What are the horizontal white lines that warn motorists of traffic hazards called?

The correct answer relates specifically to features designed to alert drivers of potential dangers on the road. Rumble strips are textured grooves or raised patterns placed on roadways, typically at strategic locations such as intersections or before transitions in road conditions. They serve a crucial purpose: when vehicles drive over them, they produce a rumbling sound and vibrations, effectively warning drivers to pay closer attention and reduce speed due to an upcoming hazard.

This design enhances safety by providing an auditory and tactile warning, which is particularly beneficial in preventing accidents. Rumble strips are widely recognized as an important traffic safety measure, especially in areas where driver inattention is a significant risk.
