1. What are Side by Side Street Legal Kits?
A side by side street legal kit is an assortment of components designed to make your off-road vehicle—like a UTV, SxS, or buggy—compliant with on-road regulations in many jurisdictions. These kits typically include items that are often mandatory for on-road use, such as turn signals, horns, mirrors, license plate brackets, and additional lighting solutions. Depending on where you live, there might be specific requirements you must meet to legally operate your UTV on public roads.
A street legal kit is not a one-size-fits-all solution; different states, counties, and municipalities can have unique regulations. Yet, most kits share common parts that upgrade your side by side so that it mimics the functionality of a standard passenger vehicle. By installing side by side street legal kits, you can potentially transform your off-road machine into a dual-purpose vehicle—ideal for both public roadways and your favorite trails.
2. Why You Need a Street Legal Kit
Having side by side street legal kits provides numerous advantages. Here are some of the top reasons to invest in one:
2.1 Convenience
The convenience of being able to drive your UTV from your home to the trailhead without the need for a trailer or truck is a huge perk. If you frequently ride in areas where off-road trails connect with paved roads, having a street legal kit saves you time, hassle, and money in the long run.
2.2 Safety
Street legal kits equip your UTV with essential safety features such as mirrors, turn signals, and adequate lighting. These modifications help you remain visible to other drivers on the road, reduce the risk of accidents, and give you better awareness of your surroundings.
2.3 Legal Compliance
Operating an off-road vehicle on public roads without the required accessories can lead to hefty fines or legal issues. By installing the correct kit, you’ll be meeting local regulations and ensuring that you and your passengers stay on the right side of the law.
2.4 Increased Resale Value
A side by side street legal kit can make your UTV more appealing to prospective buyers. When it’s time to sell or trade in, a ready-to-drive SxS for both off-road and on-road adventures stands out from the competition.

3. Components of a Quality Side by Side Street Legal Kits
While kits can vary by brand, price, and specific local requirements, most side by side street legal kits share several essential components. When shopping around, make sure your kit includes the following features:
3.1 Turn Signal System
A fully functioning turn signal system is often at the heart of any street legal kit. Turn signals allow you to communicate your intentions to other drivers on the road, which is crucial in preventing accidents and meeting road rules. This system often includes:
- Front and rear turn signals
- Signal relay module
- Indicator lights on the dashboard
3.2 Horn
A horn is another standard requirement in many regions. An electric horn, mounted near the driver’s seat or on the dash, is typically activated through a simple button or switch. It’s essential for alerting drivers, pedestrians, or fellow off-road riders to your presence.
3.3 Mirrors
Rearview mirrors and side mirrors help maintain situational awareness on busy roadways. Mirrors are crucial, not just for legal reasons, but also for enhancing safety. Many states require at least two mirrors, although regulations can differ.
3.4 License Plate Holder and Light
A dedicated license plate bracket that can be affixed to the rear (and sometimes front, depending on local laws) of your UTV is a must. In many areas, it’s also mandatory to have a light illuminating the plate so it is visible at night.
3.5 Additional Lighting Upgrades
Depending on regulations, you might need to upgrade your UTV’s headlights to DOT-approved headlights or add certain reflective or illuminated features. This is especially relevant if you plan to drive at night or on busy roads. Sometimes, you’ll need additional brake lights or improved tail lights for higher on-road visibility.
3.6 Speedometer or Odometer
While not always required, having a clear speed indicator can help you comply with speed limits and track your mileage. Some kits may include a speedometer or odometer specifically designed for a side by side.
3.7 Parking Brake and Safety Equipment
In certain regions, a functional parking brake and additional safety items—such as reflectors or a windshield—might be required. Make sure you check your local laws to see which of these safety features are necessary.
4. Legal Considerations: What You Must Know
Before installing your side by side street legal kit, you need to understand your area’s specific regulations and laws. Here are some factors to keep in mind:
- State and Local Laws: In many states, laws pertaining to street-legal UTVs differ from county to county or even city to city. Always start by researching the legal requirements in your specific jurisdiction.
- Minimum Age Requirements: Some places may require drivers to have a valid driver’s license. Additionally, there could be age restrictions for passengers.
- Insurance and Registration: Certain states demand that UTVs be insured and registered similarly to cars and motorcycles. You might have to carry proof of insurance and display registration decals or license plates.
- Maximum Speed Limits: Some streets or highways may have restrictions on the speed a UTV can legally travel. Ensure your vehicle can adhere to these speed limits.
- Emissions Testing: In states with strict emission regulations, you might have to pass an emissions test or comply with specific exhaust standards.
Pro Tip: Always consult the Department of Motor Vehicles (DMV) or relevant local authority websites, or speak directly to a representative, to fully comprehend the requirements for making your UTV street legal. Ignorance of the law often leads to costly fines or impounding of your vehicle.
