When it comes to making a side-by-side street-legal, there are plenty of misconceptions out there. Some people think that if a side-by-side comes with a title, it’s already good to go for road use. Others believe that adding a few lights and mirrors will do the trick.
But here’s the reality: most side-by-sides can be made street-legal—but it’s not as simple as bolting on a few accessories and hitting the road.
Converting a side-by-side for street use requires meeting specific safety regulations, passing inspections, and installing the proper equipment. What’s required varies by state, making the process confusing and time-consuming.
While making a side-by-side street-legal is possible, many owners realize it’s more complicated than expected. That’s why the simplest and most hassle-free way to get it done is by letting Dirt Legal handle the paperwork for you.

All the Parts You Need to Make a Side-by-Side Street Legal
The final step in making your side-by-side street-legal is installing the necessary components to meet your state’s Department of Transportation (DOT) requirements. This takes both time and money, but ensuring compliance is crucial for operating on public roads.
Every state has different rules, so be sure to check your local laws before taking your side-by-side on the road.
Headlights
Most states require DOT-approved headlights, meaning they must:
Have both high-beam and low-beam functionality
Be operational at all times while the vehicle is running
Be visible without blinding oncoming drivers
To reduce power consumption, many side-by-side owners opt for LED headlights, which are more efficient and long-lasting than halogen bulbs. If your side-by-side doesn’t already have headlights that meet these standards, you’ll need to upgrade them.
Tail Lights and Brake Lights
A functional tail light and brake light are essential for visibility and safety. Most states require that the tail light remains on whenever the vehicle is running and that the brake light activate when the brakes are applied.
Some states also mandate that the tail light be powered by a battery capable of keeping it illuminated for a specific amount of time, even when the engine is off. Using an LED tail light can help reduce power draw and extend battery life.
Mirrors
Side-by-sides typically don’t come equipped with mirrors, but they’re required for street use in most states. Some states require two mirrors, while others allow just one.
There are several mirror options available:
Side mirrors: Provide the best visibility but may require mounting modifications.
Rearview mirrors: Some states accept a single rearview mirror in place of side mirrors.
Bar-end or small profile mirrors: These offer a minimalistic look while still meeting requirements.
Regardless of the type, a good mirror setup is essential for seeing traffic behind you.
Turn Signals
While some states allow hand signals, installing turn signals is a safer and more convenient option. They improve visibility, especially at night, and allow you to keep both hands on the wheel while signaling.
LED turn signals are a popular choice due to their low power consumption and long lifespan. Many kits come with easy plug-and-play wiring for quick installation.
Horn
A working horn is required for street-legal vehicles. Some states allow non-electric horns (like squeeze bulbs), while others specify that the horn must be electric.
The easiest solution is to install a small electric horn, which is inexpensive and easy to wire into your vehicle’s electrical system.
DOT-Approved Tires
Your side-by-side's stock tires may not be ready for street use. DOT-approved tires are required in most states and are designed to handle pavement safely.
Look for the "DOT" marking on the tire sidewall to ensure they’re certified for highway use. These tires provide better traction on paved surfaces and improve overall handling.
If you plan on doing a lot of street driving, consider a tire upgrade to improve durability and performance.
Windshield (Optional, Depending on State)
Some states require side-by-sides to have a windshield, while others allow riders to wear goggles or a helmet instead.
If your state requires one, a DOT-approved windshield is necessary. Options include:
Glass windshields: More durable but can be expensive.
Polycarbonate windshields: Lightweight and impact-resistant.
Many windshields come with wiper kits to improve visibility in bad weather.
License Plate Bracket and Light
A street-legal side-by-side must display a license plate, and some states have specific requirements for mounting and lighting.
To comply with regulations:
The plate must be securely mounted.
It must be clearly visible from behind the vehicle.
It must be illuminated at night by a small LED light.
Aftermarket plate brackets make it easy to securely mount your license plate in compliance with your state’s rules.
Upgrading the Electrical System to Make Any Side by Side Street-Legal
Most side-by-sides need additional electrical power to support street-legal accessories like turn signals, headlights, and horns. This often requires an upgraded stator, regulator/rectifier, or even an auxiliary battery.
Stator: Generates power for the vehicle’s electrical components. Upgrading it ensures enough power for lights and accessories.
Regulator/Rectifier: Converts AC power from the stator to DC power for stable output.
Battery: Some states require a battery to keep essential lights on when the engine is off.
Many aftermarket kits include everything needed for a seamless electrical upgrade.
Speedometer (Optional but Recommended)
A speedometer isn’t always required, but it’s useful for tracking speed, mileage, and fuel levels.
Some all-in-one digital displays include:
Speedometer
Odometer
Tachometer
Fuel gauge
Brands like Trail Tech offer plug-and-play speedometers that make installation simple.
Other Considerations
Parking Brake: Some states require a functional parking brake.
Seat Belts: If your side-by-side didn’t come with seat belts, they may be required for street use.
With the right modifications and paperwork, you can take your side-by-side from the dirt trails to the pavement. If you want to skip the hassle and ensure your vehicle is street-legal the right way, let Dirt Legal handle the process for you!
