How can I determine if a motorcycle helmet is still in good condition?

To determine if a motorcycle helmet is still in good condition, you should check for any visible signs of damage such as cracks, dents, or scratches. Additionally, make sure the helmet's padding is still intact and not compressed. It is also important to check the helmet's straps and fasteners to ensure they are in good working condition. Lastly, helmets should be replaced every 5-7 years, so check the manufacturing date to see if it is still within the recommended lifespan.