5. How to Choose the Right Side by Side Street Legal Kits
Choosing the best side by side street legal kit is a critical step toward enjoying your UTV on public roads. To make an informed decision, keep these points in mind:
5.1 Brand Reputation and Reviews
Start by researching brands known for producing reliable, high-quality kits. Look for online reviews on enthusiast forums, retailer websites, and social media groups where real-world users share experiences with these kits. A well-established brand with a history of satisfied customers generally delivers better quality products and support.
5.2 Compatibility
Different UTV models come with distinct wiring systems, mounting points, and body shapes. Ensure the kit you’re looking at is compatible with your exact side by side model and year. Some kits are designed specifically for popular models like the Polaris RZR, Can-Am Maverick, Yamaha YXZ, Honda Talon, or Kawasaki Teryx.
5.3 Ease of Installation
Depending on your mechanical skillset, you might want a kit that is easier to install. Some kits come with “plug-and-play” wiring harnesses, pre-drilled mounting brackets, and detailed, illustrated instructions. Others might require more advanced mechanical and electrical expertise. If you’re not comfortable handling complex wiring or drilling holes, consider hiring a professional or looking for a more straightforward kit.
5.4 Customer Support and Warranty
When selecting a street legal kit, it’s beneficial to opt for manufacturers who provide responsive customer service and a solid warranty policy. Should any part fail or if you face installation issues, you’ll want immediate assistance. A trustworthy brand typically offers a one-year or even a lifetime warranty on certain components.
5.5 Price
Street legal kits can range significantly in cost. The old adage “you get what you pay for” often rings true: cheaper kits might cut corners on material or component quality, leading to issues down the line. While it might be tempting to go for the cheapest option, investing in a high-quality kit could save you money and headaches in the long run.

6. Installation Process: A Step-by-Step Guide
While the exact steps for installing a side by side street legal kit can vary between brands and models, here is a general outline to help guide you:
Step 1: Read the Instructions Thoroughly
Before doing anything, read through the entire installation manual or watch tutorial videos provided by the kit manufacturer. Take note of any specialized tools required and ensure you have everything on hand.
Step 2: Disconnect the Battery
For safety and to prevent electrical shorts, disconnect the negative battery terminal before you begin. This is a fundamental practice whenever you work on a vehicle’s electrical system.
Step 3: Mounting the Turn Signals
Identify where your kit instructs you to install the front and rear turn signals. Often, manufacturers provide templates or drilling guides to help you drill holes in the body panels. Once you attach the turn signals, run the wiring harness to the fuse box or designated power source, securing the wires with zip ties along the way.
Step 4: Installing the Relay, Flasher, or Control Module
Many turn signal systems include a module that controls the blinking rate and ensures the signals function correctly. Follow the wiring diagram to connect the module to the signals, horn, and any indicator light on the dashboard.
Step 5: Mounting the Horn
Choose a convenient location to mount the horn, often near the front of the vehicle to maximize sound projection. Ensure you follow the kit instructions regarding wiring polarity. Typically, you’ll connect one wire to the power (through a fuse) and the other wire to a horn switch.
Step 6: Attaching Mirrors
If the kit includes side mirrors, place them on the roll cage or the doors, ensuring the driver has an unobstructed view. A center rearview mirror typically mounts on the inside or top portion of the roll cage.
Step 7: License Plate Bracket and Light
Install the license plate bracket in a location visible from the rear. Make sure you run wiring for the license plate light if required. Some kits have an LED light that hooks into the tail light power wire.
Step 8: Connect the Battery and Test
Once all components are installed, reconnect the battery and test each element systematically:
- Turn signals (left and right).
- Horn function.
- Mirrors (angle them correctly for rearward visibility).
- License plate illumination.
- Any other features included in the kit.
Step 9: Final Adjustments and Documentation
Use the instructions to troubleshoot any issues and make final adjustments to angles or wiring. Keep any purchase receipts, part numbers, and warranties in a safe place in case of future problems or if you need to verify legal compliance.
7. Maintenance Tips for Your Side by Side Street Legal Kits
A properly installed side by side street legal kit needs routine upkeep. Here are some tips to help preserve the functionality and durability of your kit:
- Regularly Inspect Lights and Signals: Check all bulbs, LEDs, and wiring connections every few rides. Vibration and off-road conditions can loosen connections or damage wiring.
- Clean Mirrors and Reflectors: Mud, dust, and debris can accumulate on mirrors or reflective surfaces. Keep them clean to maintain optimal visibility.
- Monitor Wiring Harness: Ensure all wires are secure and free from fraying or pinching. Off-road conditions can be harsh, so occasional wire re-checks are wise.
- Test the Horn: A failing horn might just need a new fuse or a small adjustment to its wiring connections. Test it periodically, particularly before rides where you plan on hitting public roads.
- Check Fasteners and Mounting Bolts: Vibrations can loosen bolts for mirrors, horns, or turn signals. Occasionally tighten them to the manufacturer’s specified torque.
