1. A recreational vehicle comprising:
- a chassis;
a plurality of wheels;
a suspension coupled between the plurality of wheels and the chassis to support the chassis;
an engine supported by the chassis;
a seat supported by the chassis;
a seatbelt to secure a driver within the seat;
a seatbelt sensor configured to detect when the seatbelt is in an engaged position or a disengaged position;
a vehicle speed sensor configured to detect a speed of the vehicle;
a throttle valve configured to regulate engine power;
a throttle input device configured to control the throttle valve;
a user input to permit a user to set a maximum speed limit for the vehicle;
an engine control module in communication with the throttle valve, the seatbelt sensor, and the vehicle speed sensor, the engine control module automatically limiting the maximum speed limit to a reduced maximum speed limit upon detection of the seatbelt in the disengaged position, the engine control module automatically maintains a speed of the vehicle below the reduced maximum speed limit based on a detected engine speed and detecting an error in the vehicle speed sensor; and
a GPS device coupled to the engine control module for tracking a location of vehicle and communicating the tracked location to the engine control module.

Abstract
A recreational vehicle includes a seatbelt sensor configured to detect when a seatbelt is in an engaged position or a disengaged position and an engine control module in communication with the seatbelt sensor to automatically limit a maximum speed of the vehicle to a reduced maximum speed limit upon detection of the seatbelt is in the disengaged position.
