Other markings include in the cities, destination and exit names painted in the lanes, which is done due to the very close proximity of exits, where in many cases it would be impractical to put up many overhead signs, although these are often seen approaching exits, a curved or slanted arrow points to the side of the expressway the exit will be on. A straight arrow following characters indicates the destination of the expressway. 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. [1] Mechanical markers [ edit ] The cat's eye, showing the iron base, rubber housing and lenses White raised pavement marker near "pea-structure" side-line on highway surface A double yellow line (commonly known as just a "Double Yellow") next to the curb means that no parking is allowed at any time, whilst a single yellow line is used in conjunction with signs to denote that parking is restricted at certain times. Double and single red lines mean that stopping is not allowed at any time or between certain times respectively. Cat's eye, invented by Percy Shaw in the 1930s, Cat's eyes equip many major routes in the British Isles. They consist of four reflective lenses mounted in a durable white rubber housing, two facing fore and two facing aft. The housing is mounted within a cast iron shoe, which the rubber housing sinks in to when driven over. This provides protection from snow plowing and allows the lenses to be self-cleaning—they pass a rubber blade when depressed. The lenses are available in a variety of different colors, mainly white, yellow/orange, green, red, and blue.

Almost all countries in North and South America have solid and intermittent yellow lines separating traffic directions. However, Argentina and Uruguay have intermittent white lines separating traffic when overtaking is permitted from both directions, and solid yellow lines when overtaking is prohibited from both directions; when overtaking is permitted from only one direction, such countries separate traffic with a combination of white and yellow lines. Chile usually uses white lines only, except when snowy conditions are possible (in the South and on mountain roads). Then all lines are yellow. Venezuela uses white lines.

In California and Nevada, Botts' dots when present are usually the lines, and no paint is used for additional markings. Exceptions include: freeways built from white concrete where painted stripes are added to make the lanes more visible through sun glare, freeways built so wide that the risk of drifting out of lane is minimal (e.g., Interstate 5 in the Central Valley), and freeways in areas where it snows in the winter (since the snowplows would scrape off the Botts' dots). Installing In Colder Weather?If you're applying the paint to a concrete surface or using a primer it's important to give the primer at least an hour to cure before applying the paint over the top. This paint should not be applied if the air temperature or surface temperatures are bellow 5°C Applying Paint Over Current Lines?

In general European countries follow the Vienna Convention on Road Signs and Signals, which describes what road signs and road markings shall look like. The convention has some flexibility so road markings vary somewhat between the countries. Burning: High heat and flame can be used as methods of marker removal. In the hot-compressed air method, a combustion chamber with a mixture of high-velocity air and propane can emit heated gas with temperatures of 2,400°F (1,320°C). An excess-oxygen method uses propane and oxygen mixture ejected out of a nozzle to create an external flame and additional oxygen is added to the flame to create temperatures in excess of 4,500°F (2,480°C). The flame is applied directly to the markers. In both methods, care is to be taken not to melt the asphalt road surface. Julian, Frank & Moler, Steve (July–August 2008).

In general, white lines separate traffic in the same direction, single broken lines mean passing or lane changing is allowed, single solid white lines mean lane changing is discouraged or prohibited, and double solid white lines mean it is prohibited, [51] as it often is in tunnels. On two-lane roads, a single broken center line means that passing is allowed in either direction, a double solid center line means passing is prohibited in both directions, and the combination of a solid line with a broken line means that passing is allowed only from the side with the broken line and prohibited from the side with the solid line. [51] Lanes with double broken yellow lines on each side are reversible, [52] and lane control signals are used to indicate which direction traffic in such lanes is supposed to travel. The solid white line on the right side is called the 'fog line' used to help cars stay in their lane during foggy conditions and help pedestrians stay off the road. Yellow double solid line: no parking and stopping all day. These are used near an intersection, the crosswalk, or a bus station.

However, some local governments allow parking at particular times. The time available for parking is written on a sign. In the United States, the first documented use of a painted center line was in 1911 along Trenton's River Road in Wayne County, Michigan. [29] According to the state of Michigan, the idea of using a painted center line was conceived in 1911 by Edward N. Hines, the chairman of the Wayne County, Michigan, Board of Roads, [30] after watching a leaky milk wagon leave a white trail along a road. [31] Hines was the fifth recipient of the George S. Bartlett Award for Highway Progress, [32] and was inducted posthumously in 1972 into the Michigan Transportation Hall of Honor for his innovation, and was honored in 2011 with the first Paul Mijksenaar Design for Function Award.
