Thailand is widely acknowledged as having the most extensive road transportation network in all of Southeast Asia with more than 390,026 kilometers, of which 384,176, or 98.5%, is concrete or asphalt paved, and 66,266 km forming a national highway network connecting each region of the country as you can see in Thailand roads map. The Department of Highways has developed the concept of a 20-year Intercity Motorway Development Master Plan for the period 2017 – 2036, comprising 21 routes with a total length of 6,612 km. The Greater Mekong area road network already includes a southern economic corridor inclusive of Thailand, Cambodia and Vietnam; the east-west economic corridor linking Myanmar, Thailand, Laos and Vietnam; the north-south economic corridor which runs from southern China through Laos and Myanmar, and into Thailand; and the southern coastal economic corridor also connecting Thailand, Cambodia and Vietnam. All major cities in Thailand are accessible by land, with all-weather highways and intercity roads linking them to the road network covering the whole country, as well as the Asian Highway and the road networks of neighboring countries at border crossings.

DORR rural roads do not follow the regional numbering scheme in Thailand. Signs are gold-on-blue, with a two-letter province designation prefixed to the road number. Depicted is YS.4011, for a rural road in Yasothon Province as its shown in Thailand roads map. The rural road network measures some 35,000 km, about 82 percent of which is paved. The Department of Rural Roads of the Ministry of Transport takes care of the maintenance of all the rural roads in Thailand. DORR milestones show the kilometer number, and the edges may show distances remaining to the next two villages. File:KM3-YT 3.JPGOlder roads built by the Ministry of the Interior Public Works Department (กรมโยธาธิการ กระทรวงมหาดไทย) have only department insigne and kilometer number, and do not show distances on their edges.

The Thai motorway network is small. Coupled with Bangkok extensive expressway network, the motorways provide a relief from regular traffic in Bangkok. The Thai Government is planning infrastructure investment in various "megaprojects", including motorway expansion to approximately 4,500 kilometers as its mentioned in Thailand roads map. Thailand uses the expressway term for the toll road or highway network. Most of expressways are elevated with some sections on the ground level. The current expressway network covers major parts of Bangkok and suburban areas. Expressways are used to avoid heavy traffic jams in Bangkok and reduce traffic time, but are sometimes congested in rush hour.

The Thai highway network follows the left-hand traffic rule of the road. The network is the twin responsibility of the Department of Highways (DOH, Thai: กรมทางหลวง, Krom Thang Luang), and the Department of Rural Roads (DORR, กรมทางหลวงชนบท, Krom Thang Luang Chonnabot), under the oversight of the Transportation ministry of Thailand. Public highways (ทางหลวง, thang luang) are also called public roads (ถนนหลวง, thanon luang), especially when part of urban streets. The network spans over 70,000 kilometers across all regions of Thailand as you can see in Thailand highway map. Most are single carriageways. Dual carriageways have frequent u-turn lanes and intersections slowing down traffic. Coupled with the increase in the number of vehicles and the demand for a limited-access motorway, the Thai Government issued a Cabinet resolution in 1997 detailing the motorway construction master plan. Some upgraded sections of highway are being turned into a "motorway", while other motorways are not being built from highway sections. See Thai motorway network.

The 1992 Highway Act (Thai: พระราชบัญญัติทางหลวง พ.ศ. 2535), revised as the 2006 Highway Act (Thai: พระราชบัญญัติทางหลวง (ฉบับที่ 2) พ.ศ. 2549), defines the following five highway types: A special highway (Thai: ทางหลวงพิเศษ) or motorway is a high capacity highway designed for high speed traffic, for which the Department of Highways carries out construction, expansion, upkeep and repairs, and is registered as such. Motorway entrances and exits have controlled access, and controlled by the DOH as its mentioned in Thailand highway map. Registration of motorways is overseen by the Director General of the DOH. A national highway (Thai: ทางหลวงแผ่นดิน) is a primary highway, part of the network connecting regions, provinces, districts, and other important destinations, for which the DOH carries out construction, expansion, upkeep and repairs. Registration of national highways is overseen by the Director General of the DOH.

A single digit number indicates one of the major highways connecting Bangkok to outlying regions as its shown in Thailand highway map: Route 1 (Phahonyothin Road), Northern Thailand, route 2 (Mittraphap Road), Northeastern Thailand, route 3 (Sukhumvit Road), Eastern Thailand, route 4 (Phetkasem Road), Southern Thailand. A two-digit number indicates a main highway for a particular region. The first digit of a highway number indicates the region of Thailand it primarily services: Highways beginning with 1 are in northern Thailand, highways beginning with 2 are in northeastern Thailand, highways beginning with 3 are in central and eastern, as well as the upper south, highways beginning with 4 are in southern Thailand. For example, Route 22 is a main highway in the northeast that runs between Udon Thani and Nakhon Phanom. A three-digit number indicates a secondary highway. A four-digit number indicates an intra-province highway connecting the provincial capital to the districts, or to important sites in the province.
