Off-road vehicle sports can be roughly divided into: 1. Track race; 2. Rally race; 3. Assembly race; 4. Urban track race; 6. Desert cross-country race and other races. Here are the details of each race The venue requirements for the event are as follows:

1. Field race; it is a track within 2 kilometers, with more than 18 obstacles designed to imitate various road conditions in nature.

2. Rally; Category 1 rally (RALLY OF THE FIRST CATEGORY): refers to a race on the road with a given mandatory average speed. The race road is completely or partially connected with ordinary traffic routes. Connected. All vehicles in the rally execute the same schedule (ITINERARY), or first converge to the same pre-set race point according to several different schedules, and then execute the same schedule. A race can include one or several special stages and driving sections.

3. Assembly race; a car race on an unsealed public road in compliance with national traffic regulations, driving according to the prescribed time and route, and not for the purpose of racing.

4. City competition; it is an 800-meter track formed on a site of the same size as a standard basketball court using steel structures or city steps such as piles of sand and gasoline tanks.

1. Track race; it is a track within 2 kilometers, with more than 18 obstacles designed to imitate various road conditions in nature.

2. Rally: It is a multi-day, segmented long-distance bus race held within a country or across national borders. The race surfaces range from flat asphalt roads to rugged mountain roads in the wilderness. During the competition, the route will not be blocked from other vehicles, and the daily distance traveled and arrival time of participating cars will be limited. Checkpoints are set up on the route to check whether the vehicle is passed within the specified time. This is a competition that not only tests the performance and quality of the vehicle, but also tests the driver's skills. The participating cars must be mass-produced cars or modified cars. Short rallies take a few days, long ones can last dozens of days. The rally divides the distance from the starting point to the finishing point into several driving sections and stages, with food stations and rest stops along the way. When driving on road sections, participating cars are subject to certain speed limits and must arrive at the end of each road section within the specified time. They cannot advance or lag behind. They must abide by local traffic rules while driving. Those who violate the rules will be deducted points. During the stages, the cars can travel at full speed, sometimes reaching speeds of more than 200 kilometers per hour. At the end of the entire rally, the car and driver with the least cumulative time and the fewest points deducted from the entire rally will be the winner.

The first official car rally was held in Britain in 1900, with a total length of more than 1,600 kilometers. The longest distance was the rally from London, England to Sydney, Australia, held in 1977. The entire journey was more than 31,100 kilometers long and took 46 days.
