Can I use a regular microSD card in my dash cam?

You can, but it will fail prematurely — often within 3-6 months. When it fails, your dash cam will stop recording without warning, and you won't have footage when you need it. The small premium for a high-endurance card is well worth the reliability and peace of mind.

How often should I format my dash cam's microSD card?

Format the card in your dash cam (not on a computer) every 30-60 days. This resets the file system and prevents fragmentation-related errors. Most dash cams have a format option in their settings menu. Note that formatting erases all footage, so save any important clips first.
