Vienna Convention traffic signal ahead (white triangle) These warning signs indicate that traffic lights are ahead, and are often used when it is difficult to see that a traffic light may already be showing red, to warn a driver to prepare to slow down. They may be supplemented with flashing light or lighted sign when light is red or turning red.
Local traffic road signs usually employ black text on white. Exceptions are the Czech Republic (yellow-on-black), Finland (white-on-black), Austria and Spain (white-on-green), as well as Denmark, Iceland and Poland (blue-on-white).

Almost all prohibitory signs use a red circle with a slash. Restrictive signs typically use a red circle, as in Europe. Some may be seated on a rectangular white background.
