Q Is Caltrans planning to remove Botts dots?
.  
A.

Let us assure you that there are no immediate plans to get rid of Botts' Dots. Caltrans is simply experimenting with different types of striping that shows promise for providing better visibility, durability and, yes, providing a tell-tale thump under tires to warn motorists if they drift out of their lane. It was experiments such as these that led to the development of Botts' Dots in the 1950s, and we are always looking for ways to do things better and safer. The bottom line is that for a vast majority of highway applications, Botts' Dots are here to stay.
