GPS trackers with immobilizer functions were installed in the rental cars. The company was able to constantly monitor the locations of its fleet.
Geofencing was also set around the customs checkpoints so that an alert is immediately sent to the company if any vehicles attempt to leave the country. A speed limit alert was also set to alert the company if any of their vehicles exceeded the speed limit.
The company can use the immobilizer function to remotely immobilize a vehicle to prevent reckless drivers from continuing to operate the vehicle.
