Question 6919
What is the function of the rumble strips located on the right edge of the roadway, normally placed on the shoulder or coinciding with the pavement marking that delimits the right lane?
- To alert the driver if the vehicle strays from the path of its lane.
- To indicate the existence of a special lane or one reserved for certain vehicles.
- To mark the edge of the roadway, especially in low-visibility conditions.
Show answer and explanation
Correct answer: To alert the driver if the vehicle strays from the path of its lane.
The rumble strips along the right edge make your car vibrate and produce noise when you drive over them, warning you that you are unintentionally drifting out of your lane, for example because you are distracted. If you hear them, steer gently back on course. They do not serve as edge markers or separate a special lane.
