What should you do if your tire pressure monitoring system (TPMS) turns on while driving?

  1. Change lanes

  2. Turn on your lights

  3. Check your tire pressure

  4. Stop immediately

The correct answer is: Check your tire pressure

If your tire pressure monitoring system (TPMS) turns on while driving, you should check your tire pressure as this warning is an indication that one or more of your tires may be underinflated. Changing lanes or turning on your lights is not necessary in this situation and stopping immediately may not be safe or necessary depending on the severity of the tire pressure issue. It is important to address the issue as soon as possible, but safely pulling over and checking the tire pressure is the appropriate action to take.
