Excessive speed is a major concern for fleet managers and vehicle owners alike. Speeding not only increases the risk of accidents and traffic violations but also leads to higher fuel consumption, increased vehicle wear and tear, and potentially inflated insurance premiums. If you’re looking for a robust solution to manage vehicle speed and promote safer driving habits, Obd2 Speed Limiters offer an effective answer.
Rostra Accessories provides vehicle-specific speed limiting modules designed to prevent drivers from exceeding pre-set maximum speeds. These systems seamlessly integrate with your vehicle’s throttle control, ensuring consistent speed management across your fleet or for individual vehicles. Tamper-proof by design, these modules maintain the set speed limit, offering peace of mind and reliable performance in various applications.
Why Choose OBD2 Speed Limiters?
OBD2 speed limiters are particularly beneficial in numerous scenarios:
- New Drivers: Limit top speeds for inexperienced drivers, promoting safer driving practices from the start.
- Construction Sites & Controlled Zones: Enforce speed limits within designated areas like construction sites, school zones, and parks, enhancing safety for workers and pedestrians.
- Fleet Management: Optimize fuel efficiency, reduce maintenance costs, and improve driver safety across large vehicle fleets.
- Rental Vehicles: Maintain vehicle integrity and encourage responsible driving habits among renters.
Understanding Rostra OBD2 Speed Limiter Systems
Rostra speed limiter systems are designed for straightforward installation and reliable operation. A typical system includes:
- Pre-programmed Control Module: The core of the system, programmed with your desired maximum speed limit.
- Accelerator Pedal Interface Harness: Ensures seamless connection to your vehicle’s throttle system.
- OBD-II Connector: Utilizes the OBD-II port for power and vehicle communication, simplifying installation.

These components work together to restrict acceleration once the vehicle reaches the pre-determined speed limit. The system intervenes by limiting the signal from the accelerator pedal, preventing further speed increases beyond the set threshold.
Cruise Control Considerations
For vehicles equipped with factory cruise control, Rostra speed limiters require an additional module to ensure comprehensive speed management. While the speed limiter restricts acceleration via the pedal, the factory cruise control could potentially override the set limit.
To address this, Rostra offers part number 250-3766, a relay module that disables cruise control functionality above the programmed speed limit. This ensures that the set speed restriction remains in effect regardless of whether the driver uses the accelerator pedal or cruise control.

When ordering your Rostra OBD2 speed limiter, remember to include part number 250-3766 if your vehicle has cruise control and you want to maintain complete speed limit enforcement.
Selecting Your Rostra Speed Limiter
Choosing the correct Rostra speed limiter is simple. Part numbers are based on vehicle application, and the desired speed limit is appended to the end of the part number. For example, to limit a 2012-2020 Nissan NV van to 65 MPH, you would order part number 250-9806-65.
Here are further examples:
- 250-9806-70: Limits speed to 70 MPH
- 250-9806-75: Limits speed to 75 MPH
- 250-9806-80: Limits speed to 80 MPH
Refer to the vehicle application tables below to find the specific part number for your vehicle and choose the speed limit that best suits your needs.
