Other alternatives, similar to the Botts' dots, use raised strips, painted or glued to the surface.

A rumble strip can be a series of simple troughs, typically 1 cm (0.4 in) deep and 10 cm (4 in) wide, that is ground out of the asphalt. Rumble strips are commonly used for the same purpose.They are normally only used in warm climates since snow plows usually remove them along with the snow.

They are frequently used in this way to alert drivers to toll booths, school zones or other significant reduction of speed limit. Botts' dots are also used across a travel lane to draw the drivers attention to the road. Generally they are used to mark the edges of traffic lanes, frequently in conjunction with raised reflective markers.

Botts' dots (low rounded white or yellow dots), named for the California Caltrans engineer Elbert Botts, who invented the epoxy that keeps them glued down, are one type of a mechanical non-reflective raised marker.

The lenses are available in a variety of different colors, mainly white, yellow/orange, green, red, and blue. This provides protection from snow plowing and allows the lenses to be self-cleaning-they pass a rubber blade when depressed. The housing is mounted within a cast iron shoe, which the rubber housing sinks in to when driven over. They consist of four reflective lenses mounted in a durable white rubber housing, two facing fore and two facing aft.

Cat's eye, invented by Percy Shaw in the 1930s, Cat's eyes equip many major routes in the British Isles.

Mechanical devices may be raised or recessed into the road surface, and either reflective or non-reflective. White raised pavement marker near "pea-structure" side-line on highway surface

Today, road markings are used to convey a range of information to the driver spanning navigational, safety and enforcement issues leading to their use in road environment understanding within advanced driver-assistance systems and consideration for future use in autonomous road vehicles.

There is continuous effort to improve the road marking system, and technological breakthroughs include adding retroreflectivity, increasing longevity, and lowering installation cost. Road surface marking can also indicate regulations for parking and stopping. They can be used to delineate traffic lanes, inform motorists and pedestrians or serve as noise generators when run across a road, or attempt to wake a sleeping driver when installed in the shoulders of a road.

However, countries and areas categorize and specify road surface markings in different ways-white lines are called white lines mechanical, non-mechanical, or temporary. Uniformity of the markings is an important factor in minimizing confusion and uncertainty about their meaning, and efforts exist to standardize such markings across borders. Road surface markings are used on paved roadways to provide guidance and information to drivers and pedestrians. In some countries and areas (France, Italy, Czech Republic, Slovakia etc.), road markings are conceived as horizontal traffic signs, as opposed to vertical traffic signs placed on posts. They can also be applied in other facilities used by vehicles to mark parking spaces or designate areas for other uses. Road surface marking is any kind of device or material that is used on a road surface in order to convey official information they are commonly placed with road marking machines (also referred to as road marking equipment or pavement marking equipment).
