Bicycle riding is about as safe as walking.

But when you’re riding in traffic or down a mountain trail, it can be dangerous.

Wearing a safe bicycle helmet correctly is the best way to protect your head in a crash.

Helmets have changed over the years and there are helmets made for lots of different activities.

Some are multi-purpose, but they may not be made for riding.

Start by picking one that’s certified for biking.

To choose a helmet, first find the circumference of your head where a hatband or sweatband might sit.

Use a fabric tape measure or piece of string and measure it with a ruler.

Next, make sure the helmet’s not on backwards. Hey, it happens!

Turn the dial to adjust the tension until it's snug -- nod and shake your head.

The helmet should stay in place.

Adjust the helmet so that the front edge is level across your forehead, and 1 or 2 fingerbreadths above your eyebrows.
