Yes—you can make a go kart street legal in most U.S. states, provided it meets low-speed-vehicle rules, passes inspection, and carries insurance. This guide walks you through every step, from bolting on headlights to collecting your license plate, so you can enjoy the thrill of karting without staying stuck on private tracks.

What “Street Legal” Really Means
“Street legal” is a shorthand for “complies with federal and state motor-vehicle safety standards.” In practice, a go kart must either (a) be re-classified as a Low-Speed Vehicle (LSV)—capped at 25 mph—or (b) meet your state’s custom-vehicle code. Nearly every state now recognises LSVs and allows them on roads posted 35 mph or below.
Minimum Federal LSV Rules
- Top speed: 20–25 mph
- 4 wheels, GVWR < 3,000 lb
- VIN & 17-digit label
- DOT-approved lighting and seat belts
States then layer extra rules—usually mirrors, a horn, and insurance—on top.
Quick Checklist of Street-Legal Essentials
| Item | Why It Matters |
|---|---|
| Headlights, tail-/brake lights, turn signals | Visibility day & night |
| DOT-approved tires & fenders | Grip + sprays containment |
| Mirrors (left, right, centre) | 180° rear view |
| Horn (audible 200 ft) | Alert traffic & pedestrians |
| Seat belts | Required for all LSVs |
| Windshield + wiper | Protection from debris & rain |
| Speedometer/odometer | Confirms you stay under 25 mph |
| VIN plate & registration sticker | Legal identity for inspections |
Step-by-Step: How to Make Your Go Kart Street Legal
1 Check Local Codes and Vehicle Class
Start at your state Department of Motor Vehicles (DMV) site. Search for “low-speed vehicle,” “neighborhood electric vehicle,” or “custom vehicle.” Note speed caps, lighting standards, and whether gas-powered karts qualify—some states only accept electric drivetrains.
Tip: Call the inspection office before you spend money; some jurisdictions refuse karts outright.
2 Add Mandatory Safety Equipment
Install or upgrade:
- Lighting kit—headlights (hi/lo), turn indicators, tail and brake lights.
- Mirrors—two external plus interior.
- Horn—wired to steering column.
- Seat belts—three-point belts for every seat.
- Windshield & single wiper—plexiglass is fine if DOT-marked.
These parts can be ordered in a single “street-legal kit” for $400–$800 and take a weekend to fit.
3 Fit DOT Tires and Wheel Guards
Standard slicks are not road-rated. Swap to DOT-approved tires and add fenders that cover at least half the wheel-top to block debris.
4 Verify Speed and Power Limits
Use a GPS app to confirm your kart can’t exceed 25 mph on level ground. Gearing changes or an electronic governor may be needed. Exceeding the cap pushes you into “motorcycle” or “custom vehicle” territory—harder and pricier to license.
5 Get a VIN, Title, and Registration
If your frame lacks a VIN, apply for a state-assigned VIN. You’ll show:
- Bill of sale or proof of origin
- Photos of the finished kart
- Completed safety-feature checklist
After inspection, the DMV stamps a VIN, issues a title, and provides a temporary tag. Fees run $45–$120.
6 Carry Liability Insurance
Most insurers group street-legal go karts with ATVs or kit cars. Minimum bodily-injury cover is usually $25k/$50k, plus property damage. Expect $150–$400 per year—cheaper if you bundle with auto.
7 Pass Final Safety Inspection & Collect Plates
Bring the kart, receipts, VIN paperwork, and proof of insurance. Inspectors test lights, horn, brakes, and top speed. Once approved, you’ll get:
- Permanent plate (full-size or motorcycle size, depending on state)
- Registration sticker (renew annually)
Congratulations—your go kart is now officially street legal and ready for low-speed roads!

Frequently Asked Questions
Can I drive a street-legal go kart on the highway?
No. Even as an LSV, you’re limited to roads posted 35 mph or less. Anything faster is off-limits for safety reasons.
Does my kart need emissions testing?
- Gas-powered karts may need a simple tail-pipe test in California and a few other states.
- Electric karts are exempt everywhere.
Check your county’s DMV site to be sure.
What about homemade electric go karts?
Electric builds often cruise through inspection because they’re zero-emission and quieter. You still need lights, belts, and mirrors, plus a top speed under 25 mph.
Common Mistakes to Avoid
- Skipping the VIN. A “serial number” on the chassis is not a legal VIN.
- Over-gearing. If an inspector clocks you at 28 mph, you fail.
- Ignoring weight limits. Adding a roll cage and large batteries could push you over the 3,000-lb LSV ceiling.
- Forgetting the horn. It’s the most overlooked item in DMV checks.
- Riding at night without the right lights. Two front lights plus tail and brake lights are mandatory after dusk.
Final Thoughts: Is It Worth Making a Go Kart Street Legal?
If your daily errands stay on 35-mph streets and you love open-air driving, a street-legal go kart can be a fun, eco-friendly runabout. Startup costs hover around $1,000, but insurance and registration are minimal compared to a car. Just remember:
- Research your state’s rules first.
- Keep the kart under 25 mph.
- Document every part you install.
Do that, and you can make a go kart street legal without headaches—and turn every grocery run into a mini-Grand Prix.
