a parked position.
(b) An operator intending to turn a vehicle right or left shall signal continuously for not less than the last 100 feet of movement of the vehicle before the turn.
(c) An operator may not light the signals on only one side of the vehicle on a parked or disabled vehicle or use the signals as a courtesy or “do pass” signal to the operator of another vehicle approaching from the rear.
What does “required by section 545.106 mean?
Good question and the answer is, not much. Basically, 545.106 says your car has to have turn signals that are “approved by the department.” Which is weird since a different statute tells you all about what’s required for a turn signal in Texas. Which also answers this question-
What color can a turn signal be in Texas?
White of amber in the front, red or amber in the back.
Here’s the statute for reference-
(a) Except as provided by Subsection (b), a motor vehicle, trailer, semitrailer, or pole trailer shall be equipped with electric turn signal lamps that indicate the operator’s intent to turn by displaying flashing lights to the front and rear of a vehicle or combination of vehicles and on that side of the vehicle or combination toward which the turn is to be made.
(b) Subsection (a) does not apply to a passenger car or truck less than 80 inches wide manufactured or assembled before the model year 1960.
(c) Turn signal lamps:
(1) shall be mounted at the same level and spaced as widely apart as practicable on the front and on the rear of the vehicle; and
(2) may be included as a part of another lamp on the vehicle.
(d) A turn signal lamp shall emit:
(1) a white or amber light, or a color between white and amber, if the lamp is mounted on the front of the vehicle; or
(2) a red or amber light, or a color between red and amber, if the lamp is mounted on the rear of the vehicle.
(e) A turn signal lamp must be visible in normal sunlight at a distance of:
(1) at least 500 feet from the front and rear of the vehicle if the vehicle is at least 80 inches wide; and
(2) at least 300 feet from the front and rear of the vehicle if the vehicle is less than 80 inches wide
