Road markings are essential for maintaining safety and order on the roads. They are used to convey important information to drivers, such as speed limits, warning signs, and traffic separation. These markings are applied using various methods, including paint, thermoplastic coatings, and raised markers, each with its own advantages in terms of durability and visibility. The colours and patterns used in road markings vary across different countries, but they all serve the same purpose of regulating traffic and preventing accidents. Understanding the meaning of these road markings is crucial for drivers to navigate safely and avoid hazards.

Road markings are painted using specialised trucks called stripers
Road markings are essential for providing guidance and conveying official information to drivers and pedestrians. These markings are commonly painted onto the road surface using specialised trucks called stripers.
These trucks, also known as road marking machines or pavement marking equipment, play a crucial role in enhancing road safety and efficiency. Stripers are designed to efficiently apply paint to the roadway surface, ensuring clear and consistent markings that are easily understandable by road users.
A typical striper truck features a large bed that accommodates hundreds of gallons of paint stored in huge drums. The paint is then run through a series of hoses under air pressure, allowing for precise application. The markings can be controlled manually or automatically by an operator seated on the bed of the truck.
One innovative example of a road marking truck is the RoadPrintz machine, featuring a robotic arm named Stella. This prototype truck can quickly and accurately paint various road symbols, such as turn arrows or "Bus Only" lanes, keeping workers safe and comfortable inside the air-conditioned truck cab.
In addition to traditional paint, specialised trucks may also utilise thermoplastic road marking paint. This solid powder is heated in a machine called a thermoplastic heater-mixer before being transferred to the paint tank of the truck. The molten coating is then applied to the road surface through a marking shoe, resulting in a thin and uniform layer of paint.

Yellow lines separate traffic moving in opposite directions
Yellow lines are used to separate traffic lanes going in opposite directions. They are usually painted on the road by a truck called a "striper". Yellow centre lines indicate that there is two-way traffic, flowing in opposite directions. A solid yellow line indicates that crossing it to overtake is not allowed. A single solid yellow line means that passing is not advised but that one may pass with extreme caution.
A single dashed yellow line means passing is allowed. A double solid yellow line means passing is not allowed from either direction. A double dashed line means passing is allowed only if there are no oncoming vehicles. A broken yellow line alongside a solid yellow line indicates that passing is permitted on the side of the broken line, but not on the side of the solid line. Double solid yellow lines mark the centre of the road and separate oncoming traffic.
In Norway, a double yellow line means that passing is forbidden in both directions. In the US, a double yellow line denotes a two-direction no-passing restriction, where traffic in both directions is prohibited from crossing the line to pass other traffic. In Ontario, it is legal to cross a single solid yellow line along a straight road if the vehicle is not within 30 meters of a bridge or railway crossing.
Botts' dots are another type of road marking, consisting of low, rounded white or yellow dots. They are used to mark the edges of traffic lanes and to draw drivers' attention to the road, such as to alert them to toll booths or school zones.

White lines separate traffic moving in the same direction
White lines painted on roads are used to separate traffic lanes moving in the same direction. They are usually applied right after the road has been paved by a truck called a "striper". These trucks contain hundreds of gallons of paint stored in huge drums. The markings are controlled manually or automatically by the controller who sits on the bed.
White lines can be solid or broken, single or double. Single white lines may also mark the right edge of the pavement. A broken white line separates two lanes travelling in the same direction. A solid white line marks the right edge of the roadway or separates lanes of traffic moving in the same direction. Crossing a solid white line requires special care and is discouraged. A double solid white line separates two lanes of traffic going in the same direction, and crossing it is prohibited.
White lines can also be used in conjunction with Botts' dots (low rounded white or yellow dots) to mark the edges of traffic lanes. Botts' dots are frequently used to draw the drivers' attention to the road, such as to alert drivers to toll booths, school zones, or significant reductions in the speed limit. They are usually only used in warm climates since snow ploughs typically remove them along with the snow.
In addition to lane separation, white lines are also used for stop lines, crosswalks, and parking spaces. Arrows are often used with white lines to show which turn may be made from the lane. If your lane is marked with a curved arrow and the word "ONLY", you must turn in the direction of the arrow. If your lane is marked with both a curved and straight arrow, you may either turn or go straight.

Botts' dots are low rounded white or yellow dots used to mark the edges of traffic lanes
Painted lines on roads are used for a variety of purposes, including separating traffic moving in the same or opposite directions, marking the edges of paved roads, and indicating passing rules. The colours used for these lines vary depending on the country and specific regulations.
In the context of these road markings, Botts' dots are low, rounded, white or yellow dots used to mark the edges of traffic lanes. They are named after California Caltrans engineer Elbert Botts, who invented the epoxy that keeps them glued to the road surface. Botts' dots are considered a type of mechanical non-reflective raised marker. They are frequently used in conjunction with raised reflective markers and are often found on highways and interstates as an alternative to painted lines.
Botts' dots are commonly used to enhance lane visibility in warm climates, as snow ploughs can remove them along with the snow. They are particularly useful in rainy conditions, where painted lines may become invisible. Botts' dots are also employed to draw drivers' attention to the road, alerting them to toll booths, school zones, or significant reductions in the speed limit.
In the United States, the use of Botts' dots and other road markings is legally regulated by the Federal Highway Administration's Manual on Uniform Traffic Control Devices. While they were once widely used in California, they have started to fall out of favour due to cost and worker safety concerns, as well as the need to accommodate self-driving cars.
Botts' dots have been adopted in various states with warm climates, including Hawaii, Alabama, Florida, Louisiana, Mississippi, Nevada, Georgia, Washington, and Texas. Some states with snowfall, such as Pennsylvania and Massachusetts, utilise Botts' dots temporarily during the summer months in construction zones.

Painted road symbols include turn-lane arrows or HOV lane markers
Painted road symbols, such as turn-lane arrows or HOV lane markers, are applied manually using stencils. Painted markings usually last 9 to 36 months. Some water-based paints can be applied at double the thickness of typical latex paints to extend the life of the markings.
HOV lanes are restricted traffic lanes where only vehicles with a certain number of occupants (usually two or more) are allowed to use. Some vehicles like buses, motorcycles, and low-emission vehicles are exceptions to the rule and can use the HOV lanes at any time. HOV lanes are marked with a white diamond symbol. Signs beside the lane will indicate what vehicles can use the lane.
Turn-lane arrows are often used in conjunction with other pavement markings, such as solid yellow lines, to indicate when it is safe to turn. A center lane with a regular broken yellow line and a solid yellow line on each side indicates a two-way left-turn lane. This lane is for traffic in either direction as part of a left-turn maneuver. The broken yellow line is inside the two-way left-turn lane, and the solid line is painted toward the adjacent traffic lane.
Other common road markings include Botts' dots, which are low, rounded white or yellow dots used to mark the edges of traffic lanes and draw drivers' attention to the road. Rumble strips are also used for this purpose and are a series of simple troughs ground out of the asphalt.
In addition to painted symbols, pavement markings such as solid yellow lines and double solid white lines divide lanes and indicate when it is safe to pass, change lanes, or stop. White lines separate traffic traveling in the same direction, while yellow lines separate traffic moving in opposite directions.
