Off-road vehicle facts for kids
An off-road vehicle is a special type of vehicle that can drive well on and off regular roads. This means it can handle rough ground, dirt paths, and even no roads at all! These vehicles usually have big tires with deep patterns for extra grip. They also have a flexible suspension system to absorb bumps.
It's important not to confuse off-road vehicles with off-highway vehicles. Off-highway vehicles are built only for very wild places. They are not meant for regular highways. They can travel over really tough land like swamps, ice, or deep snow.

Why Off-Road Vehicles Are Popular
Off-road vehicles are very popular because they can be used for many different things. They are super versatile! Many types of motorsport involve racing off-road vehicles.
The three biggest types of off-road races for 4-wheel vehicles are:
- Mud racing
- Desert racing
- Rockcrawling
Most people use these vehicles to explore places far from paved roads. Their high clearance (how high the vehicle is off the ground) and strong traction help them drive on rough trails and forest roads. These paths often have uneven surfaces and little grip.
What is Rockcrawling?
Rockcrawling is an extreme type of off-road driving. Drivers use vehicles, from regular ones to highly modified ones, to get over big obstacles. These obstacles are usually large rocks.
In rockcrawling, drivers use powerful four-wheel drive vehicles. These can be trucks, Jeeps, or special "buggies". They drive them over very difficult terrain. This includes places like boulder fields, mountain foothills, and rocky trails.
Rockcrawling is all about driving slowly and carefully. Rock crawlers often go up, down, and across obstacles that seem impossible to cross. Most vehicles used for rock climbing are 4x4s.
Rockcrawling competitions happen at local and national levels. A competition usually has obstacle courses about 100-200 yards long. Each obstacle is marked with gates, much like a ski course.
Driving Responsibly: Tread Lightly!
In the United States and other places, off-road vehicles should only be driven on roads, trails, and areas that are officially open for off-road travel.
The United States Forest Service asked an organization called Tread Lightly! to create a program. This program, called "RIDE ON", reminds off-road drivers to "RIDE ON Designated Routes". This helps stop people from driving wherever they want on public lands.
Most US states and other government groups have similar laws and regulations. These rules help protect the environment. Tread Lightly!'s main message is to stay on existing roads or trails. This also helps prevent problems between different groups of people. It stops entire areas from being closed to off-road driving.
