Are you concerned about excessive speeding in your fleet vehicles or by younger drivers? Speeding not only poses a significant safety risk, leading to potential accidents and citations, but it also negatively impacts your bottom line through increased fuel consumption, higher insurance premiums, and accelerated vehicle wear and tear. Rostra Accessories offers a straightforward and effective solution: Obd2 Speed Limiters.
The Problem of Uncontrolled Vehicle Speed
Uncontrolled vehicle speed is a widespread issue with serious consequences. For businesses managing fleets, speeding drivers can lead to:
- Increased accident risk: Speed is a major contributing factor in vehicle accidents.
- Higher fuel costs: Fuel efficiency decreases dramatically at higher speeds.
- Elevated insurance premiums: Speeding violations can lead to increased insurance costs.
- Vehicle wear and tear: Aggressive driving and high speeds accelerate vehicle depreciation and maintenance needs.
- Reputational damage: Accidents involving company vehicles can negatively impact brand reputation.
For parents of new drivers or individuals concerned about safe driving practices, the risks are equally significant.
The OBD2 Speed Limiter Solution
Rostra Accessories provides vehicle-specific speed limiting modules that connect seamlessly via the OBD2 port, offering a simple yet powerful way to manage maximum vehicle speed. These modules are pre-programmed to your desired speed limit and are designed to be tamper-proof, ensuring consistent speed control without driver interference.
Key Benefits of Rostra OBD2 Speed Limiters:
- Enhanced Safety: By limiting maximum speed, you significantly reduce the risk of speeding-related accidents.
- Improved Fuel Efficiency: Encouraging drivers to stay within set speed limits leads to substantial fuel savings.
- Reduced Vehicle Maintenance: Gentler driving at controlled speeds minimizes wear and tear, extending vehicle lifespan and reducing maintenance costs.
- Lower Insurance Costs: Demonstrating proactive speed management can potentially lead to lower insurance premiums for fleet vehicles.
- Peace of Mind: Knowing that vehicle speed is controlled provides peace of mind for fleet managers, parents, and anyone concerned about driver behavior.
- Versatile Applications: Ideal for a wide range of scenarios, including:
- Fleet Vehicles: Manage speed across your entire fleet to improve safety and reduce operational costs.
- New Drivers: Provide an added layer of safety for inexperienced drivers.
- Construction Sites & Low-Speed Zones: Enforce speed limits in areas with specific speed restrictions.
- Rental Cars: Maintain vehicle safety and control in rental fleets.
- School Zones & Residential Areas: Promote safer driving in sensitive areas.
- Parks and Recreational Areas: Ensure compliance with low speed limits in parks and recreational zones.
How Rostra OBD2 Speed Limiters Work
Rostra speed limiters are designed for easy integration and reliable performance. They function by intercepting the accelerator pedal signal once the pre-set speed limit is reached. This prevents the driver from accelerating further, effectively capping the vehicle’s maximum speed. The OBD2 connection simplifies installation, making it a convenient solution for various vehicle types.

Tamper-Proof Design for Reliable Speed Control
Once installed and programmed, Rostra speed limiters are tamper-proof. The set speed limit cannot be overridden or altered by the driver, ensuring consistent and reliable speed management. This feature is crucial for maintaining control and preventing unauthorized speed adjustments.
Cruise Control Considerations
For vehicles equipped with factory cruise control, Rostra offers an additional component to ensure complete speed limit enforcement. While the speed limiter restricts acceleration via the pedal, the cruise control system might allow drivers to exceed the set limit if engaged at a lower speed and then increased.
To address this, Rostra requires the installation of part number 250-3766 in conjunction with the speed limiter on vehicles with cruise control. This module disables cruise control functionality beyond the programmed speed limit, providing comprehensive speed management.

Selecting Your Rostra Speed Limiter System
Ordering the correct Rostra speed limiter for your vehicle is straightforward. Part numbers are based on the vehicle make, model, and desired speed limit. Simply specify the maximum speed you require when ordering.
Example Part Numbers for 2012-2020 Nissan NV Van:
- 250-9806-65: Limits speed to 65 MPH
- 250-9806-70: Limits speed to 70 MPH
