Question 6916
What is the purpose of the rumble strips located along the center of the roadway that, through vibration and sound, warn the driver if they drift out of their lane's path due to distraction?
- To mark the sections of road where passing is prohibited.
- To improve the visibility of the lines separating traffic traveling in opposite directions.
- To reduce head-on collision accidents on two-way roads.
Show answer and explanation
Correct answer: To reduce head-on collision accidents on two-way roads.
Rumble strips in the center of a two-way road make your car vibrate and produce noise when you unintentionally drift out of your lane, for example because you are distracted. This helps you correct your path before entering oncoming traffic, so their main purpose is to reduce head-on collisions. They do not mark where passing is prohibited; the lines and signs do that.
