Texas Following-Distance & Headlight Rules

Question 1

Following-distance rule

Accepted Answer

Texas uses a two-tier following interval keyed to speed. At 30 mph or less, keep at least 2 seconds between your front bumper and the vehicle ahead. Above 30 mph, stretch that gap to 4 seconds. Add more time whenever the road is wet, crowded, or your vision is limited. New and less experienced drivers should default to the 4-second interval at every speed. To measure it, pick a fixed object at the roadside; when the vehicle ahead passes that object, count "one thousand-one, one thousand-two," and if your front bumper reaches the object before you finish the count, you are following too closely.

Question 2

Dim high beams within (ft): oncoming

Accepted Answer

500

Question 3

Dim high beams within (ft): following

Accepted Answer

300

Question 4

Headlight requirements

Accepted Answer

Texas requires headlights from 30 minutes after sunset until 30 minutes before sunrise, and any time persons or vehicles cannot be seen clearly for at least 1,000 feet. Switch to low beams within 500 feet of an approaching vehicle, when following within 300 feet of another vehicle, on lighted roads, and when driving in fog, heavy rain, sleet, snow, or dust. If you must park on an unlighted highway at night, leave your parking lights or low-beam headlights on.

Question 5

Min following distance behind emergency vehicle (ft)

Accepted Answer

500

Question 6

Motorcycle following rule

Accepted Answer

When following a motorcycle, allow at least four to six seconds of following distance so the rider has enough time to maneuver or stop in an emergency. When stopped behind a motorcycle at intersections, signals, or crossings, leave roughly a full vehicle length of space to help prevent pushing the rider forward if you are rear-ended.

Question 7

Cyclist safe-passing rule

Accepted Answer

Texas gives no number. State law tells you to pass to the left at a safe distance and not to pull back right until you are safely clear, and it leaves "safe" to your judgment and to the officer watching. Cities may set their own passing distances by ordinance, so the rule can tighten from one side of a city limit to the other. Two points decide most of these passes. A rider is not required to hug the curb when the lane is too narrow to share side by side, or when parked cars, debris or a coming left turn make the right edge the wrong place to be, so expect a bicycle in the middle of a narrow lane and treat it as a slow vehicle you have to go around properly. And when you turn right across a bike lane, merge with the bicycle traffic first rather than turning across it.

Question 8

Move over for a stopped emergency or service vehicle

Accepted Answer

Approaching a covered vehicle stopped on the road, most of them showing warning lights, vacate the lane closest to it if the road has two or more lanes in your direction; if you cannot, slow to 20 mph below the posted limit, or to 5 mph if the posted limit is under 25 mph.

Texas Transportation Code Sec. 545.157 is one of the broadest move-over statutes in the country. The covered classes in subsection (a) are: a stationary authorized emergency vehicle using visual signals; a stationary tow truck using authorized equipment; a TxDOT vehicle or a highway maintenance or construction vehicle under a state contract that is not separated from the roadway by channelizing devices and is using approved visual signals; a utility service vehicle using approved visual signals; a stationary vehicle used exclusively to haul municipal solid waste or recyclable material while collecting from a location next to the highway; a vehicle operated by or under contract with a toll project entity; a vehicle operated by an animal control officer or an authorized person removing an animal or carcass from the roadway; and a vehicle operated by a local-authority employee issuing a parking citation. Texas does not extend the duty to an ordinary disabled vehicle showing hazard lights: the trigger is the vehicle class. Most of the classes also require approved visual signals, but not all of them. The solid-waste and recycling class in subsection (a)(5) carries no signal condition at all; a stationary garbage truck collecting beside the highway is covered whether or not it is lit. Subsection (b) gives you a choice only when the road has two or more lanes in your direction: vacate the lane closest to the stopped vehicle. On a two-lane road, or when you cannot change lanes, you must slow to 20 mph below the posted speed limit when that limit is 25 mph or more, or to 5 mph when the posted limit is under 25 mph. The penalties are steep for what looks like a lane change: $500 to $1,250 for a first offense, $1,000 to $2,000 for a second within five years, a Class A misdemeanor if the violation injures someone, and a state jail felony for a repeat of that. A repeat offender can also lose the license for up to six months. The Texas Driver Handbook adds a non-statutory caution to slow and change lanes where possible for mail, delivery, and trash-collection vehicles making frequent stops.

Question 9

Defensive-driving framework

Accepted Answer

The Texas Driver Handbook teaches defensive driving as a set of habits rather than a named acronym like SIPDE, IPDE, or the Smith System. Chapter 14 gives four instructions: stay alert and keep your eyes moving so you always know what is happening around you, look for trouble spots developing on every side, have a plan of action ready before you need it, and remember that Texas law expects drivers to protect one another from their own mistakes. Study the habit, not a mnemonic; the exam questions track the handbook's plain-language wording.
