My 15-year-old son recently got his learner’s permit. Enjoy this video, with several more examples of how our kids are watching more than we think.

National Organizations for Youth Safety hosted a Twitter Chat, inviting partner organizations, parents and youth leaders to join a conversation about the state of youth traffic safety today – and what we can do to improve it.

There is nothing that I can remember loving more as a kid than riding my bike with all of my friends. Every ride was an adventure and we would stay out as long as we could.

Now as an adult, I still hop on a bike every opportunity I get – and it’s especially fun to ride with my nephews, Jake, 4, and Nathan, 7, who are actually starting to keep up with me, which is saying something.

There are so many good things that come from riding a bike – good exercise, a sense of freedom, it’s good for the environment – so we want to encourage all kids to strap helmets on their heads and pedal off to the park, to a friend’s house or to school.

I still remember getting my first bike. It was a lovely fall day, and I was celebrating my 5th birthday at the local park when my parents wheeled it over. And it was beautiful – a light pink frame and white tires with a white basket on the front adorned with purple, blue and yellow daisies, and shimmering multicolored streamers flowing from the handlebars.

Have you ever seen a bike train? Picture lots of excited little kids perched on bicycles, scooters, skateboards and anything else with wheels, anxiously awaiting a signal from a parent or teacher to start pedaling and rolling to school.

I was in a 7-by-10-foot room in Coyoacán, Mexico City, when Paco saw the tweet.

“A child was hit by a car in Mexico City this morning,” he announced, and I heard the combination of frustration, sorrow and exhaustion in his voice.
