Drivers need to be informed when they are approaching train tracks with railroad crossing signs so that they can be prepared to slow down and stop.

One of the most helpful types of highway signs for long distance travelers is the guide sign, which directs drivers to specific locations.

Interstate signs are designed to remind drivers the route they are on and the direction they are headed, which is essential information for all motorists.

Pavement marking can make streets safer, as they add extra clarity to the directives that motorists read from signs while driving.
