Thank you for your question. If you want to interfere with the tracking system, it will be monitored by your business. The signal will disappear. However, this often happens because of poor satellite signals. So you don't have to worry about blocking the truck tracking system. The GPS jammers may interfere with your tracking system, but we suggest you buy a multi-band mobile phone jammer, which is more powerful and can also interfere with your mobile GPS signal.
