Workers and responders stopped on the roadside are extremely exposed. Texas's Slow Down or Move Over law protects them. Texas also bans street racing in every form, with penalties up to a felony.

The law covers these vehicles when stopped on the road with lights activated:

  • Emergency medical vehicles
  • Law enforcement vehicles
  • Fire trucks
  • Tow trucks
  • Utility service vehicles
  • TxDOT vehicles or other highway construction or maintenance vehicles
Handbook p. 52 ↗

You are required to:

  • Reduce your speed to 20 mph below the speed limit; or
  • Move out of the lane closest to the stopped vehicle, if the road has multiple lanes going the same direction

20 mph

How far below the speed limit you must slow if you can't move over

Handbook p. 52 ↗

Know the rule

Mail, delivery and trash-collection vehicles often stop in the roadway. Proceed with caution and, if possible, change lanes before safely passing them.

Handbook p. 52 ↗

You may not participate in:

  • A race
  • A vehicle speed competition or contest
  • A drag race or acceleration contest
  • A test of physical endurance of a vehicle's operator
  • An exhibition of speed or acceleration, or an attempt to set a speed record, tied to a drag race
Handbook p. 52 ↗

Know the rule

The criminal penalty for a street racing conviction ranges from a Class B misdemeanor to a second-degree felony. Racing on a public highway or street also brings a mandatory license suspension.

Handbook p. 52 ↗

Drag race

Two or more vehicles accelerating side by side to outdistance each other, or vehicles over a common course comparing speed or acceleration over a set distance or time.

Handbook p. 78 ↗

Race

Using vehicles to outgain or outdistance another vehicle or keep it from passing, to arrive somewhere first, or to test a driver's endurance over a long route.

Handbook p. 80 ↗

Put it into practice

On a two-lane highway posted at 65 mph, a tow truck is loading a car on the shoulder with lights flashing. You can't change lanes, so slow to 45 mph (20 below the limit) until you've passed it.

Check your understanding

Read the question, decide on an answer, then open it to check the explanation. These are Roadwise study questions based on the source handbook.

  1. Nothing unless it is a police or fire vehicle
  2. Slow to 10 mph below the limit and stay in your lane
  3. Stop completely until the vehicle leaves
  4. Move out of the closest lane or slow to 20 mph under the limit

Answer: Move out of the closest lane or slow to 20 mph under the limit

For a stopped TxDOT or similar vehicle with lights activated, move over or reduce speed by 20 mph below the limit.
