a raised, rounded marker on a road used to guide traffic or mark lanes
A Botts' dot is a small, raised marker placed on the surface of roads to help drivers stay within their lanes. These markers are typically made of plastic and have reflective surfaces to make them visible at night or in low-light conditions. Botts' dots are usually arranged in rows along the centerline or lane markings of highways and roads. When a vehicle drives over them, they create a vibrating noise, alerting the driver if they are drifting out of their lane. They are often used in place of or alongside painted lane lines to provide additional guidance and improve road safety.
