Which types of vehicles are allowed to use flashing lights?

In Texas, the use of flashing lights is primarily reserved for vehicles that require heightened visibility due to the nature of their operations or the situations they may encounter. Emergency vehicles, such as police cars, ambulances, and fire trucks, utilize flashing lights to alert other road users to their presence, indicating that they may be responding to an emergency and need the right of way.

Farm tractors also need to have flashing lights to enhance visibility, especially during operations on public roadways. These vehicles often operate at slower speeds than typical traffic and might be in unusual positions on the road, making their visibility crucial for the safety of both the operator and other motorists.

While snow removal equipment and school buses may also use flashing lights, the specific question focuses on the types authorized broadly under state regulations, and so the inclusion of farm tractors alongside emergency vehicles encapsulates two essential categories recognized for their specific needs for flashers.
